分发hosts文件到其它服务器
分发服务器使用全网备份服务器
首先创建分发用户

[root@centos ~]# useradd fenfa -u 999
[root@centos ~]# echo "123456"|passwd --stdin fenfa
Changing 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/sudoers
fenfa ALL=(root) NOPASSWD:/usr/bin/rsync

切换到fenfa用户创建密钥

安装配置expect服务
[root@centos ~]$ yum install expect* -y
编写脚本
Linux系统集群架构线上项目配置实战(二)

[fenfa@centos ~]$ vim fenfa.exp
#!/usr/bin/expect
if {$argc != 2} {
send_user "usage: expect xxxx.exp file host\n"
  it
}
#define var
set file [lindex $argv 0]
set host [lindex $argv 1]
set password "123456"

spawn ssh-copy-id -i $file  fenfa@$host
expect {
        "yes/no"   {send "yes\r";exp_continue}
         "password" {send "$password\r"}
}
expect eof
[fenfa@centos ~]$ vim fenfa_key.sh
#!/bin/sh
. /etc/init.d/functions
for ip in `cat host.list`
do
expect fenfa.exp ~/.ssh/id_dsa.pub $ip >/dev/null 2>&1
if [ $? -eq 0 ];then
   action "$ip" /bin/true
 else
   action "$ip" /bin/false
fi
done 

执行脚本结果如下

[fenfa@centos ~]$ sh fenfa_key.sh
10.0.0.1                         [  OK  ]
10.0.0.2                         [  OK  ]

只需要将文件替换成你所需要分发的文件即可

前端反向代理及管理后台服务器的配置
前端nginx反向代理服务器配置
安装所需的依赖包

[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.gz
tar zxf nginx-1.12.1.tar.gz
cd nginx-1.12.1
./configure --prefix=/app/nginx-1.12.1
make && 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;
    }
}
