捡便宜买了一台新机器，需要配置一下环境。
虽然现在都用docker了，阿里云的k8s可以直接用，但是自己的单台服务器除了docker，php和niginx还是缺少不了。所以安装的是nginx+php+docker（mysql不装了，现在用云数据库，程序和数据彻底分开放了）
（除了php7.3 nginx docker，还有些必备的git，composer，docker-compose，node）
1准备
// 看下系统
# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
# yum remove httpd* php*
已加载插件：fastestmirror, langpacks
参数 httpd* 没有匹配
参数 php* 没有匹配
不删除任何软件包
2更新yum源
# cd /etc/yum.repos.d/
// 查看当前的repo有哪些
# ls -al
// 删除所有源
# rm -rf /etc/yum.repos.d/*.repo
// 下载阿里云源
# wget http://mirrors.aliyun.com/repo/Centos-7.repo
// 安装epel（epel才有nginx）
# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
// 安装remi才有php7
# yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
// 清理yum缓存
# yum clean all
已加载插件：langpacks, versionlock
正在清理软件源： base extras updates
Cleaning up everything
//makecache建立一个缓存，以后用install时就在缓存中搜索，提高了速度。
# yum makecache
已加载插件：langpacks, versionlock
.....
元数据缓存已建立
// 再次查看所有repo
# ls -al
# yum repolist
// 升级一下吧
# yum update
// 省略一万字 大概300多个更新，阿里云源下载每秒3m左右 很快
3安装nginx
# yum install nginx
// 输出省略一万字

# systemctl enable nginx.service // 设置开机启动
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
systemctl start nginx.service // 启动ngixn
此时打开你的ip，应该能看到wellcome to centos,如果没有，那就炸了，去看下安全组的端口是不是开了，
同时也看下其他端口，和安全组设置
4安装php

要好一会儿，装好后顺便装下docker-compose，也有非常清楚的安装文档，无脑粘贴命令就行
// 就是一个可执行文件 然后放在/usr/local/bin就能全局可用了
# curl -L "https://github.com/docker/compose/releases/download/1.25.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
// 如果太慢 试试 curl -L "https://get.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
// 添加执行权限
# chmod +x /usr/local/bin/docker-compose
