解压安装包

cd /usr/local

tar xvf mysql-8.0.12-linux-glibc2.12-x86_64.tar.xz

mv mysql-8.0.12-linux-glibc2.12-x86_64 mysql

cd mysql/

mkdir conf

export PATH=$PATH:/usr/local/mysql/bin

实例1配置文件 my00.cnf

[mysqld]

basedir=/usr/local/mysql

datadir=/var/lib/mysql00

socket=/tmp/mysql00.sock

symbolic-links=0

port=3306

mysqlx_port=33060

[mysqld_safe]

log-error=/var/log/mysqld00.log

datadir=/var/lib/mysql01

socket=/tmp/mysql01.sock

symbolic-links=0

port=3307

mysqlx_port=33070

[mysqld_safe]

log-error=/var/log/mysqld01.log

pid-file=/var/lib/mysql01/mysqld.pid

实例3配置文件 my02.cnf

[mysqld]

basedir=/usr/local/mysql

datadir=/var/lib/mysql02

socket=/tmp/mysql02.sock

symbolic-links=0

port=3308

mysqlx_port=33080

[mysqld_safe]

log-error=/var/log/mysqld02.log

pid-file=/var/lib/mysql02/mysqld.pid

初始化实例

mysqld --defaults-file=/usr/local/mysql/conf/my00.cnf --initialize --user=mysql

mysqld --defaults-file=/usr/local/mysql/conf/my01.cnf --initialize --user=mysql

mysqld --defaults-file=/usr/local/mysql/conf/my02.cnf --initialize --user=mysql

启动实例

mysqld_safe --defaults-file=/usr/local/mysql/conf/my00.cnf --user=mysql &

mysqld_safe --defaults-file=/usr/local/mysql/conf/my01.cnf --user=mysql &

mysqld_safe --defaults-file=/usr/local/mysql/conf/my02.cnf --user=mysql &

修改密码

mysql -S /tmp/mysql00.sock -u root -p

ALTER USER root@'localhost' IDENTIFIED BY 'MySQL8.0';

mysql -S /tmp/mysql01.sock -u root -p

ALTER USER root@'localhost' IDENTIFIED BY 'MySQL8.0';

mysql -S /tmp/mysql02.sock -u root -p

ALTER USER root@'localhost' IDENTIFIED BY 'MySQL8.0';

关闭实例

mysqladmin -S /tmp/mysql00.sock -u root -pMySQL8.0 shutdown

mysqladmin -S /tmp/mysql01.sock -u root -pMySQL8.0 shutdown

mysqladmin -S /tmp/mysql02.sock -u root -pMySQL8.0 shutdown

注意：账号 root@'locahost' 使用 socket 连接数据库
