Linux環境使用Shell指令碼安裝Mysql5.6
1. 前言
之前在Linux上安裝Mysql總是花費很多時間，一行一行執行命令，很是繁瑣，所以決定寫個指令碼提升下效率，這個指令碼是基於Mysql5.6版本寫的，後續版本不適用，但是如果自己能看懂指令碼的可以稍加修改，如果有需要其他版本的自己又不是很熟悉Shell指令碼的留言給我。
2. 準備工作
到Mysql官網或者到華為軟體倉庫去下載Mysql安裝包
官網連結：https://dev.mysql.com/downloads/mysql/5.6.html#downloads
有32位和64位的區分 ，根據需要下載
華為軟體倉庫：https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-5.6/
我下載的版本是mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz
下載好安裝包後拷貝到Linux伺服器的任意位置上
檢查機器上是否安裝autoconf，執行命令：rpm -qa|grep autoconf
若無如上輸出，則執行命令安裝：yum -y install autoconf
3. 配置指令碼
指令碼內容如下
#!/bin/bash
# Mysql安裝包所在路徑,需要帶上包名，示例：PACKAGE_FULL_WAY=/root/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz

使用root使用者登入Linxu伺服器，在任意目錄下執行命令
vim mysql_manager.sh
按一下insert鍵，複製以上的指令碼內容，在機器上右鍵貼上進去
複製完成後需要修改指令碼最上方的三個配置項
|
PACKAGE_FULL_WAY |
Mysql安裝包所在路徑,需要帶上包名 示例：PACKAGE_FULL_WAY=/root/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz |
|
INSTALL_HOME |
Mysql安裝主目錄 示例：INSTALL_HOME=/usr/local/mysql |
|
USER_PASSWD |
Mysql資料庫root使用者密碼 示例：USER_PASSWD=root |
修改完成後按一下Esc鍵，鍵盤輸入:wq!即可
指令碼命令：
|
sh mysql_manager.sh install |
安裝並啟動Mysql |
|
sh mysql_manager.sh start |
啟動Mysql |
|
sh mysql_manager.sh stop |
關閉Mysql |
|
sh mysql_manager.sh restart |
重啟Mysql |
|
sh mysql_manager.sh check_status |
Mysql狀態檢查 |
|
sh mysql_manager.sh uninstall |
解除安裝Mysql |
