下面由centos教學欄位來介紹CentOS7系統初始化設定的方法,希望對需要的朋友有幫助!
CentOS7系統初始化設定
2019年03月07日
系統版本:CentOS Linux release 7.3-1611
使用nmtui 圖形工具設定IP位址和主機名稱
IP:192.168.82.103/24 主机名:leanote.jmkf.com
也可以變更設定檔
[root@leanote ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens32 TYPE=Ethernet BOOTPROTO=none 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=ens32 UUID=eb220f0e-779d-48c6-8e1b-093b2f9eff0f DEVICE=ens32 ONBOOT=yes IPADDR=192.168.55.58 PREFIX=24 IPADDR1=192.168.82.103 PREFIX1=24 GATEWAY=192.168.82.254 DNS1=192.168.94.201 IPV6_PEERDNS=yes IPV6_PEERROUTES=yes

# systemctl enable firewalld.service 启用 # systemctl disable firewalld.service 禁用
[root@leanote ~]# systemctl enable firewalld.service Created symlink from /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service to /usr/lib/systemd/system/firewalld.service.

[root@leanote ~]# setenforce 0 临时关闭
将SELINUX=enforcing 改为 SELINUX=disable#3.關閉SELINUX
[root@leanote ~]# vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. #SELINUX=enforcing SELINUX=disable # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted永久關機需要修改SELINUX的設定檔/etc/selinux/config
