分发hosts文件到其它服务器

[root@centos ~]# useradd fenfa -u 999[root@centos ~]# echo "123456"|passwd --stdin fenfaChanging password for user fenfa.passwd: all authentication tokens updated successfully.[root@centos ~]# /bin/cp /etc/sudoers /etc/sudoers.bak[root@centos ~]# echo "fenfa ALL=(root) NOPASSWD:/usr/bin/rsync" >>/etc/sudoers[root@centos ~]# tail -1 /etc/sudoersfenfa ALL=(root) NOPASSWD:/usr/bin/rsync

切换到fenfa用户创建密钥

[fenfa@centos ~]$ vim fenfa.exp#!/usr/bin/expectif {
  $argc != 2} {send_user "usage: expect xxxx.exp file host\n"  it}#define varset file [lindex $argv 0]set host [lindex $argv 1]set password "123456"spawn ssh-copy-id -i $file  fenfa@$hostexpect {        "yes/no"   {send "yes\r";exp_continue}         "password" {send "$password\r"}}expect eof[fenfa@centos ~]$ vim fenfa_key.sh#!/bin/sh. /etc/init.d/functionsfor ip in `cat host.list`doexpect fenfa.exp ~/.ssh/id_dsa.pub $ip >/dev/null 2>&1if [ $? -eq 0 ];then   action "$ip" /bin/true else   action "$ip" /bin/falsefidone

执行脚本结果如下

[fenfa@centos ~]$ sh fenfa_key.sh10.0.0.1                         [  OK  ]10.0.0.2                         [  OK  ]10.0.0.3                         [  OK  ]10.0.0.4                         [  OK  ]10.0.0.5                         [  OK  ]10.0.0.6                         [  OK  ]10.0.0.7                         [  OK  ]10.0.0.8                         [  OK  ]10.0.0.9                         [  OK  ]10.0.0.10                        [  OK  ]10.0.0.11                        [  OK  ]10.0.0.12                        [  OK  ]10.0.0.13                        [  OK  ]10.0.0.14                        [  OK  ][root@centos ~]# su - fenfa[fenfa@centos ~]$ ll /home/fenfa/.ssh/total 4-rw------- 1 fenfa fenfa 602 Sep 21 12:14 authorized_keys

编写分发文件脚本

**前端反向代理及管理后台服务器的配置

[root@centos ~]# yum install pcre-devel zlib-devle openssl-devel gcc-c++ –y

编译安装nginx

cd /download/tools/wget http://nginx.org/download/nginx-1.12.1.tar.gztar zxf nginx-1.12.1.tar.gzcd nginx-1.12.1./configure --prefix=/app/nginx-1.12.1make && make install[root@centos ~]# cd /app/[root@centos app]# ln -s nginx-1.12.1 nginx[root@centos ~]# cd /app/nginx/conf/[root@centos conf]# mkdir extra[root@centos conf]# cp nginx.conf nginx.conf.bak

在nginx.conf文件后增加下面的配置

include extra/*.conf;[root@centos ~]# cd /app/nginx/conf/extra/[root@centos extra]# vim admin.mingongge.conf## HTTPS server configuration#server {    listen       80;    server_name admin.mingongge.com;    location / {        proxy_pass http://10.0.0.6:8080;        proxy_connect_timeout 600;        proxy_read_timeout 600;        proxy_send_timeout 600;    }}[root@centos extra]# vim shangjia.mingongge.conf## HTTPS server configuration#server {    listen       80;    server_name shangjia.mingongge.com;    location / {        proxy_pass http://10.0.0.7:8080;        proxy_connect_timeout 600;        proxy_read_timeout 600;        proxy_send_timeout 600;    }}

**业务平台管理后台admin.mingongge.com

tar zxf apache-tomcat-8.5.9.tar.gzmv apache-tomcat-8.5.9 /usr/local/tomcattar zxf jdk-8u111-linux-x64.tar.gz -C /usr/local/cd /usr/local/ln -s jdk1.8.0_111 jdkcat >>/etc/profile <

JDK Tomcat环境配置

   echo "this is the admin.mingongge.com" >/www/admin/index.html/usr/local/tomcat/bin/startup.sh

商家管理后台 shangjia.mingongge.com

JDK Tomcat环境安装请参考前面的步骤
   echo "this is the shangjia.mingongge.com" >/www/shangjia/index.html/usr/local/tomcat/bin/startup.sh

测试反向代理

[root@centos ~]# curl http://admin.mingongge.comthis is the admin.mingongge.com[root@centos ~]# curl http://shangjia.mingongge.comthis is the shangjia.mingongge.com
