基於commit命令方式創建
docker的安裝
[root@test01 ~]# yum install docker [root@test01 ~]# systemctl enable docker [root@test01 ~]# systemctl start docker
下載本地鏡像
[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
創建交互型容器
[root@test01 ~]# docker run -it --name="mysql_server" centos /bin/bash
安裝mariadb服務
[root@e8126d0481d2 /]# yum -y install mariadb-server net-tools
初始化mariadb
[root@e8126d0481d2 /]# mysql_install_db --user=mysql
后台啟動mariadb服務
[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

創建mariadb登錄密碼，並可以指定ip登錄
[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
容器登錄驗證
[root@e8126d0481d2 /]# mysql -u root -h 172.17.0.2 -p Enter password: MariaDB [(none)]> exit
創建容器啟動腳本
[root@e8126d0481d2 ~]# cat run.sh #!/bin/sh
mysqld_safe
創建鏡像
[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
創建容器
[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
主機登錄驗證
[root@test01 ~]# yum -y install mariadb [root@test01 ~]# mysql -u root --port=13306 -p MariaDB [(none)]>
基於Dockerfile方式創建
設置創建目錄和文件 [root@test01 ~]# mkdir mariadb_dockerfile && cd mariadb_dockerfile [root@test01 mariadb_dockerfile]# touch db_init.sh [root@test01 mariadb_dockerfile]# touch run.sh
編輯Dockerfile等文件 Dockerfile [root@test01 mariadb_dockerfile]# cat Dockerfile
