初始化centos环境

1 软件安装

yum install -y wget 
如果需要安装nginx，需要先安装epel
wget https://mirrors.ustc.edu.cn/epel//7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
下载完成后安装 rpm -ivh epel-release-7-11.noarch.rpm
##  依次为 nginx redis docker 防火墙 git
yum install -y nginx redis docker iptables iptables-services  git
## 启动防火墙 
service iptables start
## 动态添加访问port 
iptables -I INPUT -p tcp --dport 8008 -j ACCEPT
## 配置文件添加 /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 2183 -j ACCEPT
## 保存规则到配置文件
service iptables save 
## 查看iptables状态
service iptables status
##配置git
ssh-keygen -t rsa -C 'xieyue86@163.com'  -f  gitee_id_rsa
