docker之创建MariaDB镜像的方法

一、基于commit命令方式创建

docker的安装

?

1 2 3

[root@test01 ~] # yum install docker [root@test01 ~] # systemctl enable docker [root@test01 ~] # systemctl start docker

下载本地镜像

?

1 2 3 4

[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

?

1 2 3 4 5 6 7 8 9 10

[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

?

1 2 3 4 5 6 7 8 9 10

[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

?

1 2 3

[root@e8126d0481d2 /] # mysql -u root -h 172.17.0.2 -p Enter password: MariaDB [(none)]> exit

创建容器启动脚本

?

1 2 3 4

[root@e8126d0481d2 ~] # cat run.sh #!/bin/sh   mysqld_safe

创建镜像

?

1 2 3 4

[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

?

1 2 3 4

[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

?

1 2 3

[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

?

1 2 3

[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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

[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

?

1 2 3 4 5 6 7 8 9 10 11 12

[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

?

1 2 3

[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

?

1 2 3 4

[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

?

1 2 3 4 5 6 7 8 9 10 11

[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.
