Monitoring process status and automatic restart process under Unix/linux __linux

Tools: Daemontools

Daemontools is a set of UNIX service Administration tools developed by QMail's author DJB, where a program named supervise can be used for service startup, stop service restart, and so on.

Installation:
Create A/package Directory:

Mkdir-p/package
chmod 1755/package
Cd/package

Download http://cr.yp.to/daemontools/daemontools-0.76.tar.gz Into/package. Unpack the Daemontools package:

Gunzip Daemontools-0.76.tar
TAR-XPF Daemontools-0.76.tar
Rm-f Daemontools-0.76.tar
CD admin/daemontools-0.76

Compile and set up the Daemontools programs:

Package/install

Test whether the installation was successful:

# Ps-ef | grep Svscan

# Mans Svscan

Use the supervise program for program management monitoring, take memcache as an example, Memcache directory is in/usr/local/memcache

Create a new corner in the Memcache directory this file

#vim Run

The contents are as follows

#!/bin/sh

EXEC 2>&1

Exec/usr/local/memcache/bin-u root-d

Run:

Supervise/usr/local/memcache

Verify that the monitoring memcache is successful:

kill-9 [memcached PID]---kill the process
Ps-aux|grep memcached----View process

To view the process, if there is a memcached process "just different than the previous PID", the automatic reboot is successful.
