1. Check the number of nginx running processes
[root@iZ28j69c9oxZ logs]# ps -ef | grep nginx | wc -l
10
2. Check the number of web server process connections
[root@iZ28j69c9oxZ logs]# netstat -antp | grep 80 | grep ESTABLISHED -c
1
3, View the number of MySQL process connections
[root@iZ28j69c9oxZ logs]# ps -ef | grep mysqld -c
3
The above introduces the Centos65 command to view the number of nginx concurrent connections and TCP connection status, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
