install IBM MQ 9.1 on Ubuntu

1. download IBM_MQ_9.1.5_UBUNTU_X86-64.tar.gz from IBM site and unzip it to /tmp
2. create mqm user and group on Ubuntu:
   root@ubunu2004:/usr/lib# useradd mqm -m -s /bin/bash
   root@ubunu2004:/usr/lib# id mqm
   uid=1001(mqm) gid=1001(mqm) groups=1001(mqm)
3. create filesystem/dir for MQ
   mkdir /var/mqm
   mkdir -p /var/mqm/errors
   mkdir -p /var/mqm/trace
   mkdir -p /var/mqm/qmgrs
   mkdir -p /var/mqm/log
   chown -R mqm:mqm /var/mqm
4. make sure Linux already installed libgcc_s.so and libstdc++.so.6
5. update threads-max and nofile setting for system and users
   echo 32768 > /proc/sys/kernel/threads-max
   ulimit -n 10240
   or add below lines into /etc/security/limits.conf for nofile limit:

   * soft     nproc          65535
   * hard     nproc          65535
   * soft     nofile         65535
   * hard     nofile         65535
   root soft     nproc          65535
   root hard     nproc          65535
   root soft     nofile         65535
   root hard     nofile         65535

6. start installation with root:
   cd /tmp/MQServer/
   ./mqlicense.sh -text_only
   apt install ./ibmmq-runtime_9.1.5.0_amd64.deb
   apt install ./ibmmq-gskit_9.1.5.0_amd64.deb
   apt install ./ibmmq-server_9.1.5.0_amd64.deb
   apt install ./ibmmq-jre_9.1.5.0_amd64.deb
   apt install ./ibmmq-java_9.1.5.0_amd64.deb
   apt install ./ibmmq-explorer_9.1.5.0_amd64.deb
   apt install ./ibmmq-samples_9.1.5.0_amd64.deb
   …..
   you can install other packages if you want, but we need at least runtime, gskit and server for a MQ env.
7. create and start qmgr with mqm ID
   su – mqm
   cd /opt/mqm/bin
   ./crtmqm -q -d MY.DEFAULT.XMIT.QUEUE -u SYSTEM.DEAD.LETTER.QUEUE SATURN.QUEUE.MANAGER
   ./strmqm SATURN.QUEUE.MANAGER
   ./endmqm SATURN.QUEUE.MANAGER
   ./dspmq -m SATURN.QUEUE.MANAGER
   mqm@ubunu2004:/opt/mqm/bin$ ./dspmq -m SATURN.QUEUE.MANAGER
   QMNAME(SATURN.QUEUE.MANAGER) STATUS(Running)
   mqm@ubunu2004:/opt/mqm/bin$ ./dltmqm qmgr1
   IBM MQ queue manager ‘qmgr1’ deleted.
8. verify the installation with command
   you can setup your default mqm env first:
   mqm@ubunu2004:/opt/mqm/bin$ source /opt/mqm/bin/setmqenv -s
   then create a new qmgr and putmsg/getmsg:
   crtmqm QMA
   strmqm QMA
   mqm@ubunu2004:~$ runmqsc QMA
