This article will explain in detail how to create a MariaDB image in docker. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

First, based on commit command to create

Installation of docker

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

Download the local image

[root@test01 ~] # docker pull centos:7.4.1708 [root@test01 ~] # docker images REPOSITORY TAG IMAGE ID CREATED SIZEdocker.io/centos 7.4.1708 3afd47092a0e 3 months ago 196.6 MB

Create an interactive container

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

4. Install the mariadb service

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

Initialize mariadb

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

Start the mariadb service in the background

[root@e8126d0481d2 /] # mysqld_safe & [1] 114 [root@e8126d0481d2 /] # 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-tunplActive Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 00.0.0.0root@e8126d0481d2 3306 0.0.0.0root@e8126d0481d2-

Create a mariadb login password and specify an ip login

[root@e8126d0481d2 /] # mysqladmin-u root password 'kingsoft' [root@e8126d0481d2 /] # mysql-u root-pEnter 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

Container login verification

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

Create a container startup script

[root@e8126d0481d2 ~] # cat run.shrun.shrunxxxxxxxxxxxxxxxxxxxxx

Create a mirror

[root@test01 ~] # docker ps-aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESe8126d0481d2 centos "/ bin/bash" 11 minutes ago Exited (0) 8 seconds ago mysql_ server [root @ test01 ~] # docker commit mysql_server mariadb:1.0

Create a container

[root@test01] # docker run-d-p 13306 mariadb:1.0 / root/run.sh [root@test01 ~] # docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESeed3e88a1261 mariadb:1.0 "mysqld_safe" 4 seconds ago Up 3 seconds 0.0.0.0 mariadb:1.0 13306-> 3306/tcp romantic_hamilton

Host login verification

[root@test01 ~] # yum-y install mariadb [root@test01 ~] # mysql-u root-- port=13306-pMariaDB [(none)] >

Second, create based on Dockerfile.

Set up creation directories and files

[root@test01 ~] # mkdir mariadb_dockerfile & & cd mariadb_ docker [root @ test01 mariadb_dockerfile] # touch db_init.sh [root@test01 mariadb_dockerfile] # touch run.sh

Edit files such as Dockerfile

Dockerfile

[root@test01 mariadb_dockerfile] # cat Dockerfile # basic image FROM centos:7.4.1708# used to add author information MAINTAINER liuxin 842887233@qq.com# install mariadb database RUN yum-y install mariadb-server# set environment variable Easy to manage ENV MARIADB_USER rootENV MARIADB_PASS kingsoft# let the container support Chinese ENV LC_ALL en_US.UTF-8# initialization database ADD db_init.sh / root/db_init.shRUN chmod 775 / root/db_init.shRUN / root/db_init.sh# export port EXPOSE 330 add startup file ADD run.sh / root/run.shRUN chmod 775 / root/run.sh# setting default startup command CMD ["/ root/run.sh"]

Db_init.sh

[root@test01 mariadb_dockerfile] # cat db_init.sh #! / bin/bashmysql_install_db-- user=mysqlsleep 3mysqld_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;" hype $(hostname) mysql-e "use mysql; update user set password=password ('$MARIADB_PASS') where user='$MARIADB_USER' and host='$h';" mysql-e "flush privileges;"

Run.sh

[root@test01 mariadb_dockerfile] # cat run.sh #! / bin/bashmysqld_safe

Create a mirror

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

Create a container

[root@test01 mariadb_dockerfile] # docker run-d-p 13306 liuxin/centos-mariadb:v1 / root/run.sh [root@test01 mariadb_dockerfile] # docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES7743527ac603 liuxin/centos-mariadb:v1 "/ root/run.sh" 5 seconds ago Up 3 seconds 0.0.0.0 liuxin/centos-mariadb:v1 13306-> 3306/tcp nostalgic_mirzakhani

Login authentication
