How to check if a WildFly Server has started successfully using command/script? - wildfly

Question

I want to write a script to manage the WildFly start and deploy, but I'm having trouble now. To check if the server has started, I found the command
./jboss-cli.sh -c command=':read-attribute(name=server-state)' | grep running
But when the server is starting, because the controller is not available, ./jboss-cli.sh -c fails to connect and returns an error.
Is there a better way to check whether WildFly started completely?

Answer 1

I found a better solution. The command is
netstat -an | grep 9990 | grep LISTEN
Check the management port (9990) state before the WildFly is ready to accept management commands.
After that, use ./jboss-cli.sh -c command=':read-attribute(name=server-state)' | grep running to check if the server has started. Change the port
if the management port config is not the default 9990.
Here is my start & deploy script, the idea is continually check until the server started.
Then, use the jboss-cli command to deploy my application. And just print the log to the screen, so don't need to use another shell to tail the log file.
#!bin/sh
totalRow=0
printLog(){ #output the new log in the server.log to screen
local newTotal=$(awk 'END{print NR}' ./standalone/log/server.log) #quicker than wc -l
local diff=$(($newTotal-$totalRow))
tail -n $diff ./standalone/log/server.log
totalRow=$newTotal
}
nohup bin/standalone.sh>/dev/null 2>&1 &
echo '======================================== Jboss-eap-7.1 is starting now ========================================'
while true #check if the port is ready
do
sleep 1
if netstat -an | grep 9990 | grep LISTEN
then
printLog
break
fi
printLog
done
while true #check if the server start success
do
if bin/jboss-cli.sh --connect command=':read-attribute(name=server-state)' | grep running
then
printLog
break
fi
printLog
sleep 1
done
echo '======================================== Jboss-eap-7.1 has started!!!!!! ========================================'
bin/jboss-cli.sh --connect command='deploy /bcms/jboss-eap-7.1/war/myApp.war' &
tail -f -n0 ./standalone/log/server.log
