環境：centos

一：首先配置一個靜態ip地址：

這裡採用的是：NAT模式下的靜態IP
  1）虛擬機器聯網方式修改成NAT模式
  2）進入虛擬機器的 /etc/sysconfig/network-scripts目錄
          cd /etc/sysconfig/network-scripts
  3）編輯檔案     vi  ifcfg-ens33

修改：
     BOOTPROTO=static

     ONBOOT=yes

   3.2 查詢理主機的VM8的網段 cmd 下：ipconfig
   vmnet8: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 00:50:56:c0:00:08 
    inet 192.168.19.1 netmask 0xffffff00 broadcast 192.168.19.255

    則我的物理主機的VM8的網段：192.168.19

      3.3則ifcfg-ens33檔案中新增內容：最後新增以下內容
      注意：網段跟物理主機的VM8的網段一致
      IPADDR=192.168.19.26      //我們配置的靜態ip
      NETMASK=255.255.255.0 
      GATEWAY=192.168.19.2     // 最後一位都為2
      DNS1=192.168.19.2          // 跟GATEWAY一致即可。

 4.重啟閘道器   service network  restart

 5.ip addr

或者 ifconfig檢視ip是否變成我們配置的靜態ip地址

 6.ping www.baidu.com 檢視能否聯網。
 

 二、Linux下安裝5.6.42 MySQL Community Server (GPL)

首先進入要安裝的位置：我的是/opt/install

cd /opt

mkdir install

cd install

1) wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

如不能執行wget則，yum -y install wget

2) rpm -ivh mysql-community-release-el7-5.noarch.rpm

3) yum -y install mysql-server

[[email protected] install]# service mysqld restart               //重啟mysql     或者/etc/rc.d/init.d/mysqld start

Redirecting to /bin/systemctl restart mysqld.service

[[email protected] install]# mysql --version           

mysql  Ver 14.14 Distrib 5.6.42, for Linux (x86_64) using  EditLine wrapper

[[email protected] install]# mysql

如果mysql的客戶端連線不上則開放防火牆的埠

[[email protected] install]# firewall-cmd  --permanent --add-port=3306/tcp

success

[[email protected] install]# firewall-cmd  --permanent --add-port=22/tcp

success

[[email protected] install]# firewall-cmd  --permanent --add-port=8066/tcp

success

[[email protected] install]# firewall-cmd  --permanent --add-port=8080/tcp

success

[[email protected] install]# firewall-cmd  --permanent --add-port=8090/tcp

success

[[email protected] install]# firewall-cmd  --reload                      //記住一定要reload

success

其他設定:

檢視mysql開機自啟動設定情況

​ chkconfig mysqld on

（mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off）　 ← 如果2--5為on的狀態就OK

停止mysql:  service mysqld stop
