特别值得一提的是Linux Nginx有很多值得学习的地方,这里我们主要介绍Linux Nginx安装编译,包括介绍Linux Nginx等方面。Linux 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。
本文是W3CGROUP在成功架设Linux Nginx+Php Web服务器之后的一个总结,成功设置Linux Nginx开启多域名多站点,并且不会出现502 Bad Gateway错误!本文测试环境如下:
系统环境Linux version 2.6.9(CentOS release 4.7(Final))软件环境nginx-0.6.35.tar.gz当前稳定版: Nginx 0.6.35 (2009年1月26日)官方Wiki:http://wiki.nginx.org官方下载:http://sysoev.ru/nginx/nginx-0.6.35.tar.gzphp-5.2.9.tar.gz官方下载:http://www.php.net/get/php-5.2.9.tar.gz/from/this/mirrorphp-5.2.9-fpm-0.5.10.diff.gz官方下载:http://php-fpm.anight.org/downloads/archive/mysql-5.1.34.tar.gzlibiconv-1.13.tar.gzlibmcrypt-2.5.8.tar.gzmcrypt-2.6.8.tar.gzmhash-0.9.9.9.tar.gz

MySql的安装此处就省略
三、Linux Nginx编译安装PHP(FastCGI模式)

- cp php.ini-dist /usr/local/webserver/php/etc/php.ini
- cd ../
四、Linux Nginx修改php-fpm配置文件
- 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:
- <?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 name="emergency_restart_threshold">10</value>
- <value name="emergency_restart_interval">1m</value>
- <value name="process_control_timeout">5s</value>
- <value name="daemonize">yes</value>
- </section>
- <workers>
- <section name="pool">
- <value name="name">default</value>

- </value>
- </section>
- </workers>
- </configuration>
五、Linux Nginx创建www用户组及www用户
- /usr/sbin/groupadd www
- /usr/sbin/useradd -g www www
六、编译安装Linux Nginx
tar zxvf nginx-0.6.35.tar.gz cd nginx-0.6.35/默认安装:./configuremake && 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_modulemake && make install cd ../
七、Linux Nginx创建fcgi.conf文件
- 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;
- 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;
八、编辑Linux Nginx配置文件
- rm -f /usr/local/webserver/nginx/conf/nginx.conf
- vi /usr/local/webserver/nginx/conf/nginx.conf
输入以下内容:
- user www www;
- worker_processes 8;
- error_log /usr/local/webserver/nginx/logs/logs/nginx_error.log crit;
- pid /usr/local/webserver/nginx/logs/nginx.pid;
- worker_rlimit_nofile 51200;
- events {
- use epoll;
- worker_connections 51200;
- }
- http {
- include mime.types;
- default_type application/octet-stream;
- charset utf-8;
- server_names_hash_bucket_size 128;
- client_header_buffer_size 32k;
- large_client_header_buffers 4 32k;
- client_max_body_size 8m;
- sendfile on;
- tcp_nopush on;
- keepalive_timeout 60;
- tcp_nodelay on;
- fastcgi_connect_timeout 300;
- fastcgi_send_timeout 300;
- fastcgi_read_timeout 300;
- fastcgi_buffer_size 64k;
- fastcgi_buffers 8 64k;
- fastcgi_busy_buffers_size 128k;
- fastcgi_temp_file_write_size 128k;
- gzip on;
- gzip_min_length 1k;
- gzip_buffers 4 16k;
- gzip_http_version 1.0;
- gzip_comp_level 2;
- gzip_types text/plain application/x-javascript text/css application/xml;
- gzip_vary on;
- #limit_zone crawler $binary_remote_addr 10m;
- #多个站点设置,站点文件夹必须放在Nginx的html目录,否则不支持多站点
- server {
- listen 80;
- server_name www.v-ec.com;
- root /usr/local/webserver/nginx/html/www.v-ec.com;
- index index.php index.html;
- location ~ .*\.(php|php5)?$ {
- #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 6h;
- }
- log_format veclog '$remote_addr - $remote_user [$time_local] "$request" '
- '$status $body_bytes_sent "$http_referer" '
- '"$http_user_agent" $http_x_forwarded_for';
- access_log logs/vec.log veclog;
- }
- #多个站点设置,站点文件夹必须放在Nginx的html目录,否则不支持多站点
- server {
- listen 80;
- server_name www.w3cgroup.com;
- root /usr/local/webserver/nginx/html/www.w3cgroup.com;
- index index.php index.html;
- location ~ .*\.(php|php5)?$ {
- #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 6h;
- }
- log_format w3cclog '$remote_addr - $remote_user [$time_local] "$request" '
- '$status $body_bytes_sent "$http_referer" '
- '"$http_user_agent" $http_x_forwarded_for';
- access_log logs/w3c.log w3clog;
- }
- }
九、配置开机自动启动Linux Nginx + PHP
- 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
十、Linux Nginx优化Linux内核参数
- 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
