Linux下安装mysql-8.0.15

1、下载安装文件

wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.15-linux-glibc2.12-x86_64.tar.xz

 

2、解压安装文件

tar xf mysql-8.0.15-linux-glibc2.12-x86_64.tar.xz 

迁移至 /usr/local/mysql 目录下

 

3、创建mysql用户

useradd mysql

 

4、配置环境变量

vim /etc/profile

source /etc/profile

export MYSQL_HOME=/usr/local/mysql

export PATH=$MYSQL_HOME/bin:$PATH

 

5、修改my.cnf

配置 

basedir = /home/mysql

datadir = /home/mysql/data/

innodb_undo_directory = /home/mysql/undo_log

 log_error                      = /home/mysql/sql_log/mysql-error.log

 

6、初始化

mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/data

 

7、启动

mysqld start

查看初始密码

grep password mysql-error.log 

修改root密码

alter user user() identified by '123456'

创建普通用户

CREATE USER abc IDENTIFIED BY '1234567';    

GRANT ALL PRIVILEGES ON abc.* TO 'abc'@'%';

flush privileges;  

 

8、附my.cnf文件
