本篇内容介绍了“MySQL 自动安装脚本分享”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让丸趣 TV 小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
环境要求：centos：6.8
MySQL：5.7.20
MySQL 安装文件名：mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
MySQL 源文件路径：/usr/local/src
MYSQL 脚本文件：/usr/local/src/install_mysql.sh
1、脚本如下：
#/bin/sh
#px 2017-11-29
#mysql install
#email:kitten-pan@163.com 752684428
#version 2.0
#mysql-version mysql5.7.20
source_path=/usr/local/src
install_path=/usr/local/mysql
install_name=mysql-5.7.20-linux-glibc2.12-x86_64
## 检测本机环境
env_fun()
{
echo ============ 检测本机环境,please wait …
username=`cat /etc/passwd |grep mysql|cut -c 1-5`
if [$username = mysql];then
echo MySQL account is exits…
return 10
else
echo mysql account is not exits,ready add…
groupadd mysql
useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql
return 12
fi
}
## 判断 MySQL 是否安装
check_fun()
{
rpm_name=`rpm -aq |grep mysql-server`
echo $rpm_name
if [! $rpm_name];then
echo begin check the source install,please wait for a moment…
if [-d $install_path];then
echo source install is exist,quit…
exit 0
else
echo 本机未安装 MySQL, 稍后为你安装 …
install_fun
op_fun
fi
else
echo -n rpm MySQL 已经安装，是否删除？[yes|no]
read select
if [$select = yes];then
rpm -e $rpm_name –nodeps
rm -rf /var/log/mysqld.log
check_fun
else
exit 0
fi
fi
}
### 安装 MySQL
install_fun()
{
read -p Input a mysql version: -t 30 mysql_version
read -p Input a mysql port: -t 30 mysql_port
read -p Input a mysql_server_id: -t 30 mysql_server_id
cd $source_path echo 解压中,please waiting…
tar -zxvf ${install_name}.tar.gz mv $install_name $install_path
## 创建数据目录
mkdir -pv /data/mysqldata
### 给 MySQL 目录的 MySQL 账号权限
cd /usr/local chown mysql.mysql mysql
chown -R mysql.mysql /data/mysqldata
cd $install_path bin/mysqld –initialize –user=mysql –basedir=/usr/local/mysql –datadir=/data/mysqldata
cd support-files cp -rf mysql.server /etc/init.d/mysqld

2、执行自动安装脚本
需要填写 MySQL 的版本信息、端口信息、serverid 信息等
点击 (此处) 折叠或打开
sh install_mysql.sh
###==================================================###
###welcome to make install mysql with this script###
###copyright 2013 by px###
###==================================================###
============ 检测本机环境,please wait …
mysql account is not exits,ready add…
begin check the source install,please wait for a moment…
本机未安装 MySQL, 稍后为你安装 …
Input a mysql version:5.7.20
Input a mysql port:3309
Input a mysql_server_id:1
解压中,please waiting…
3、自动安装完毕 启动
# service mysqld restart
MySQL server PID file could not be found! [FAILED]
Starting MySQL…………. [ OK ]
4、登入 MySQL 修改密码
点击 (此处) 折叠或打开
[root@ct562 mysqldata]# mysql -uroot -p
Enter password:
