docker部署mysql 5.7.30（支持arm64和amd64）

1、mysql 安装（支持arm64和amd64）

mkdir /data/mysql/{etc,data,log} -p
chown 999  /data/mysql/log

cat >/data/mysql/etc/my.cnf << 'EOF'

2、主备配置

主节点：

#进入mysql-server容器中
docker exec -it mysql-server mysql -uroot -pMysql123456 
#设置主备同步的专用帐号
GRANT REPLICATION SLAVE ON *.* TO 'repl_user'@'%'  IDENTIFIED BY 'mysql_password';
flush privileges;
#查询主库状态
show master status;
mysql>  show master status

+------------------+----------+--------------+------------------+------------------------------------------+

备库节点：

#进入mysql-server容器中
docker exec -it mysql-server mysql -uroot -pMysql123456
#停止主从同步
stop slave;
#设置主节点
CHANGE MASTER TO 
MASTER_HOST='192.168.11.194',

3、phpmyadmin安装（支持arm64和amd64）

mkdir /data/myadmin
cat > /data/myadmin/start.sh << 'EOF'
docker rm -f  myadmin
docker run -d \
--restart=always \
