Nginx集群搭建笔记

源码安装Nginx:

$ tar -zxvf nginx-1.8.0.tar.gz -C /nginx/        #解压Nginx
$ rpm -ivh keepalived-1.2.13-5.el6_6.i686.rpm        #安装keepalived
$ service iptables status        #查看系统防火墙状态
$ service iptables stop           #停止系统防火墙(重启后恢复)
$ chkconfig iptables --list       #查看系统防火墙
$ chkconfig iptables off          #禁用防火墙

安装pre库:

$ yum install -y pcre-devel     #在线或离线安装
# 添加软连接:
$ cd /lib/
$ ls *pcre*
$ find / -type f -name *libpcre.so.*
$ ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1

编译安装Nginx:

$ cd　/nginx/ 
$ make && make install
$ cd /usr/local/nginx/
$ ./sbin/nginx     #启动Nginx服务器
# http://192.168.38.128/浏览器访问,测试nginx是否可用
# ps -aux | grep nginx查看nginx进程
# ./sbin/nginx -s stop停止nginx(不使用)
# ./sbin/nginx -s quit完成任务退出
# ./sbin/nginx -s reload相当于重启(加载配置文件)
# ./sbin/nginx -t    检查nginx.conf配置文件语法
# nginx -V    查看版本

进入tomcat1

$ sh ./apache-tomcat-7.0.47/bin/startup.sh
$ tail -n 300 catalina.out 
# http://192.168.38.131:8080/

安装keepalived:

rpm -qa | grep openssl
rpm -ivh keepalived-1.2.13-5.el6_6.i686.rpm
rpm -ql keepalived
service keepalived start
service keepalived restart
service keepalived stop
tail -f /var/log/messages
ip add show eth0
vim check_nginx.sh
http://192.168.38.136/可以访问tomcat
./check_nginx.sh//先关闭Nginx

Nginx代理配置(代理多个tomcat):

1. server {
   listen 80;
   server_name localhost;
   #charset koi8-r;
   #access_log logs/host.access.log main;
   location /jenkins {
   proxy_pass http://localhost:8082;
   }
   location /go {
   proxy_pass http://localhost:8153;
   }
   error_page 500502503504/50x.html;
   location =/50x.html {
   root html;
   }
   }
