Redhat/CentOS 5.7 安装Nginx 1.8 及配置反向代理手册

准备安装介质：

nginx 1.8 Stable version：

wget http://nginx.org/download/nginx-1.8.0.tar.gz

ngx_cache_purge：

wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz


操作系统基本配置：

1. 创建nginx用户

# useradd nginx

设置用户密码：
# passwd nginx

修改操作系统进程数及openfiles 限制：

# vi /etc/security/limits.conf
增加如下4行：

# add by nginx
nginx           hard    nofile          65535
nginx           soft    nofile          65535
nginx           hard    nproc           4096
nginx           soft    nproc           4096

保存退出。

# vi /etc/pam.d/login

增加1行：

session    required     pam_limits.so

保存退出。

创建编译工作目录：
# mkdir nginx-src
# mv nginx-1.8.0.tar.gz   nginx-src/
# mv ngx_cache_purge-2.3.tar.gz   nginx-src/

解压缩：

# cd nginx-src
# tar xzvf nginx-1.8.0.tar.gz
# tar xzvf ngx_cache_purge-2.3.tar.gz

编译：

# cd nginx-1.8.0

#  ./configure  --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-mail --with-mail_ssl_module --with-file-aio --with-ipv6 --with-cc-opt='-O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic' --add-module=../ngx_cache_purge-2.3

# make && make install


创建cache 路径：

# mkdir –p  /var/nginx_cache

修改配置文件：

# vi /etc/nginx/conf.d/default.conf

# 反向代理缓存配置
proxy_cache_path /var/nginx_cache levels=2:2 keys_zone=websitecache:1024m inactive=1d  max_size=10g;
#反向代理服务器URL配置
server {
       listen       80;
       server_name  localhost;

        location / {
                proxy_pass      http://10.12.2.57;
                proxy_set_header  X-Real-IP  $remote_addr;

                proxy_cache       websitecache;
                proxy_cache_key $host$uri$is_args$args;
                proxy_ignore_headers   Cache-Control Set-Cookie X-Accel-Expires Expires;
                proxy_hide_header      Cache-Control;
                proxy_hide_header      Set-Cookie;
                add_header X-Cache $upstream_cache_status;

                proxy_cache_valid 200 302 25m;
                proxy_cache_valid any 1m;
        }



        #实现只代理，不缓存
        location ^~ /HQ/ {
                proxy_pass      http://10.12.2.57;
                proxy_set_header  X-Real-IP  $remote_addr;
        }

     
 
        # 只代理不缓存
        location ^~ /flash/ {
                proxy_pass     http://10.12.2.57;
                proxy_set_header  X-Real-IP  $remote_addr;
        }


        #purge 模块，实现清除指定URL缓存
        location ~ /clear(/.*) {
          allow 127.0.0.1;
          deny all;
          proxy_cache_purge websitecache $host$1$is_args$args;
        }

}

修改主配置文件：

# vi /etc/nginx/nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  2048;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';


    log_format format1  '$remote_addr - $remote_user [$time_local] "$request" '
                        '$status $body_bytes_sent "$http_referer" '
                        '"$http_user_agent" "$http_x_forwarded_for" '
                        '$request_time' ;

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    # 启用 GZIP 压缩
    gzip  on;
    gzip_static on;
    gzip_http_version 1.0;
    gzip_disable "MSIE [1-6].";
    gzip_min_length  1020;
    gzip_comp_level 5;
    gzip_proxied any;
    gzip_types  text/html text/plain text/css application/x-javascript application/javascript application/xml;


    include /etc/nginx/conf.d/*.conf;
}

修改完毕后保存退出。

注册 nginx 服务：

#chmod +x /etc/init.d/nginx

#chkconfig --add nginx

#chkconfig --level 2345 nginx on

#chkconfig --list nginx


检查配置：

# service nginx configtest

确认没问题后，启动服务：
# service nginx start

如果修改了ningx配置，需要生效：

# service nginx reload
