Linux学习-docker部署LAMP

Posted 2021-11-08 丢爸

创建数据卷映射目录

[root@docker ~]# mkdir -p /opt/vol/mysql /opt/vol/html

启动基础镜像容器并挂载数据卷和ssh端口映射

[root@docker ~]# docker run -it --name='centos_lamp' -v /opt/vol/mysql:/var/lib/mysql -v /opt/vol/html:/var/www/html -p 2222:22 centos:6.10

优化容器yum源并安装软件

合并两个CentOS6ISO镜像文件，制作本地yum源

[root@1d325b66b13f /]# cd /etc/yum.repos.d
[root@1d325b66b13f yum.repos.d]# mkdir bak
[root@1d325b66b13f yum.repos.d]# mv *.repo bak/
[root@1d325b66b13f yum.repos.d]# vi local.repo
[local]
name = linuxbase
baseurl = ftp://192.168.88.101/centos6new
gpgcheck = 0
enabled = 1
#更新yum本地缓存
[root@1d325b66b13f yum.repos.d]# yum makecache
#安装sshd
[root@1d325b66b13f yum.repos.d]# yum install -y openssh-server
#给root用户设置密码
[root@1d325b66b13f yum.repos.d]# echo "123456" | passwd --stdin root
#生成密钥文件
[root@6224937c547c yum.repos.d]# /etc/init.d/sshd start

#安装httpd,mysql,php
[root@6224937c547c yum.repos.d]# yum install -y httpd mysql-server php php-mysql
#启动mysql-server
[root@6224937c547c yum.repos.d]# /etc/init.d/mysqld start
Initializing MySQL database:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h 6224937c547c password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!
