1. 前言

之前在Linux上安装Mysql总是花费很多时间，一行一行执行命令，很是繁琐，所以决定写个脚本提升下效率，这个脚本是基于Mysql5.6版本写的，后续版本不适用，但是如果自己能看懂脚本的可以稍加修改，如果有需要其他版本的自己又不是很熟悉Shell脚本的留言给我。

2. 准备工作

到Mysql官网或者到华为软件仓库去下载Mysql安装包

官网链接：https://dev.mysql.com/downloads/mysql/5.6.html#downloads

有32位和64位的区分，根据需要下载

华为软件仓库：https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-5.6/

我下载的版本是mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz

下载好安装包后拷贝到Linux服务器的任意位置上

3. 配置脚本

脚本内容如下

#!/bin/bash

# Mysql安装包所在路径,需要带上包名，示例：PACKAGE_FULL_WAY=/root/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz

PACKAGE_FULL_WAY=

# Mysql安装主目录,示例：INSTALL_HOME=/usr/local/mysql

INSTALL_HOME=

# Mysql数据库root用户密码,示例：USER_PASSWD=root

USER_PASSWD=

#check user

if [[ "$UID" -ne 0 ]]; then

echo "ERROR: the script must run as root"

exit 3

function LOG_INFO()

{

echo "[$(date -d today +"%Y-%m-%d %H:%M:%S %:::z")] $1"

}

function LOG_ERROR()

{

echo -e "[$(date +"%Y-%m-%d %H:%M:%S %Z%:z")] [ERROR] $* \n"

exit 1

}

CHECK_RESULT()

{

RETCODE=$1

shift

ERROR_MSG=$*

if [[ ${RETCODE} -ne 0 ]]; then

LOG_ERROR ${ERROR_MSG}

}

# 校验参数

function CHECK_PARAM()

{

if [[ ! -n ${PACKAGE_FULL_WAY} ]] || [[ ! -n ${INSTALL_HOME} ]] || [[ ! -n ${USER_PASSWD} ]]; then

LOG_ERROR "Param: PACKAGE_FULL_WAY INSTALL_HOME USER_PASSWD can not be null"

if [[ ! -f ${PACKAGE_FULL_WAY} ]]; then

LOG_ERROR "Please check the config of PACKAGE_FULL_WAY dose config Mysql package name"

}

function CHECK_MYSQL_PROCESS()

{

local mysql_process_count=`ps -ef |grep ${INSTALL_HOME}|grep -v grep|wc -l`

if [[ ${mysql_process_count} -gt 0 ]]; then

LOG_ERROR "please stop and uninstall the mysql first"

}

# 新建mysql用户

function ADD_USER()

{

#create group mysql

grep "^mysql" /etc/group &> /dev/null

if [[ $? -ne 0 ]]; then

groupadd mysql

#create user mysql

if [[ $? -ne 0 ]]; then

useradd -g mysql mysql

chage -M 99999 mysql

}

# 安装Mysql

function INSTALL_MYSQL()

{

# 创建安装主目录

mkdir -p ${INSTALL_HOME}

# 解压mysql到安装主目录

tar -zxvf ${PACKAGE_FULL_WAY} -C ${INSTALL_HOME} > /dev/null 2>&1

# 安装并指定用户和data文件夹位置

./scripts/mysql_install_db --user=mysql --datadir=${INSTALL_HOME}/data/mysql

#chown -R root:root ./

#chown -R mysql:mysql data

# 复制mysql到服务自动启动里面

cp -pf ${INSTALL_HOME}/support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

# 复制配置文件到etc下

cp -pf ${INSTALL_HOME}/support-files/my-default.cnf /etc/my.cnf

chmod 755 /etc/my.cnf

# 修改basedir和datadir

sed -i "s#^basedir=.*#basedir=${INSTALL_HOME}#" /etc/init.d/mysqld

sed -i "s#^datadir=.*#datadir=${INSTALL_HOME}\/data\/mysql#" /etc/init.d/mysqld

# 加入环境变量,方便使用mysql命令,但是需要source /etc/profile

echo "###MYSQL_PATH_ENV_S" >>/etc/profile

echo "export PATH=${INSTALL_HOME}/bin:\$PATH" >> /etc/profile

echo "###MYSQL_PATH_ENV_E" >> /etc/profile

# 启动Mysql

# 修改Mysql用户root密码

./bin/mysqladmin -u root -h localhost.localdomain password ${USER_PASSWD}

cd ${INSTALL_HOME}

# 开启远程登录权限

./bin/mysql -h127.0.0.1 -uroot -p${USER_PASSWD} << EOF

grant all privileges on *.* to root@'%' identified by 'root'; flush privileges;

EOF

}

# 卸载Mysql

local mysql_process_count=`ps -ef |grep ${INSTALL_HOME}|grep -v grep|wc -l`

if [[ ${mysql_process_count} -gt 0 ]]; then

stop

# 删除创建的文件

rm -rf ${INSTALL_HOME}

rm -rf /etc/init.d/mysqld

rm -rf /etc/my.cnf

# 删除配置的环境变量

sed -i '/###MYSQL_PATH_ENV_S/,/###MYSQL_PATH_ENV_E/d' /etc/profile

#删除用户和用户组

if [[ $? -eq 0 ]]; then

}

# 停止Mysql

{

function usage() {

使用root用户登录Linxu服务器，在任意目录下执行命令

vim mysql_manager.sh

按一下insert键，复制以上的脚本内容，在机器上右键粘贴进去

复制完成后需要修改脚本最上方的三个配置项

PACKAGE_FULL_WAY

Mysql安装包所在路径,需要带上包名

示例：PACKAGE_FULL_WAY=/root/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz

INSTALL_HOME

Mysql安装主目录

示例：INSTALL_HOME=/usr/local/mysql

USER_PASSWD

Mysql数据库root用户密码

示例：USER_PASSWD=root

修改完成后按一下Esc键，键盘输入:wq!即可

脚本命令：

sh mysql_manager.sh install	安装并启动Mysql
sh mysql_manager.sh start	启动Mysql
sh mysql_manager.sh stop	关闭Mysql
sh mysql_manager.sh restart	重启Mysql
sh mysql_manager.sh check_status	Mysql状态检查
sh mysql_manager.sh uninstall	卸载Mysql

如果有Shell脚本大神觉得写得不对的地方请留言指正
