nginx回顾

nginx又搞了搞,不过这破玩意简单确实简单,有时候忘记了也干着急.

nginx编译安装

yum install openssl-devel pcre-devel -y

useradd -u520 -M -s /sbin/nologin

cd /usr/local/src

sz nginx-1.6.2.tar.gz

tar xf nginx-1.6.2.tar.gz

cd nginx-1.6.2

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module--with-http_ssl_module

make && make install

/usr/local/nginx/sbin/nginx

简化nginx.conf,空格和#开头的都去了.

egrep -v "^$|#" nginx.conf.default > nginx.conf

 

server标签里改改

server {

listen 80;

server_name www.example.com; #配个server_name

location / {

#干掉

}

}

查阅nginx.org的proxy模块

upstream web-pools { #给这组服务器取个名字

#ip_hash

server 192.168.14.130:80 weight=1 max_fails=1 fail_timeout=60s; #后端80,一次down就剔除.即使恢复后60s才可以在加入.

server 192.168.14.131:80 weight=1;

#server 192.168.14.131:8080 weight=1 backup; #备份节点

}

#算法: ip_hash和wrr算法.

server {

listen 80;

server_name www.example.com;

location / {

proxy_set_header Host $host;

proxy_set_header X-Forwarded-For $remote_addr; #为了后端能看到真实客户的ip.

proxy_pass http://web-pools; #抛给后端服务器

}

}

nginx status重新添加个server标签.编译装的时候已经装了--with-http_stub_status_module

server {

listen 80;

server_name 192.168.14.128;

location /status {

stub_status on;

access_log /opt/lb01-status.log;

allow 192.168.14.132;

deny all;

}

}
