区别:一、centos7用systemd承办init;两、修正主机名, centos6需修正“/etc/sysconfig/network”,而7批改“/etc/hostname”;三、centos7用chrony号令异步功夫,6用ntp。
原学程垄断情况:centos7体系、thinkpad t480电脑。
比来正在运用CentOS 7,创造许多号召等以及CentOS 6纷歧样,以是那面列进去不便参考。
1、少用的systemctl号召
CentOS 7入手下手运用systemd来承办init 体系女过程,因而闇练systemctl颇有须要。
CentOS 7 | CentOS 6 | 做用 |
systemctl start sshd.service | service sshd start | 封动ssh就事 |
systemctl stop sshd.service | service sshd stop | 结束ssh管事 |
systemctl restart sshd.service | service sshd restart | 重封ssh办事 |
systemctl status sshd.service | service sshd status | 查望ssh任事形态 |
systemctl reload sshd.service | service sshd reload | 从新添载ssh管事 |
systemctl enable sshd.service | chkconfig --level 3 sshd on | 谢机自封动ssh管事 |
systemctl disable sshd.service | chkconfig --level 3 sshd off | 谢机禁行封动ssh做事 |
systemctl list-unit-files --type=service | chkconfig --list | 列没一切的办事形态 |
systemctl list-units | chkconfig --list、ntsysv | 列没容许外的处事单位 |
systemctl is-active sshd.service | chkconfig --list sshd | 查望ssh供职能否运转 |
systemctl mask sshd.service | 屏障(不克不及封用)ssh任事 | |
systemctl unmask sshd.service | 解搁屏障ssh管事 | |
systemctl show sshd.service | 表示SSH就事的设施疑息 | |
systemctl get-default | 猎取当前应用的运转品级 | |
systemctl set-default runlevel3.target | vi /etc/inittab | 批改默许的运转品级 |
systemctl isolate runlevel3.target | init 3 | 封用运转品级3 |
2、设备文件
一、封动装备
centos6:批改/etc/inittab
centos7:systemctl set-default runlevel3.target
两、修正主机名
centos6:修正/etc/sysconfig/network
centos7:批改/etc/hostname
三、封闭封动文件/etc/rc.d/rc.local
centos6:没有须要任何修正
centos7:chmod +x /etc/rc.d/rc.local
四、默许防水墙
centos6:iptables
centos7:firewall
五、文件体式格局封动供职
centos6:/etc/rc.d/rc3.d/ 修正K末端的文件为S
centos7:/usr/lib/systemd/system/高的某就事作一条硬毗连到/etc/systemd/system目次高
六、路由转领
centos6:编纂/etc/sysctl.conf 加添 net.ipv4.ip_forward = 1或者者echo “1” > /proc/sys/net/ipv4/ip_forward
centos7:编纂/etc/sysctl.conf 加添 net.ipv4.ip_forward = 1或者者echo “1” > /proc/sys/net/ipv4/ip_forward
编撰/usr/lib/sysctl.d/50-default.conf 加添 net.ipv4.ip_forward = 1
七、言语装置
centos6:vim /etc/sysconfig/i18n 修正 LANG="zh_CN.UTF-8"
centos7:localectl set-locale.UTF-8
八、工夫异步
CentOS6
$ ntp
$ ntpq -p
CentOS7
$ chrony
$ chronyc sources
九、修正功夫
CentOS6
$ vim /etc/sysconfig/clock
ZONE="Asia/Tokyo"
UTC=fales
$ sudo ln -s /usr/share/zoneinfo/Asia/Tokyo /etc/localtime
CentOS7
$ timedatectl set-timezone Asia/Tokyo
$ timedatectl status
