nginx初步负载均衡

vm镜像：centos6.6

域名服务已配好

web01ip:192.168.146.134 www.abc.cn/bbs.abc.cn

web02ip:192.168.146.135 www.abc.cn/bbs.abc.cn

nginx主配ip：192.168.146.132

nginx副配ip：192.168.146.133

1.对web01和web02主机nginx配置：

1.1 编译安装nginx后

cd /application/nginx/

1.2 mkdir html/{www bbs}

echo "web01 www.abc,cn">html/www/index.html

echo "web01 bbs.abc,cn">html/bbs/index.html

同样在web02主机建立

echo "web02 www.abc,cn">html/www/index.html

[root@web01 nginx]# cat conf/nginx.confworker_processes  1;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    keepalive_timeout  65;    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '                      '$status $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';    server {        listen       80;        server_name  www.abc.cn;        location / {            root   html/www;            index  index.html index.htm;        }        access_log  logs/www.access.log  main;}    server {        listen       80;        server_name  bbs.abc.cn;        location / {            root   html/bbs;            index  index.html index.htm;        }        access_log  logs/bbs.access.log  main;}}

/application/nginx/sbin/nginx -t

......is ok

启动:(不启动会报invalid pid ...nginx.pid之类的)

/application/nginx/sbin/nginx

1.2加入web01/web02主机解析

[root@localhost ~]# cat /etc/hosts192.168.146.134 www.abc.cn192.168.146.134 bbs.abc.cn

2.对nginx主配和nginx副配nginx.conf编辑相同如下：

[root@localhost nginx]# cat conf/nginx.confworker_processes  1;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    keepalive_timeout  65;    upstream www_server_pools{#<==定义web服务器池，包含134,135两个web节点    server 192.168.146.134:80 weight=1;    server 192.168.146.135:80 weight=1;}    server {#<==定义代理的负载均衡域名虚拟主机        listen       80;        server_name  www.abc.cn;        location / {          proxy_pass http://www_server_pools;#<==访问www.abc.cn，请求发送给www_server_pools里的节点}  }}

2.1对ip192.168.146.132主配nginx编辑：

echo “192.168.146.132 www.abc.cn” >/etc/hosts

curl www.abc.cnweb01 www.abc,cncurl www.abc.cnweb02 www.abc,cn
