脚本自动部署构架集群和监控状态

shell脚本编写
自动部署、初始配置、并启动nginx反向代理服务

 1 #!/bin/bash
 2 systemctl disable firewalld
 3 systemctl stop firewalld
 4 setenforce 0

 6 yum install epel-release -y
 7 yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

自动部署、初始配置、并启动三台web

 1 #!/bin/bash
 2 systemctl disable firewalld
 3 systemctl stop firewalld
 4 setenforce 0

 6 yum install epel-release -y
 7 yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
 8 yum install nginx -y
 9 echo ‘nginx 服务已经安装好‘
10 ####
11 systemctl start  nginx
12 #read -p "please input the ip of the web1:" web1
13 #echo  "$web1     web1" >> /etc/hosts
14 read -p "please input the ip of the proxy:" proxy
15 echo  "$proxy     proxy" >> /etc/hosts
16 ####
17 #sed -i -r  ‘/http( )(\{)/a\upstream ruan {\nserver web1:80;\nserver web2:80;\n}‘ /etc/nginx/nginx.conf
18 sed -i -r  ‘/(^ +)location( )(\/)/a\ root /var/www/html;\nindex index.html;‘ /etc/nginx/nginx.conf
19 mkdir -p /var/www/html
20 echo `hostname` > /var/www/html/index.html
21 echo  "nginx配置完成"
22 systemctl restart  nginx
23 echo ‘nginx 已经运行‘
24 ####
25 yum install rpcbind nfs-utils -y
26 echo "nfs服务安装完成"
27 ####
28 systemctl enable rpcbind.service
29 systemctl enable nfs-server.service
30 systemctl start rpcbind.service
31 systemctl start nfs-server.service
32 mount -t nfs $proxy:/share /var/www/html/
33 echo "welcome" > /var/www/html/index.html          

编写监控脚本，监控集群中nginx、nfs以及机器运行状况。异常则发送报警邮件
