| + | ====== Script to start/stop jobs ====== | ||
| + | Startup scripts samples. | ||
| + | |||
| + | ===== Start ===== | ||
| + | THIS DOES NOT QUITE WORK! The job starts but the pid is not the real pid! So the stop is also bad because of this. | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | RUN_FILE=/var/run/somejob.pid | ||
| + | nohup some-job > /dev/null 2>&1 & | ||
| + | echo $! >> $RUN_FILE | ||
| + | exit | ||
| + | </code> | ||
| + | |||
| + | ===== Stop ===== | ||
| + | THIS DOES NOT QUITE WORK! | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | RUN_FILE=/var/run/somejob.pid | ||
| + | for pids in `cat $RUN_FILE`; | ||
| + | do | ||
| + | echo "Killing: $pids" | ||
| + | kill -9 $pids | ||
| + | done | ||
| + | </code> | ||
| + | |||
| + | ===== Restart ===== | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | /path/to/stop-job.bash | ||
| + | #sleep 5 | ||
| + | /path/to/start-job.bash | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ====== Other scripts ====== | ||
| + | ===== Simple start ===== | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | HAPCOUNT=`pgrep haproxy|wc -l` | ||
| + | if [ $HAPCOUNT -eq 0 ] | ||
| + | then | ||
| + | echo "Starting haproxy ..." | ||
| + | haproxy -f /etc/haproxy/haproxy.cfg | ||
| + | else | ||
| + | echo "haproxy already running" | ||
| + | fi | ||

| + | ===== Simple stop ===== | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | HAPCOUNT=`pgrep haproxy|wc -l` | ||
| + | if [ $HAPCOUNT -eq 0 ] | ||
| + | then | ||
| + | echo "haproxy not running" | ||
| + | exit | ||
| + | fi | ||
| + | # | ||
| + | for pids in `pgrep haproxy`; | ||
| + | do | ||
