1、网络配置 1.1动态获取IP dhclient 1.2静态IP 修改/etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
**BOOTPROTO=static**
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=47142241-91cf-415e-81bb-4cfa6e7f2494
DEVICE=ens33
**ONBOOT=yes**
**IPADDR=192.168.48.110
NETMASK=255.255.255.0
GATEWAY=192.168.48.2***
2、ifconfig命令找不到
yum search ifocnfig
yum install net-tools.x86_64
3、查看开启的端口 netstat -ntlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 1003/redis-server 1
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 991/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1186/master
tcp6 0 0 :::22 :::* LISTEN 991/sshd
tcp6 0 0 :::23 :::* LISTEN 1/systemd
tcp6 0 0 ::1:25 :::* LISTEN 1186/master
4、防火墙打开端口 firewall-cmd --zone=public --add-port=6379/tcp --permanent 开端口命令:firewall-cmd --zone=public --add-port=80/tcp --permanent 重启防火墙:systemctl restart firewalld.service 命令含义: --zone #作用域 --add-port=80/tcp #添加端口,格式为:端口/通讯协议 --permanent #永久生效,没有此参数重启后失效
5、查看防火墙允许访问的端口 firewall-cmd --list-ports
