Not able to change hhvm user from hhvm to nginx on CentOS 7 - hhvm

Question

I am able to run HHVM with user hhvm as it is default. But when trying to change the user to nginx I get error when checking it's status.
$ vim /usr/lib/systemd/system/hhvm.service
I add the following
[Unit]
Description=HipHop Virtual Machine (FCGI)
[Service]
ExecStart=/usr/local/bin/hhvm -c /etc/hhvm/server.ini -c /etc/hhvm/php.ini --user nginx --mode daemon
[Install]
WantedBy=multi-user.target
on the config file
$ vim /etc/hhvm/server.ini
this is what I have for config
pid = /var/run/hhvm/pid
hhvm.server.ip = 127.0.0.1
hhvm.server.port = 9000
;hhvm.server.file_socket = /var/run/hhvm/hhvm.sock
hhvm.server.user = nginx
hhvm.server.type = fastcgi
hhvm.server.default_document = index.php
hhvm.source_root = /srv/www/public_html
hhvm.server.always_use_relative_path = false
hhvm.server.thread_count = 32
hhvm.resource_limit.max_socket = 65536
hhvm.jit = true
hhvm.jit_a_size = 67108864
hhvm.jit_a_stubs_size = 22554432
hhvm.jit_global_data_size = 22554432
hhvm.jit_profile_interp_requests = 3
; mysql
hhvm.mysql.socket = /var/lib/mysql/mysql.sock
hhvm.mysql.typed_results = true
; logging
hhvm.log.use_syslog = false
hhvm.log.use_log_file = true
hhvm.log.file = /var/log/hhvm/error.log
hhvm.log.level = Warning
hhvm.log.always_log_unhandled_exceptions = true
hhvm.log.runtime_error_reporting_level = 8191
after this I run the commands
$ systemctl daemon-reload
$ systemctl start hhvm.service
$ systemctl status hhvm.service
When I check for status I get the following message
hhvm.service - HipHop Virtual Machine (FCGI)
Loaded: loaded (/usr/lib/systemd/system/hhvm.service; enabled)

Apr 10 23:43:00 centos7.local systemd[1]: Unit hhvm.service entered failed state.
Also I have to create this folder manually every time I reboot
$ mkdir /var/run/hhvm
Why does it get deleted automatically?

Answer 1

Can you start it in daemon mode normally?
Just execute command you see in the service file, the ExecStart one.
And for the missing hhvm folder maybe you could write a command to make the dir before starting script using ExecStartPre or you could change the location of the pid file to just /var/run folder.
#limilaw i think you can change the user in the service file but be careful as you can mess things up.
