最近在本地虚拟机搭建环境,使用service 命名报 service:command not found ;于是百度了好多都没解决,最后在官网看了下得知。
CentOS 7.0中已经没有service命令,而是启用了systemctl服务器命令
systemctl 是系统服务管理器命令,它实际上将 service 和 chkconfig 这两个命令组合到一起。
任务 |
旧指令 |
新指令 |
使某服务自动启动 |
chkconfig –level 3 httpd on |
systemctl enable httpd.service |
使某服务不自动启动 |
chkconfig –level 3 httpd off |
systemctl disable httpd.service |
检查服务状态 |
service httpd status |
systemctl status httpd.service (服务详细信息) systemctl is-active httpd.service (仅显示是否 Active) |
显示所有已启动的服务 |
chkconfig –list |
systemctl list-units –type=service |
启动某服务 |
service httpd start |
systemctl start httpd.service |
停止某服务 |
service httpd stop |
systemctl stop httpd.service |
重启某服务 |
service httpd restart |
systemctl restart httpd.service |
下面以nfs服务为例:文章来源地址https://www.yii666.com/article/24315.html
1.启动nfs服务
systemctl start nfs-server.service
2.设置开机自启动
systemctl enable nfs-server.service
3.停止开机自启动
systemctl disable nfs-server.service
4.查看服务当前状态
systemctl status nfs-server.service
5.重新启动某服务
systemctl restart nfs-server.service
6.查看所有已启动的服务
systemctl list -units --type=service
开启防火墙22端口
iptables -I INPUT -p tcp --dport 22 -j ACCEPT
关闭SElinux:
修改/etc/selinux/config文件中的SELINUX=”” 为 disabled,然后重启
彻底关闭防火墙:
sudo systemctl status firewalld.service
sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service
