Nginx反向代理+负载均衡简单实现（http方式）(5)

启动nginx
[root@nginx-1.8.0 vhosts]# /opt/nginx/sbin/nginx -t 【检查配置是否正确】
nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful
[root@host-192-168-1-102 vhosts]# /opt/nginx/sbin/nginx 【启动nginx】

--------------------------------------------------------------------------------------
后端机：C机器上的操作记录：
1）编译安装nginx
[root@C ~]# yum install -y pcre* openssl* gcc gcc+
[root@C ~]# cd /opt/src
[root@C ~]# wget
[root@C ~]# tar -zxvf nginx-1.8.0.tar.gz
[root@C ~]# cd nginx-1.8.0
#添加www用户，其中-M参数表示不添加用户家目录，-s参数表示指定shell类型

[root@nginx-1.8.0 ~]#useradd www -M -s /sbin/nologin
[root@nginx-1.8.0 ~]##vim auto/cc/gcc
#将这句注释掉 取消Debug编译模式 大概在179行
#CFLAGS="$CFLAGS -g"

#我们再配置下nginx编译参数
[root@nginx-1.8.0 ~]# ./configure --prefix=/opt/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module
[root@nginx-1.8.0 ~]#make
[root@nginx-1.8.0 ~]#make install clean

2）配置nginx
[root@nginx-1.8.0 ~]# cd /opt/nginx/conf
注意，把默认的nginx.conf文件中的server区域配置注释掉，设置vhosts虚拟主机的配置，如下：
[root@nginx-1.8.0 conf]# vim nginx.conf

user  www;

worker_processes  8;

   

events {

    worker_connections  65535;

}

   

http {

    include      mime.types;

    default_type  application/octet-stream;

    charset utf-8;

  

    log_format  main  '$http_x_forwarded_for $remote_addr $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_cookie" $host $request_time';

    sendfile      on;

    tcp_nopush    on;

    tcp_nodelay    on;

    keepalive_timeout  65;

  

  

    fastcgi_connect_timeout 3000;

    fastcgi_send_timeout 3000;

    fastcgi_read_timeout 3000;

    fastcgi_buffer_size 256k;

    fastcgi_buffers 8 256k;

    fastcgi_busy_buffers_size 256k;

    fastcgi_temp_file_write_size 256k;

    fastcgi_intercept_errors on;

   

      

    client_header_timeout 600s;

    client_body_timeout 600s;

   

    client_max_body_size 100m;           

    client_body_buffer_size 256k;         

   

    gzip  on;

    gzip_min_length  1k;

    gzip_buffers    4 16k;

    gzip_http_version 1.1;

    gzip_comp_level 9;

    gzip_types      text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php;

    gzip_vary on;

   

  

    include vhosts/*.conf;

}

[root@nginx-1.8.0 conf]# vim 80.conf

server {

    listen 80;

    server_name localhost;

    index index.html index.php index.htm;

  

    access_log  /usr/local/nginx/logs/80-access.log main;

    error_log  /usr/local/nginx/logs/80-error.log;

 

location ~ / {

    root /var/www/html/;

    index index.html index.php index.htm;

}

}
