docker之创建MariaDB镜像的方法

一、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

									[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

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

4.安装mariadb服务

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

初始化mariadb

1	`[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 'kingsoft'

									[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 'kingsoft' with grant option;

									MariaDB [mysql]> update user set password=password('kingsoft') 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

主机登录验证

									[root@test01 ~]# yum -y install mariadb

									[root@test01 ~]# mysql -u root --port=13306 -p

									MariaDB [(none)]>

二、基于Dockerfile方式创建

设置创建目录和文件

									[root@test01 ~]# mkdir mariadb_dockerfile && cd mariadb_dockerfile

									[root@test01 mariadb_dockerfile]# touch db_init.sh 

									[root@test01 mariadb_dockerfile]# touch run.sh

编辑Dockerfile等文件

Dockerfile

									[root@test01 mariadb_dockerfile]# cat Dockerfile 

									#使用的基础镜像

									FROM centos:7.4.1708

									#添加作者信息

									MAINTAINER liuxin 842887233@qq.com

									#安装mariadb数据库

									RUN yum -y install mariadb-server

									#设置环境变量，便于管理

									ENV MARIADB_USER root

									ENV MARIADB_PASS kingsoft

									#让容器支持中文

									ENV LC_ALL en_US.UTF-8

									#初始化数据库

									ADD db_init.sh /root/db_init.sh

									RUN chmod 775 /root/db_init.sh

									RUN /root/db_init.sh

									#导出端口

									EXPOSE 3306

									#添加启动文件

									ADD run.sh /root/run.sh

									RUN chmod 775 /root/run.sh

									#设置默认启动命令

									CMD ["/root/run.sh"]

db_init.sh

									[root@test01 mariadb_dockerfile]# cat db_init.sh 

									#!/bin/bash

									mysql_install_db --user=mysql

									sleep 3

									mysqld_safe &

									sleep 3

									#mysqladmin -u "$MARIADB_USER" password "$MARIADB_PASS"

									mysql -e "use mysql; grant all privileges on *.* to '$MARIADB_USER'@'%' identified by '$MARIADB_PASS' with grant option;"

									h=$(hostname)

									mysql -e "use mysql; update user set password=password('$MARIADB_PASS') where user='$MARIADB_USER' and host='$h';"

									mysql -e "flush privileges;"

run.sh

									[root@test01 mariadb_dockerfile]# cat run.sh 

									#!/bin/bash

									mysqld_safe

创建镜像

1	`[root@test01 mariadb_dockerfile]# docker build -t liuxin/centos-mariadb:v1 ./`

创建容器

									[root@test01 mariadb_dockerfile]# docker run -d -p 13306:3306 liuxin/centos-mariadb:v1 /root/run.sh

									[root@test01 mariadb_dockerfile]# docker ps

									CONTAINER ID  IMAGE      COMMAND    CREATED    STATUS    PORTS      NAMES

									7743527ac603  liuxin/centos-mariadb:v1 "/root/run.sh"  5 seconds ago  Up 3 seconds  0.0.0.0:13306->3306/tcp nostalgic_mirzakhani

登录验证

									[root@test01 mariadb_dockerfile]# mysql -uroot -h 127.0.0.1 --port=13306 -p

									Enter password: 

									Welcome to the MariaDB monitor. Commands end with ; or \g.

									Your MariaDB connection id is 1

									Server version: 5.5.56-MariaDB MariaDB Server

									Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

									Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

									MariaDB [(none)]> exit
