LinuxOpensuse command to view process information
There are a lot of commands to view the process, and I just listed a few of the ones I used most.
Netstat-tln / / View service listening port
Netstat / / View the process number
Ps-aux / / View the process number
Ps-aux | more / / View all
Ps-ef | grep mysql / / View the process of mysql
Kill-9 3306 / / forcibly kill process number 3306
Opensuse Command Firewall Settings
Set up the firewall: yast (setup)
View firewall settings: iptables-L
Turn off the firewall: iptables-F
Red Hat linux as 4 modified / etc/sysconfig/iptables
Add-A RH-Firewall-1-INPUT-m state-- state NEW-m tcp-p tcp-- dport 80-j ACCEPT
Indicates that access to port 80 is allowed
For the configuration to take effect, you can restart the computer, or allow the following two commands:
# service iptables stop
# service iptables start
