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

exit 0
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:
