前言:本文为我2007年9月写过的文章《Nginx 0.5.31 + PHP 5.2.4(FastCGI)搭建可承受3万以上并发连接数,胜过Apache 10倍的Web服务器》的第2版,经过了多台服务器的测试,修正了PHP iconv和gd库冲突的BUG,增加了PHP mcrypt、memcache扩展,修改了PHP和Nginx编译参数,优化了Nginx配置文件,添加了部分功能。
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两年半了。Igor 将源代码以类BSD许可证的形式发布。

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 0.5.33 + PHP 5.2.5 (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 0.5.33 + PHP 5.2.5 (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 0.5.33 + PHP 5.2.5 (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):

安装步骤:
(系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 4.4)
一、获取相关开源程序:
1、下载程序源码包到当前目录:
本文中提到的所有开源软件为截止到2007年11月25日的最新稳定版。我将它们打了两个压缩包。
第一个压缩包:nginx-php-1.zip
下载地址:http://ishare.iask.sina.com.cn/cgi-bin/fileid.cgi?fileid=2746375
第二个压缩包:nginx-php-2.zip
下载地址:http://ishare.iask.sina.com.cn/cgi-bin/fileid.cgi?fileid=2746370
附:各开源软件单独下载地址(如果下载了以上两个压缩包,则无需下载以下软件):
http://down.zyan.cc/linux/nginx-php/ (登录用户名、密码均为blog.zyan.cc)
2、解压缩:
二、安装PHP 5.2.5(FastCGI模式)
1、编译安装PHP 5.2.5所需的支持库:
2、编译安装MySQL 5.0.45
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,则执行以下两步。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、以mysql用户帐号的身份建立数据表:
②、启动MySQL(最后的&表示在后台运行)
3、编译安装PHP(FastCGI模式)
4、编译安装PHP5扩展模块
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 = "gd.so"
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:
6、创建www用户和组,以及其使用的目录:
7、安装lighttpd中附带的spawn-fcgi,用来启动php-cgi
注:压缩包中的spawn-fcgi程序为已经编译成二进制的版本。
8、启动php-cgi进程,监听127.0.0.1的10080端口,进程数为64(如果服务器内存小于3GB,可以只开启25个进程),用户为www:
三、安装Nginx 0.5.33
1、安装Nginx所需的pcre库:
2、安装Nginx
3、创建Nginx日志目录
4、创建Nginx配置文件
①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件:
输入以下内容:
②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件:
输入以下内容:
5、启动Nginx
四、配置开机自动启动Nginx + PHP
在末尾增加以下内容:
五、优化Linux内核参数
在末尾增加以下内容:
使配置立即生效:
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:
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)、这时,输入以下命令查看Nginx主进程号:
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:

cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf
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,则执行以下两步。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、以mysql用户帐号的身份建立数据表:
/usr/local/webserver/mysql/bin/mysql_install_db --defaults-file=/usr/local/webserver/mysql/my.cnf --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql --pid-file=/usr/local/webserver/mysql/mysql.pid --skip-locking --port=3306 --socket=/tmp/mysql.sock
②、启动MySQL(最后的&表示在后台运行)
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &
3、编译安装PHP(FastCGI模式)
tar zxvf php-5.2.5.tar.gz
cd php-5.2.5/
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-debug --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-force-cgi-redirect --enable-mbstring --with-mcrypt

sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile
make
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-2.2.1.tgz
cd memcache-2.2.1/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../
cd php-5.2.5/ext/gd/
/usr/local/webserver/php/bin/phpize
./configure --with-jpeg-dir --with-png-dir --with-zlib-dir --with-ttf --with-freetype-dir --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../../../
cd memcache-2.2.1/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../
cd php-5.2.5/ext/gd/
/usr/local/webserver/php/bin/phpize
./configure --with-jpeg-dir --with-png-dir --with-zlib-dir --with-ttf --with-freetype-dir --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 = "gd.so"
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 = "gd.so"\n#' /usr/local/webserver/php/etc/php.ini
6、创建www用户和组,以及其使用的目录:
/usr/sbin/groupadd www -g 48
/usr/sbin/useradd -u 48 -g www www
mkdir -p /data0/vshare/htdocs
chmod +w /data0/vshare/htdocs
chown -R www:www /data0/vshare/htdocs
/usr/sbin/useradd -u 48 -g www www
mkdir -p /data0/vshare/htdocs
chmod +w /data0/vshare/htdocs
chown -R www:www /data0/vshare/htdocs
7、安装lighttpd中附带的spawn-fcgi,用来启动php-cgi
注:压缩包中的spawn-fcgi程序为已经编译成二进制的版本。
cp spawn-fcgi /usr/local/webserver/php/bin
chmod +x /usr/local/webserver/php/bin/spawn-fcgi
chmod +x /usr/local/webserver/php/bin/spawn-fcgi
8、启动php-cgi进程,监听127.0.0.1的10080端口,进程数为64(如果服务器内存小于3GB,可以只开启25个进程),用户为www:
/usr/local/webserver/php/bin/spawn-fcgi -a 127.0.0.1 -p 10080 -C 64 -u www -f /usr/local/webserver/php/bin/php-cgi
三、安装Nginx 0.5.33
1、安装Nginx所需的pcre库:
tar zxvf pcre-7.2.tar.gz
cd pcre-7.2/
./configure
make && make install
cd ../
cd pcre-7.2/
./configure
make && make install
cd ../
2、安装Nginx
tar zxvf nginx-0.5.33.tar.gz
cd nginx-0.5.33/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module
make && make install
cd ../
cd nginx-0.5.33/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_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
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
vi /usr/local/webserver/nginx/conf/nginx.conf
输入以下内容:

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 51200
/usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
/usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
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 51200
/usr/local/webserver/php/bin/spawn-fcgi -a 127.0.0.1 -p 10080 -C 64 -u www -f /usr/local/webserver/php/bin/php-cgi
/usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
/usr/local/webserver/php/bin/spawn-fcgi -a 127.0.0.1 -p 10080 -C 64 -u www -f /usr/local/webserver/php/bin/php-cgi
/usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
五、优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容:
引用
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000
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)、这时,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
