Monit not invoking start or stop actions; even though after passing PATH variable to the script.

[Venkata M]

Following is the script i am using to restart the apache instance; monit is running as root user

But i am able to execute same script from terminal. Monit version 5.30.0

There is a shebang line in the “apachectl“ script as “#!/bin/sh“

check process bamboo-nosm matching /local/mnt/apache/bamboo-nosm
start program="/bin/sh -c 'PATH=/bin:/usr/bin:/root/bin /local/mnt/apache/bamboo-nosm/bin/apachectl start >> /temp/file2'"
stop program="/bin/sh -c 'PATH=/bin:/usr/bin:/root/bin /local/mnt/apache/bamboo-nosm/bin/apachectl stop >> /temp/file2'"
if does not exist then restart

‌

when i executed following command “monit -vv reload” got verbose as follows; even though scripts exists in the path; like program doesn’t exist.
/etc/monit/apacheinstancescontrolfile.conf:3: Program does not exist: 'program='
/etc/monit/apacheinstancescontrolfile.conf:4: Program does not exist: 'program='

‌

for testing i stopped the apache instance but monit is not invoking actions;

in the log i am getting as follows

If I see this correctly, it's a syntax-error in your config. But to be honest, I think, it's more a syntax error in the monit syntax parser.

As the error states, it tries to run a program calles programm=...

The root error might be here: https://bitbucket.org/tildeslash/monit/src/e985b8ec67d2ee0d724d86a75517d2387a435fb6/src/l.l#lines-138

startarg       start{ws}?(program)?{ws}?([=]{ws})?["]
                                          ^ IF there IS an equal-sign (=) there MUST be a space after it.

You might want to try

start program = "/bin/sh -c 'PATH=/bin:/usr/bin:/root/bin /local/mnt/apache/bamboo-nosm/bin/apachectl start >> /temp/file2'"
stop program = "/bin/sh -c 'PATH=/bin:/usr/bin:/root/bin /local/mnt/apache/bamboo-nosm/bin/apachectl stop >> /temp/file2'"

I confirm Henning’s s analysis, will fix. The workaround with adding spaces around the '=' character works fine

[Tildeslash]

Fixed: Issue #1035: If the start/stop/restart program statement contains the equal sign, which is not followed by a space character, the configuration is not parsed correctly.
