Linux系统集群架构线上项目配置实战教程（二），linux实战

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

[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  ]
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/

编写分发文件脚本

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 https://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 https://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 https://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

JDK Tomcat环境安装**

tar zxf apache-tomcat-8.5.9.tar.gz
mv apache-tomcat-8.5.9 /usr/local/tomcat
tar zxf jdk-8u111-linux-x64.tar.gz -C /usr/local/
cd /usr/local/
ln -s jdk1.8.0_111 jdk
cat >>/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 https://admin.mingongge.com
this is the admin.mingongge.com
[root@centos ~]# curl https://shangjia.mingongge.com
this is the shangjia.mingongge.com
