Deploy MySQL and Wordpress under Docker
Check the current system version. Docker requires that CentOS must be at least 64 bit 7 version:
1. [ root@localhost ~]# cat /etc/redhat-release
2. CentOS Linux release 7.6.1810 (Core)
Check the kernel version. Docker supports kernel version 3.10 or above:
1. [ root@localhost ~]# uname -r
2. 3.10.0-957.el7.x86_64
Install Docker
1. [ root@localhost ~]# yum install -y docker
In order to speed up the download of Docker, we usually download from domestic image sites. Modify the mirror server
Open Profile
1. [ root@localhost ~]# cd /etc/docker
2. [ root@localhost docker]# vi daemon.json
To modify the content of the configuration file, select the AliCloud image site here:
1. {
2. "registry-mirrors": [" //6xacs6l2.mirror.aliyuncs.com "]
3. }
Start Docker service
1. [ root@localhost docker]# systemctl start docker.service
