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):
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;}}
