1、官网下载mysql安装包

? ? ? ?https://downloads.mysql.com/archives/community/?

2、解压安装包

tar  -zxvf  mysql-8.1.0-linux-glibc2.28-aarch64.tar.xz  -C  /usr/local

mv  /usr/local/mysql-8.1.0-linux-glibc2.28-aarch64   /usr/local/mysql

3、创建mysql用户组

  groupadd mysql

  ueradd -r -g mysql mysql

  chmod  ug+rwx /data/mysql/*
  
  chown mysql:mysql -R /data/mysql/*

?4、创建数据存储目录

mkdir  -p  /data/mysql/3310

mkdir  -p  /data/mysql/3311

5、初始化数据库

/usr/local/mysql/bin/mysqld --initialize-insecure --datadir=/data/mysql/3310/data --user=mysql
/usr/local/mysql/bin/mysqld --initialize-insecure --datadir=/data/mysql/3311/data --user=mysql

6、实例启动配置文件

? ? 3310的配置

cat >>   /data/mysql/3311/my.cnf  <<   EOF

[mysqld]
bind-address=0.0.0.0
port=3310
basedir=/usr/local/mysql
datadir=/data/mysql/3310/data
socket=/data/mysql/3310/mysql.sock
log-bin=/data/mysql/3310//data/mysql-bin
server-id=3310

[mysqld_safe]
log-error=/data/mysql/3310/mysqld_error.log
pid-file=/data/mysql/3310/mysqld.pid

EOF

? 3311的配置

cat  >>  /data/mysql/3311/my.cnf  << 

[mysqld]
bind-address=0.0.0.0
port=3311
basedir=/usr/local/mysql
datadir=/data/mysql/3311/data
socket=/data/mysql/3311/mysql.sock
log-bin=/data/mysql/3311//data/mysql-bin
server-id=3311

[mysqld_safe]
log-error=/data/mysql/3311/mysqld_error.log
pid-file=/data/mysql/3311/mysqld.pid

EOF

7、启动数据库实例

? ? 启动3310

/usr/local/mysql/bin/mysqld_safe  --defaults-file=/data/mysql/3310/my.cnf   2>&1 > /var/log/mysql3310.log  &

? ?启动3311

/usr/local/mysql/bin/mysqld_safe  --defaults-file=/data/mysql/3311/my.cnf   2>&1 > /var/log/mysql3311.log  &

? ?检测启动状态

ps -ef  | grep  msyqld

8、客户端连接测试

 /usr/local/mysql/bin/mysql  -h  127.0.0.1  -P 3310  -u root
 /usr/local/mysql/bin/mysql  -h  127.0.0.1  -P 3311  -u root

? 设置root密码

 update user set   authentication_string="root!2018LC"  where user="root"
