MySQL8.0安装

Posted 2020-12-14 从此重新定义啦

1.卸载系统自带的mysql

rpm -qa|grep mysql
rpm -e --nodeps *mysql*
rpm -qa|grep mariadb
rpm -e --nodeps mariadb

2.安装MySQL8.0

 wget https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.15-linux-glibc2.12-x86_64.tar
tar -xvf mysql-8.0.15-linux-glibc2.12-x86_64.tar
 rm -f mysql-8.0.15-linux-glibc2.12-x86_64.tar
 xz -d mysql-8.0.15-linux-glibc2.12-x86_64.tar.xz
tar -xvf mysql-8.0.15-linux-glibc2.12-x86_64.tar 
mv mysql-8.0.15-linux-glibc2.12-x86_64 /usr/local/mysql
mkdir /data/mysql3306 -p

3.配置环境变量

vim /etc/profile
PATH=$PATH:/usr/local/mysql/bin

4.创建用户组并授权目录

groupadd mysql
useradd -r -g mysql -s /bin/false mysql
chown mysql.mysql -R /usr/local/mysql
chown mysql.mysql -R /data/mysql3306/

5.编辑配置文件
