一、初始化centos系統指令碼

setenforce 0

sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config

systemctl stop NetworkManager

systemctl disable NetworkManager

systemctl status firewalld

systemctl stop firewalld

systemctl disable firewalld

systemctl status firewalld

firewall-cmd --state

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

yum clean all && yum makecache

yum update -y

二、國內源docker安裝指令碼

curl -sSL https://get.daocloud.io/docker | sh -s -- "--mirror" "Aliyun"

mkdir -p /etc/docker

cat > /etc/docker/daemon.json <<EOF

{

"registry-mirrors": ["https://6m7d428u.mirror.aliyuncs.com"],

"dns": ["114.114.114.114"],

"exec-opts": ["native.cgroupdriver=systemd"],

"log-driver": "json-file",

"log-opts": {

"max-size": "100m"

},

"storage-driver": "overlay2",

"storage-opts": [

"overlay2.override_kernel_check=true"

]

}

EOF

systemctl enable docker && systemctl daemon-reload && systemctl restart docker

curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

三、拉取MySQL映象

MySQL映象地址（選擇自己需要安裝的版本）：

https://hub.docker.com/_/mysql?tab=tags&page=1&ordering=last_updated

拉取命令：docker pull mysql:5.7.33

四、啟動容器

docker run -itd --name mysql-test -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.33

可以打下 docker images 看到當前拉取的映象

然後執行 docker run -itd --name mysql-test -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.33

mysql-test 是這個新建的容器的名稱 -p 3306:3306 是將容器內mysql預設要使用的3306的埠對映到當前虛擬機器的3306埠上

MYSQL_ROOT_PASSWORD=123456 是為安裝的mysql5.7.33設定預設的root賬戶的密碼 mysql:5.7.33是當前容器要用到的映象的名稱
