30.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        启动nginx

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 {
2. listen 80;
3. server_name localhost;
5. #charset koi8-r;
7. #access_log logs/host.access.log main;
8. location /jenkins {
9. proxy_pass http://localhost:8082;
10. }
11. location /go {
12. proxy_pass http://localhost:8153;
13. }
14. error_page 500502503504/50x.html;
15. location =/50x.html {
16. root html;
17. }
18. }
