在一些项目现场,很多时候,都是缺少专门的数据库运维人员的,但是开发人员开发项目,又需要用到MySQL数据库服务器,而且不同的项目的数据库又要分开
项目需求
对于非数据库运维人员,安装MySQL数据库有一定的难度,所以在这里推荐用Docker来搭建MySQL数据库服务。这种方案门槛低,对于非数据库专业人员也能秒级搭建好一条MySQL服务。
docker pull mysql:latest
直接执行这个命令,意思是拉取最新的镜像,但是实际项目可能需要制定的数据库版本,所以这里需要制定标签,拉取需要的镜像
docker pull mysql:5.7.28
拉取好镜像之后,就可以创建2个MySQL容器了,对外访问端口为3306,3307
[root@localhost ~]# docker run --name mysql5.7.28_3306 -e MYSQL_ROOT_PASSword=root -p 3306:3306 -d -it mysql:5.7.28
423e39a1c8669a53942aed14002102adbb8871c47edfbaa67825691eb16d0d45
[root@localhost ~]# docker run --name mysql5.7.28_3307 -e MYSQL_ROOT_PASSWORD=root -p 3307:3306 -d -it mysql:5.7.28
ff668e421d59b1fef61d58b70532bf87d5915da1c47d63db690857d74d283e12
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ff668e421d59 mysql:5.7.28 "docker-entrypoint.s鈥 29 seconds ago Up 27 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp mysql5.7.28_3307
423e39a1c866 mysql:5.7.28 "docker-entrypoint.s鈥 About a minute ago Up About a minute 0.0.0.0:3306->3306/tcp, 33060/tcp mysql5.7.28_3306
这样2个容器就创建好了,只是用docker ps显示的结果被截断了,不够友好,可以用下面的命令,来展示你需要看到的列信息就好
[root@localhost ~]# docker ps --format "table {{.ID}}t{{.Image}}t{{.Names}}t{{.Ports}}t{{.RunningFor}}t{{.Status}}"
CONTAINER ID IMAGE NAMES PORTS CREATED STATUS
ff668e421d59 mysql:5.7.28 mysql5.7.28_3307 33060/tcp, 0.0.0.0:3307->3306/tcp About a minute ago Up About a minute
423e39a1c866 mysql:5.7.28 mysql5.7.28_3306 0.0.0.0:3306->3306/tcp, 33060/tcp 2 minutes ago Up 2 minutes
验证端口
[root@localhost ~]# netstat -an|egrep "3306|3307"
tcp6 0 0 :::3306 :::* LISTEN
tcp6 0 0 :::3307 :::* LISTEN
可以看到,3306和3307端口已经开启。
MySQL客户端连接测试
[mysql@localhost ~]$ mysql -uroot -proot -h 192.168.17.128 -P 3306

[mysql@localhost ~]$

可以看到,两个MySQL数据库服务已经搭建好了,整个搭建都不到1分钟。
