docker部署mysql主从
如题
1.拉取镜像
docker pull mysql:5.7
2.创建目录
mkdir -p /opt/mysql/data
mkdir -p /opt/mysql/log
mkdir -p /opt/mysql/conf
chmod 777 -R /opt/mysql/log
3.创建mysql配置文件
vim /opt/mysql/conf/my.cnf
4.启动
docker run -dit -p 3306:3306 -e TZ=Asia/Shanghai --privileged=true --name mysql_master -v /opt/mysql/conf/my.cnf:/etc/my.cnf -v /opt/mysql/data:/var/lib/mysql -v /opt/mysql/log:/var/log/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
docker run -dit -p 3306:3306 -e TZ=Asia/Shanghai --privileged=true --name mysql_slave -v /opt/mysql/conf/my.cnf:/etc/my.cnf -v /opt/mysql/data:/var/lib/mysql -v /opt/mysql/log:/var/log/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
单节点
docker run -dit -p 3306:3306 -e TZ=Asia/Shanghai --privileged=true --name mysql -v /opt/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /opt/mysql/data:/var/lib/mysql -v /opt/mysql/log:/var/log/mysql -e MYSQL_ROOT_PASSWORD=thundersoft mysql:5.7
5.验证，数据目录，日志等
mysql -u -p
查看时区
select now();
show variables like '%time_zone%';
6.创建同步用户
create user 'repl'@'%' identified by 'repl';
grant replication slave,replication client on *.* to 'repl'@'%';
flush privileges;
7. 设置主主
show master status;
change master to
master_user='repl',
master_password='repl',
master_host='172.18.3.186',
master_log_file='mysql-bin.000003',
master_log_pos=782,
master_port=3306;
change master to
master_user='repl',
master_password='repl',
master_host='172.18.3.187',
master_log_file='mysql-bin.000003',
master_log_pos=782,
master_port=3306;
8.启动主从
start slave;
show slave status \G
更新
因为需要监控zabbix,需要获取mysqld.sock文件，因此进行更新
1.新建目录
mkdir -p /opt/mysql/run/mysqld
chown -R mysql.mysql /opt/mysql/run
chmod 777 -R /opt/mysql/run
2.配置文件更新，且挂载位置需要更新(注意配置文件)
2.1更新sock文件位置
启动挂载目录更新 /opt/mysql/conf/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
docker run -dit -p 3306:3306 --privileged=true --name mysql-master-new -v /opt/mysql/conf/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf -v /opt/mysql/data:/var/lib/mysql -v /opt/mysql/log:/var/log/mysql -v /opt/mysql/run/mysqld:/var/run/mysqld -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
