docker之创建MariaDB镜像的方法

基于commit命令方式创建

docker的安装

[root@test01 ~]# yum install docker

[root@test01 ~]# systemctl enable docker

[root@test01 ~]# systemctl start docker

下载本地镜像

[root@test01 ~]# docker pull centos:7.4.1708

 或本地镜像docker pull centos 会pull最新本                         

[root@test01 ~]# docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

docker.io/centos    7.4.1708            3afd47092a0e        3 months ago        196.6 MB

创建交互型容器

[root@test01 ~]# docker run -it --name="mysql_server" centos /bin/bash

安装mariadb服务

[root@e8126d0481d2 /]# yum -y install mariadb-server net-tools

初始化mariadb

[root@e8126d0481d2 /]# mysql_install_db --user=mysql

后台启动mariadb服务

[root@e8126d0481d2 /]# mysqld_safe &

[1] 114

[root@e8126d0481d2 /]#

180210 13:45:27 mysqld_safe Logging to '/var/log/mariadb/mariadb.log'.

180210 13:45:27 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

 

[root@e8126d0481d2 /]# netstat -tunpl

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      -

创建mariadb登录密码，并可以指定ip登录

[root@e8126d0481d2 /]# mysqladmin -u root password '123456'

[root@e8126d0481d2 /]# mysql -u root -p

Enter password:

MariaDB [(none)]> show databases;

MariaDB [(none)]> use mysql;

MariaDB [mysql]> select Host from user where user='root';

MariaDB [mysql]> grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

MariaDB [mysql]> update user set password=password('123456') where user='root' and host='e8126d0481d2';

MariaDB [mysql]> flush privileges;

MariaDB [mysql]> exit

容器登录验证

[root@e8126d0481d2 /]# mysql -u root -h 172.17.0.2 -p

Enter password:

MariaDB [(none)]> exit

创建容器启动脚本

[root@e8126d0481d2 ~]# cat run.sh

#!/bin/sh

mysqld_safe

创建镜像

[root@test01 ~]# docker ps -a

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES

e8126d0481d2        centos              "/bin/bash"         11 minutes ago      Exited (0) 8 seconds ago                       mysql_server

[root@test01 ~]# docker commit mysql_server mariadb:1.0

创建容器

[root@test01 ~]# docker run -d -p 13306:3306 mariadb:1.0 /root/run.sh

[root@test01 ~]# docker ps

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                     NAMES

eed3e88a1261        mariadb:1.0         "mysqld_safe"       4 seconds ago       Up 3 seconds        0.0.0.0:13306->3306/tcp   romantic_hamilton

 

进入容器

docker exec -ti -u root romantic_hamilton  bash

主机登录验证
