  Nginx ("engine x") 是一个高性能的 HTTP 和反向代理服务器,也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的,它已经在该站点运行超过三年了。Igor 将源代码以类BSD许可证的形式发布。

  Nginx 超越 Apache 的高性能和稳定性,使得国内使用 Nginx 作为 Web 服务器的网站也越来越多,其中包括新浪博客新浪播客网易新闻腾讯网搜狐博客等门户网站频道,六间房56.com等视频分享网站,Discuz!官方论坛水木社区等知名论坛,盛大在线金山逍遥网等网络游戏网站,豆瓣人人网YUPOO相册金山爱词霸迅雷在线等新兴Web 2.0网站。

  在高并发连接的情况下,Nginx是Apache服务器不错的替代品。Nginx同时也可以作为7层负载均衡服务器来使用。根据我的测试结果,Nginx 0.8.46 + PHP 5.2.14 (FastCGI) 可以承受3万以上的并发连接数,相当于同等环境下Apache的10倍

  根据我的经验,4GB内存的服务器+Apache(prefork模式)一般只能处理3000个并发连接,因为它们将占用3GB以上的内存,还得为系统预留1GB的内存。我曾经就有两台Apache服务器,因为在配置文件中设置的MaxClients为4000,当Apache并发连接数达到3800时,导致服务器内存和Swap空间用满而崩溃。

  而这台 Nginx 0.8.46 + PHP 5.2.14 (FastCGI) 服务器在3万并发连接下,开启的10个Nginx进程消耗150M内存(15M*10=150M),开启的64个php-cgi进程消耗1280M内存(20M*64=1280M),加上系统自身消耗的内存,总共消耗不到2GB内存。如果服务器内存较小,完全可以只开启25个php-cgi进程,这样php-cgi消耗的总内存数才500M。

  在3万并发连接下,访问Nginx 0.8.46 + PHP 5.2.14 (FastCGI) 服务器的PHP程序,仍然速度飞快。下图为Nginx的状态监控页面,显示的活动连接数为28457(关于Nginx的监控页配置,会在本文接下来所给出的Nginx配置文件中写明):

  我生产环境下的两台Nginx + PHP5(FastCGI)服务器,跑多个一般复杂的纯PHP动态程序,单台Nginx + PHP5(FastCGI)服务器跑PHP动态程序的处理能力已经超过“700次请求/秒”,相当于每天可以承受6000万(700*60*60*24=60480000)的访问量(更多信息见此),而服务器的系统负载也不高:

  2009年9月3日下午2:30,金山游戏《剑侠情缘网络版叁》临时维护1小时(http://kefu.xoyo.com/gonggao/jx3/2009-09-03/750438.shtml),大量玩家上官网,论坛、评论、客服等动态应用Nginx服务器集群,每台服务器的Nginx活动连接数达到2.8万,这是笔者遇到的Nginx生产环境最高并发值。

  下面是用100个并发连接分别去压生产环境中同一负载均衡器VIP下、提供相同服务的两台服务器,一台为Nginx,另一台为Apache,Nginx每秒处理的请求数是Apache的两倍多,Nginx服务器的系统负载、CPU使用率远低于Apache:

  你可以将连接数开到10000~30000,去压Nginx和Apache上的phpinfo.php,这是用浏览器访问Nginx上的phpinfo.php一切正常,而访问Apache服务器的phpinfo.php,则是该页无法显示。4G内存的服务器,即使再优化,Apache也很难在“webbench -c 30000 -t 60 http://xxx.xxx.xxx.xxx/phpinfo.php”的压力情况下正常访问,而调整参数优化后的Nginx可以。

  webbench 下载地址:http://blog.zyan.cc/post/288/

  注意:webbench 做压力测试时,该软件自身也会消耗CPU和内存资源,为了测试准确,请将 webbench 安装在别的服务器上。

  为什么Nginx的性能要比Apache高得多?这得益于Nginx使用了最新的epoll(Linux 2.6内核)和kqueue(freebsd)网络I/O模型,而Apache则使用的是传统的select模型。目前Linux下能够承受高并发访问的Squid、Memcached都采用的是epoll网络I/O模型。

  处理大量的连接的读写,Apache所采用的select网络I/O模型非常低效。下面用一个比喻来解析Apache采用的select模型和Nginx采用的epoll模型进行之间的区别:

  假设你在大学读书,住的宿舍楼有很多间房间,你的朋友要来找你。select版宿管大妈就会带着你的朋友挨个房间去找,直到找到你为止。而epoll版宿管大妈会先记下每位同学的房间号,你的朋友来时,只需告诉你的朋友你住在哪个房间即可,不用亲自带着你的朋友满大楼找人。如果来了10000个人,都要找自己住这栋楼的同学时,select版和epoll版宿管大妈,谁的效率更高,不言自明。同理,在高并发服务器中,轮询I/O是最耗时间的操作之一,select和epoll的性能谁的性能更高,同样十分明了。



  安装步骤:
  (系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 5.3,另在RedHat AS4上也安装成功)

  一、获取相关开源程序:
  1、【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库(RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包,进行安装):
sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers


  2、【适用RedHat操作系统】RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包(事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在,通常是“xxx-devel”不存在,需要安装)。RedHat可以直接利用CentOS的RPM包安装,以下是RPM包下载网址:
  ①、RedHat AS4 & CentOS 4
  http://mirrors.163.com/centos/4/os/i386/CentOS/RPMS/
  http://mirrors.163.com/centos/4/os/x86_64/CentOS/RPMS/

  ②、RedHat AS5 & CentOS 5
  http://mirrors.163.com/centos/5/os/i386/CentOS/
  http://mirrors.163.com/centos/5/os/x86_64/CentOS/

  ③、RPM包搜索网站
  http://rpm.pbone.net/
  http://www.rpmfind.net/

  ④、RedHat AS4 系统环境,通常情况下缺少的支持包安装:
  Ⅰ、i386 系统

  Ⅱ、x86_64 系统


  3、【适用CentOS、RedHat及其它Linux操作系统】下载程序源码包:

wget http://blog.zyan.cc/soft/linux/nginx_php/imagick/imagick-2.3.0.tgz



  二、安装PHP 5.2.14(FastCGI模式)
  1、编译安装PHP 5.2.14所需的支持库:
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../



  2、编译安装MySQL 5.5.3-m3
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-5.5.3-m3/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ../



  附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下几步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。

  ①、创建MySQL数据库存放目录
mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/


  ②、以mysql用户帐号的身份建立数据表:
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql


  ③、创建my.cnf配置文件:
vi /data0/mysql/3306/my.cnf

  输入以下内容:

expire_logs_days = 30
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1

#log-slow-queries = /data0/mysql/3306/slow.log
#long_query_time = 10

[mysqldump]
quick
max_allowed_packet = 32M


  ④、创建管理MySQL数据库的shell脚本:
vi /data0/mysql/3306/mysql

  输入以下内容(这里的用户名admin和密码12345678接下来的步骤会创建):
#!/bin/sh

mysql_port=3306
mysql_username="admin"
mysql_password="12345678"

function_start_mysql()
{
    printf "Starting MySQL...\n"
    /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}

function_stop_mysql()
{
    printf "Stoping MySQL...\n"
    /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}

function_restart_mysql()
{
    printf "Restarting MySQL...\n"
    function_stop_mysql
    sleep 5
    function_start_mysql
}

function_kill_mysql()
{
    kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
    kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}

if [ "$1" = "start" ]; then
    function_start_mysql
elif [ "$1" = "stop" ]; then
    function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
    printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"
fi

  ⑤、赋予shell脚本可执行权限:
chmod +x /data0/mysql/3306/mysql


  ⑥、启动MySQL:
/data0/mysql/3306/mysql start


  ⑦、通过命令行登录管理MySQL服务器(提示输入密码时直接回车):
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock


  ⑧、输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';


  ⑨、(可选)停止MySQL:
/data0/mysql/3306/mysql stop



  3、编译安装PHP(FastCGI模式)
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/webserver/php/etc/php.ini
cd ../



  4、编译安装PHP5扩展模块
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../


  5、修改php.ini文件
  手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
  修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
  并在此行后增加以下几行,然后保存:
  extension = "memcache.so"
  extension = "pdo_mysql.so"
  extension = "imagick.so"

  再查找output_buffering = Off
  修改为output_buffering = On

  再查找; cgi.fix_pathinfo=0
  修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。

  自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini


  6、配置eAccelerator加速PHP:
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/php/etc/php.ini

  按shift+g键跳到配置文件的最末尾,加上以下配置信息:
引用
[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"




  7、创建www用户和组,以及供blog.zyan.cc和www.zyan.cc两个虚拟主机使用的目录:
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www


  8、创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):
  在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件:
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vi /usr/local/webserver/php/etc/php-fpm.conf

  输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):

  </workers>

</configuration>
  9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start

  注:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。



  三、安装Nginx 0.8.46
  1、安装Nginx所需的pcre库:
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ../


  2、安装Nginx
tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../


  3、创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs


  4、创建Nginx配置文件
  ①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件:
rm -f /usr/local/webserver/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf

  输入以下内容:
引用

    index index.html index.htm index.php;
    root  /data0/htdocs/blog;

    #limit_conn   crawler  20;    
                            
    location ~ .*\.(php|php5)?$
    {      
      #fastcgi_pass  unix:/tmp/php-cgi.sock;
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fcgi.conf;
    }
    
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
      expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
      expires      1h;
    }    

    log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
    access_log  /data1/logs/access.log  access;
      }

  server
  {
    listen       80;
    server_name  www.zyan.cc;
    index index.html index.htm index.php;
    root  /data0/htdocs/www;

    location ~ .*\.(php|php5)?$
    {      
      #fastcgi_pass  unix:/tmp/php-cgi.sock;
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fcgi.conf;
    }

    log_format  wwwlogs  '$remote_addr - $remote_user [$time_local] "$request" '

               '"$http_user_agent" $http_x_forwarded_for';
    access_log  /data1/logs/wwwlogs.log  wwwlogs;
  }

  server
  {
    listen  80;
    server_name  status.blog.zyan.cc;

    location / {
    stub_status on;
    access_log   off;
    }
  }
}


  ②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件:
vi /usr/local/webserver/nginx/conf/fcgi.conf

  输入以下内容:
引用
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;


  5、启动Nginx
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx



  四、配置开机自动启动Nginx + PHP
vi /etc/rc.local

  在末尾增加以下内容:
引用
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx



  五、优化Linux内核参数
vi /etc/sysctl.conf

  在末尾增加以下内容:
引用
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535


  使配置立即生效:
/sbin/sysctl -p



  六、在不停止Nginx服务的情况下平滑变更Nginx配置
  1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:
/usr/local/webserver/nginx/sbin/nginx -t

  如果屏幕显示以下两行信息,说明配置文件正确:
  the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
  the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully


  2、平滑重启:
  ①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:
/usr/local/webserver/nginx/sbin/nginx -s reload


  ②、对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号:
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

  屏幕显示的即为Nginx主进程号,例如:
  6302
  这时,执行以下命令即可使修改过的Nginx配置文件生效:
kill -HUP 6302

  或者无需这么麻烦,找到Nginx的Pid文件:
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`



  七、编写每天定时切割Nginx日志的脚本
  1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh
vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

  输入以下内容:
引用
#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`


  2、设置crontab,每天凌晨00:00切割nginx访问日志
crontab -e

  输入以下内容:
引用
00 00 * * * /bin/bash  /usr/local/webserver/nginx/sbin/cut_nginx_log.sh




  本文若有小的修改,会第一时间在以下网址发布:
  http://blog.zyan.cc/nginx_php_v6/



  附:文章修改历史

  ● [2010年03月04日] [Version 6.0] 新建

  ● [2010年04月16日] [Version 6.1] Nginx版本升级到0.8.35。

  ● [2010年05月14日] [Version 6.2] Nginx版本升级到0.8.36。MySQL版本升级到5.5.3-m3,my.cnf配置文件中的thread_concurrency、master-connect-retry参数在新版本中不支持,已经注释掉。

  ● [2010年07月26日] [Version 6.3] Nginx版本升级到0.8.46。PHP版本升级到5.2.14。其他软件也做了相应的升级。开启php.ini中的cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。

Address to accept fastcgi requests on.
Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'
      <value name="listen_address">127.0.0.1:9000</value>
张老师,这里如果使用 socket的话,改怎么配置呢,我在nginx.conf里面配置了个 fastcgi_pass  unix:/tmp/php-cgi.sock;,然后在php-fpm.conf里面配置相同的路径,php-fpm会直接被锁死

今天参照张兄的文章,做成了一键安装的lnmp,发现在centos5.3下有三个问题
1、安装mcrypt-2.6.8.tar.gz时,会有这样的提示:
/bin/rm: cannot remove `libtoolT’: No such file or directory
我处理的方法:vi configure,把 $RM “$cfgfile” 那行用#号注释,重新再运行 ./configure 就可以了。

2、vi /etc/rc.local
在末尾增加以下内容:
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx

其实,这根本是没用的,当重启后ulimit -n 你会发现又变成1024,
解决的方法:
echo '* soft nofile 65535' >> /etc/security/limits.conf
echo '* hard nofile 65535' >> /etc/security/limits.conf

然后是没有 /tmp/mysql.sock的问题,其实默认/tmp是drwxrwxrwt的权限,完全没有问题的,不过我一室友用vmware架设的时候也遇到这样的问题,后来我一查,空间不足~残念~!

3、关于nginx日志分割的脚本
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid` 在Centos5.3通不过,提示
-bash:kill cat /usr/local/webserver/nginx/nginx.pid :arguments must be process or job IDs

于是改成  cat /usr/local/webserver/nginx/nginx.pid|xargs kill -USR1

最后,十分感谢张兄高贵的文章

关于rewrite规则却一无所知,希望你能帮我把apache的rewrite转换成nginx的.
RewriteEngine on
RewriteCond   %{HTTP_HOST} ^[^.]+\.mydomain\.com$
RewriteRule   ^(.+)  %{HTTP_HOST}$1 [C]
RewriteRule ^www  http://www.mydomain.com [L]
RewriteRule  ^[^.]+\.mydomain\.com(.*) /www/htdocs/company/$1 [L]

我的目的是把'www.mydomain.com 和mydomain.com '以外的域名指到/www/htdocs/company/下.或者直接帮我转换上面的rewrite就可以.谢谢了.
