负 载 机：A机器： 192.168.71.223
后端机器1：B机器：192.168.71.224
后端机器2：C机器：192.168.71.226
需求： 1）访问A机器的8080端口，反向代理到B机器的8080端口； 访问A机器的8088端口，反向代理到C机器的8088端口； 访问http://192.168.71.223:8090/ios，反向代理到B机器http://192.168.1.102:8090/ios/ 2）访问A机器的80端口，负载均衡到后端的两台机器B和C的80端口
1、三个机器共同执行：
1）编译安装nginx yum install -y pcre* openssl* gcc gcc+ mkdir /opt/src && cd /opt/src wget http://nginx.org/download/nginx-1.8.0.tar.gz && tar -zxvf nginx-1.8.0.tar.gz && cd nginx-1.8.0 useradd www -M -s /sbin/nologin #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 vi /opt/src/nginx-1.8.0/auto/cc/gcc #CFLAGS="$CFLAGS -g" #将这句注释掉 取消Debug编译模式 大概在179行
./configure --prefix=/opt/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module #我们再配置下nginx编译参数 make && make install clean
2、机器A配置：
cd /opt/nginx/conf
vi nginx.conf
将配置改为：
worker_processes 2; events { worker_connections 65535; } http { include mime.types; default_type application/octet-stream; charset utf-8; log_format main ‘$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; }
ulimit -n 65535 mkdir vhosts && cd vhosts vi 8080.conf
将配置改为：

启动Nginx：
启动nginx： /opt/nginx/sbin/nginx -t 检查配置是否正确 #如果报缺少某个日志文件，创建目录及文件就可以 nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok nginx: configuration file /opt/nginx/conf/nginx.conf test is successful /opt/nginx/sbin/nginx 启动nginx
3、机器B配置：
cd /opt/nginx/conf && cp nginx.conf nginx.conf.bak
vi nginx.conf
将配置改为：
user www; worker_processes 2; 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; }

4、机器C配置：
cd /opt/nginx/conf && cp nginx.conf nginx.conf.bak
vi nginx.conf
将配置改为：
user www; worker_processes 2; 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; }
ulimit -n 65535 mkdir vhosts && cd vhosts vi 8080.conf
将配置改为：
server { listen 8088; server_name localhost; index index.html index.php index.htm; access_log /usr/local/nginx/logs/8088-access.log main; error_log /usr/local/nginx/logs/8088-error.log; location ~ / { root /var/www/html/8088; index index.html index.php index.htm; } }

5、创建访问目录：
机器B的目录结构为：
[root@localhost var]# tree www/
www/
└── html
├── 8080
│ └── index.html
├── 8090
│ ├── index.html
│ └── ios
│ └── index.html
└── index.html
echo ‘192.168.71.224:/var/www/html/‘ >> index.html mkdir -p /var/www/html/8080 echo ‘192.168.71.224:/var/www/html/8080‘ >> /var/www/html/8080/index.html mkdir -p /var/www/html/8090 echo ‘192.168.71.224/var/www/html/8090‘ >> /var/www/html/8090/index.html mkdir -p /var/www/html/ios echo ‘http://192.168.71.224:8090/ios/‘ >> /var/www/html/8090/ios/index.html chown www:www -R /var/www/html
机器C的目录结构为： [root@localhost var]# tree www/ www/ └── html ├── 8088 │ └── index.html └── index.html mkdir -p /var/www/html/8088 echo ‘192.168.71.226:/var/www/html‘ >> index.html echo ‘192.168.71.226:/var/www/html/8088/‘ >> /var/www/html/8080/index.html
chown www:www -R /var/www/html
6、验证：
1、访问http://192.168.71.223/显示的是：192.168.71.224:/var/www/html/，再刷新变为：192.168.71.226:/var/www/html
2、访问http://192.168.71.223:8080/显示的是：192.168.71.224:/var/www/html/8080
3、访问http://192.168.71.223:8088/显示的是：192.168.71.226:/var/www/html/8088/
4、访问http://192.168.71.223:8090/ios/显示的是：http://192.168.71.224:8090/ios/
