一、ps -aux 查找到对应进程pid号
[root@www ~]# ps -aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND mysql 9844 10.2 8.7 2215852 704072 ? Sl 13:30 24:42 /www/server/mys www 13454 2.5 0.4 287960 32276 ?

二、cd /proc/PID号
[root@www ~]# cd /proc/9844 [root@www 9844]# ll total 0 dr-xr-xr-x 2 mysql mysql 0 Oct 2 17:34 attr -rw-r--r-- 1 root root 0 Oct 2 17:34 autogroup -r-------- 1 root root 0 Oct 2 17:34 auxv -r--r--r-- 1 root root 0 Oct 2 17:34 cgroup --w------- 1 root root 0 Oct 2 17:34 clear_refs -r--r--r-- 1 root root 0 Oct 2 13:33 cmdline -rw-r--r-- 1 root root 0 Oct 2 13:33 comm -rw-r--r-- 1 root root 0 Oct 2 17:34 coredump_filter -r--r--r-- 1 root root 0 Oct 2 17:34 cpuset lrwxrwxrwx 1 root root 0 Oct 2 17:34 cwd -> /www/server/data -r-------- 1 root root 0 Oct 2 17:34 environ lrwxrwxrwx 1 root root 0 Oct 2 13:31 exe -> /www/server/mysql/bin/mysqld dr-x------ 2 root root 0 Oct 2 13:33 fd dr-x------ 2 root root 0 Oct 2 17:34 fdinfo -rw-r--r-- 1 root root 0 Oct 2 17:34 gid_map -r-------- 1 root root 0 Oct 2 13:31 io -r--r--r-- 1 root root 0 Oct 2 17:34 limits -rw-r--r-- 1 root root 0 Oct 2 17:34 loginuid dr-x------ 2 root root 0 Oct 2 17:34 map_files -r--r--r-- 1 root root 0 Oct 2 17:34 maps -rw------- 1 root root 0 Oct 2 17:34 mem -r--r--r-- 1 root root 0 Oct 2 17:34 mountinfo -r--r--r-- 1 root root 0 Oct 2 17:34 mounts -r-------- 1 root root 0 Oct 2 17:34 mountstats dr-xr-xr-x 5 mysql mysql 0 Oct 2 17:34 net dr-x--x--x 2 root root 0 Oct 2 17:34 ns -r--r--r-- 1 root root 0 Oct 2 17:34 numa_maps -rw-r--r-- 1 root root 0 Oct 2 17:34 oom_adj -r--r--r-- 1 root root 0 Oct 2 17:34 oom_score -rw-r--r-- 1 root root 0 Oct 2 17:34 oom_score_adj -r--r--r-- 1 root root 0 Oct 2 17:34 pagemap -r-------- 1 root root 0 Oct 2 17:34 patch_state -r--r--r-- 1 root root 0 Oct 2 17:34 personality -rw-r--r-- 1 root root 0 Oct 2 17:34 projid_map lrwxrwxrwx 1 root root 0 Oct 2 17:34 root -> / -rw-r--r-- 1 root root 0 Oct 2 17:34 sched -r--r--r-- 1 root root 0 Oct 2 17:34 schedstat -r--r--r-- 1 root root 0 Oct 2 17:34 sessionid -rw-r--r-- 1 root root 0 Oct 2 17:34 setgroups -r--r--r-- 1 root root 0 Oct 2 17:34 smaps -r--r--r-- 1 root root 0 Oct 2 17:34 stack -r--r--r-- 1 root root 0 Oct 2 13:30 stat -r--r--r-- 1 root root 0 Oct 2 13:30 statm -r--r--r-- 1 root root 0 Oct 2 13:34 status -r--r--r-- 1 root root 0 Oct 2 17:34 syscall dr-xr-xr-x 121 mysql mysql 0 Oct 2 13:39 task -r--r--r-- 1 root root 0 Oct 2 17:34 timers -rw-r--r-- 1 root root 0 Oct 2 17:34 uid_map -r--r--r-- 1 root root 0 Oct 2 17:34 wchan
三、cat status,找到父进程的PPID号
[root@www 9844]# cat status Name: mysqld Umask: 0026 State: S (sleeping) Tgid: 9844 Ngid: 0 Pid: 9844 PPid: 7931 TracerPid: 0 Uid: 1001 1001 1001 1001 Gid: 1001 1001 1001 1001 FDSize: 512 Groups: 1001 VmPeak: 2215856 kB VmSize: 2215852 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 706120 kB VmRSS: 706120 kB RssAnon: 695452 kB RssFile: 10668 kB RssShmem: 0 kB VmData: 2135320 kB VmStk: 132 kB VmExe: 22108 kB VmLib: 9028 kB VmPTE: 1740 kB VmSwap: 0 kB Threads: 119 SigQ: 0/31202 SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000084007 SigIgn: 0000000000003006 SigCgt: 00000001800006e8 CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: 0000001fffffffff CapAmb: 0000000000000000 NoNewPrivs: 0 Seccomp: 0 Speculation_Store_Bypass: vulnerable Cpus_allowed: 3 Cpus_allowed_list: 0-1 Mems_allowed: 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000001 Mems_allowed_list: 0 voluntary_ctxt_switches: 26265 nonvoluntary_ctxt_switches: 96
可以看到示例持PPid: 7931
四、先杀掉父进程：kill -9 PPID号
kill -9 7931
五、再杀掉子进程：kill -9 PID号
kill -9 9844
