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. 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.
