如何搭建docker虚拟机测试服

docker run -itd --privileged=true -p 22000:22 -p 13306:3306 -p 16379:6379 --name mytest systemd:latest

#配置yum为阿里云的源
rm -rf /etc/yum.repos.d/*
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum repolist 
#查看linux时区
timedatectl
<strong>#设置时区为上海（中国标准时间）</strong>
sudo timedatectl set-timezone Asia/Shanghai
timedatectl
#虚拟机安装java
java -version
yum list java*jdk-devel
yum install java-1.8.0-openjdk-devel -y
#修改ls/ll显示的时间格式  2023/07/31 15:30:00
vi ~/.bash_profile
# 文件末尾添加
export TIME_STYLE='+%Y/%m/%d %H:%M:%S'
# 使配置立即生效
source ~/.bash_profile
#查看虚拟机的IP，通常是172.17.0.2
ifconfig
#查看运行程序的端口
yum install -y net-tools
netstat -nlpt
<strong>#安装ssh</strong>
yum install -y openssh-server
# 编辑 SSH 配置文件
vi /etc/ssh/sshd_config
#启动和设置开机启动
systemctl start sshd
systemctl enable sshd
systemctl status sshd
#重置root密码（是从容器进来的，本来密码不知道）
passwd root
#在实体机中测试虚拟机中的端口连接
ssh root@172.17.0.2
exit
<strong>#安装mysql</strong>
#！注意 yum install -y mariadb-server 安装的是mysql5.5，版本很低
#下载mysql源安装包
yum install -y wget
wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
rpm -ivh mysql57-community-release-el7-11.noarch.rpm
#--nogpgcheck    不校验数字签名
yum -y install mysql-server --nogpgcheck
#启动
systemctl start mysqld
systemctl enable mysqld
systemctl status mysqld
#MySQL 5.7 安装后会生成一个临时 root 密码：
cat /var/log/mysqld.log | grep password
mysql_secure_installation
#输入上面查到的默认密码，设置新密码（至少8位，必须包含 大小写字母、数字、特殊字符）
#进入mysql
mysql -p'密码'
show databases;
#开放root用户远程登录
UPDATE mysql.user SET Host='%' WHERE User='root' AND Host='localhost';
FLUSH PRIVILEGES;
quit
<strong>#安装redis</strong>
#Redis 不在默认的 CentOS 仓库中，需先添加 EPEL仓库
yum install -y epel-release
yum install -y redis
systemctl start redis
systemctl enable redis
systemctl status redis
#进入redis
redis-cli
SET hello world
GET hello
quit
#开放外部访问  vi /etc/redis.conf
# 注释掉bind（默认仅监听本地）
# bind 127.0.0.1
# 关闭保护模式
protected-mode no
# 设置密码
requirepass 密码
#然后重启redis
systemctl restart redis
<strong>#安装nginx</strong>
yum install -y nginx
systemctl start nginx
systemctl enable nginx
systemctl status nginx
#nginx配置文件在/etc/nginx/nginx.conf
#虚拟机中的nginx不需要https
#此镜像中没有防火墙，不需要打开防火墙端口
#firewall-cmd --permanent --add-port=22/tcp
#firewall-cmd --permanent --add-port=3306/tcp
#firewall-cmd --permanent --add-port=6379/tcp
#firewall-cmd --permanent --add-port=80/tcp
#firewall-cmd --reload
#清理yum的硬盘空间
yum clean all

telnet 172.17.0.2 3306
quit
telnet 172.17.0.2 6379
quit
telnet 172.17.0.2 80
quit
#开放防火墙端口
firewall-cmd --permanent --add-port=22000/tcp
firewall-cmd --permanent --add-port=13306/tcp
firewall-cmd --permanent --add-port=16379/tcp
firewall-cmd --reload

vi /etc/hosts
