Linux centos7 安装python3.6.3

一、配置防火墙，开启80端口、3306端口
CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。
1、关闭firewall：
[root@localhost ~]#systemctl stop firewalld.service      #停止firewall
[root@localhost ~]#systemctl disable firewalld.service #禁止firewall开机启动
2、安装iptables防火墙
[root@localhost ~]#yum install iptables-services          #安装
[root@localhost ~]#vi /etc/sysconfig/iptables                #编辑防火墙配置文件
[root@localhost ~]#Firewall configuration written by system-config-firewall
[root@localhost ~]#Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出
[root@localhost ~]#systemctl restart iptables.service    #最后重启防火墙使配置生效
[root@localhost ~]#systemctl enable iptables.service   #设置防火墙开机启动
二、关闭SELINUX
[root@localhost ~]#vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
三 、系统约定
软件源代码包存放位置：/usr/local/src
源码包编译安装位置：/usr/local/软件名字
