Linux安装MySQL脚本

centos系统非root用户安装mysql脚本文件

#!/bin/sh
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
##解压
tar -xvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz -C ~/
cd ~
mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql
#
###建好配置文件与mysql数据存储目录
mkdir /home/$USER/mysql/data
mkdir /home/$USER/mysql/conf

#echo $USER

##将sock文件链接到/tmp目录，默认mysql是读/tmp下的
ln -s /home/$USER/mysql/data/mysql.sock /tmp/mysql.sock

sh mysql_start

#初始化数据库
mysqld --defaults-file=/home/$USER/mysql/conf/my.cnf --user=$USER --initialize


#启动数据库
/home/$USER/mysql/bin/mysqld_safe --defaults-file=/home/$USER/mysql/conf/my.cnf --user=$USER &

#mysqladmin -u root -p password "root"
#mysql -uroot -proot
#更改密码为root
#set password for [email protected] = password("root")
