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。尽管还是测试版，但是，Nginx 已经因为它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名了。 [h2]本文是W3CGROUP在成功架设Nginx+Php Web服务器之后的一个总结，成功设置Nginx开启多域名多站点，并且不会出现502 Bad Gateway错误！[/h2] 本文测试环境如下： [h2]系统环境[/h2] [b]Linux version 2.6.9（CentOS release

[b]四、修改php-fpm配置文件[/b] 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： <?xml version="1.0" ?> <configuration> <section name="global_options"> <value name="pid_file">/usr/local/webserver/php/logs/php-fpm.pid</value> <value name="error_log">/usr/local/webserver/php/logs/php-fpm.log</value> <value name="log_level">notice</value> <value

</section> </workers> </configuration> [b]五、创建www用户组及www用户[/b] /usr/sbin/groupadd www /usr/sbin/useradd -g www www [b]六、编译安装Nginx[/b] tar zxvf nginx-0.6.35.tar.gz cd nginx-0.6.35/ 默认安装： ./configure make && make install 默认情况下，Nginx 会被安装在 /usr/local/nginx。通过设定编译选项，你可以改变这个设定。 指定编译选项安装，如： ./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module make && make install cd ../ [b]七、创建fcgi.conf文件[/b] rm -f /usr/local/webserver/nginx/conf/fcgi.conf vi /usr/local/webserver/nginx/conf/fcgi.conf 输入以下内容： 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;

$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; [b]八、编辑Nginx配置文件[/b] rm -f /usr/local/webserver/nginx/conf/nginx.conf vi /usr/local/webserver/nginx/conf/nginx.conf 输入以下内容： user www www;

access_log logs/w3c.log w3clog; } } [b]九、配置开机自动启动Nginx + PHP[/b] vi /etc/rc.local 在末尾增加以下内容： ulimit -SHn 51200 /usr/local/webserver/php/sbin/php-fpm start /usr/local/webserver/nginx/sbin/nginx [b]十、优化Linux内核参数[/b] vi /etc/sysctl.conf 在末尾增加以下内容： 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 使配置立即生效： /sbin/sysctl –p [b]做到这里，可以reboot重启Linux了，不出意外的话应该可以顺利开启Nginx[/b] [h2]平滑重启Nginx[/h2] Ps aux | grep nginx 找到Nginx的master process，假如为：5800，然后kill Kill –HUP 5800 [h2]平滑重启Php[/h2] /usr/local/webserver/php/sbin/php-fpm restart php-fpm的其他命令：start | stop | quit | restart | reload | logrotate
