Solve the Problem of starting the Python module after Ganglia is added

Recently added the Python module of Ganglia, and found that the gmond. init file provided by the Ganglia official source code package is unavailable.

Python is compiled by yourself. If Python is installed in the system rpm package, this problem will not occur.

For example, if the gmond service is started, a message indicating success is displayed. But there is no gmond process in ps. So we studied the gmond. init file.

There is no problem with service gmond stop, and there is no problem with manual gmond command execution. The key is the start parameter, so the code to solve the problem is mainly the following lines:

#! /Bin/sh
#
# Chkconfig: 2345 70 40
# Description: gmond startup script
#
GMOND =/usr/sbin/gmond
# TMPDIR set to SysV IPC ramdrive to avoid include processing failures
TMPDIR =/dev/shm
Export TMPDIR
./Etc/rc. d/init. d/functions
RETVAL = 0
Case "$1" in
Start)
Echo-n "Starting GANGLIA gmond :"
[-F $ GMOND] | exit 1
Daemon $ GMOND
RETVAL =$?
Echo
[$ RETVAL-eq 0] & touch/var/lock/subsys/gmond
;

Because Python is compiled by myself, I think the problem is probably caused by environment variables. Then two lines of code are added, and the following code is added:

1. #! /Bin/sh
2. #
3. # Chkconfig: 2345 70 40
4. # Description: gmond startup script
5. #
6. GMOND =/usr/sbin/gmond
8. # TMPDIR set to SysV IPC ramdrive to avoid include processing failures
9. TMPDIR =/dev/shm
10. Export TMPDIR
12. TPATH = $ PATH
13. ./Etc/rc. d/init. d/functions
14. PATH = $ TPATH
16. RETVAL = 0
18. Case "$1" in
19. Start)
20. Echo-n "Starting GANGLIA gmond :"
21. [-F $ GMOND] | exit 1
23. Daemon $ GMOND
24. RETVAL =$?
25. Echo
26. [$ RETVAL-eq 0] & touch/var/lock/subsys/gmond
27. ;

After the code is changed, there is no problem in using/etc/init. d/gmond for execution, so it must be a problem with the PATH of the environment variable. As mentioned above, my python is compiled by myself. In order not to affect yum, I connect to/usr/local/bin/python, the PATH variable defined by the service gmond start command is defined by the service script instead of defined by the current shell user. Therefore, if I modify the code as follows, it will be okay:

1. #! /Bin/sh
   
2. #
3. # Chkconfig: 2345 70 40
4. # Description: gmond startup script
5. #
6. GMOND =/usr/sbin/gmond
8. # TMPDIR set to SysV IPC ramdrive to avoid include processing failures
9. TMPDIR =/dev/shm
10. Export TMPDIR
12. ./Etc/rc. d/init. d/functions
13. PATH =/usr/local/bin: $ PATH
15. RETVAL = 0
17. Case "$1" in
18. Start)
19. Echo-n "Starting GANGLIA gmond :"
20. [-F $ GMOND] | exit 1
22. Daemon $ GMOND
23. RETVAL =$?
24. Echo
25. [$ RETVAL-eq 0] & touch/var/lock/subsys/gmond
26. ;
