Featured CentOS 7.x How to help test .08 CentOS 7 Betas with Github code ?

You're welcome and feedback appreciated

Thanks mate..StartledPhoenix's suggestion was just what Centmin Mod needed as a temp work around until full jailed/chroot user features are ready

---

 

On fresh Centmin Mod .08 installs centmin.sh has a new option PUREFTPD_DISABLED=n change that to PUREFTPD_DISABLED=y to disable pure-ftpd service post initial install. It's still installed but disabled after install and nginx add vhost menu option 2 in centmin.sh automatically detects PUREFTPD_DISABLED=y and doesn't prompt or do any pure-ftpd virtual ftp user routines and skips those for old method prior to pure-ftpd

also dedicated thread at Centmin Mod .08 beta + pure-ftpd virtual FTP user support | Centmin Mod Community

 

Updated .08 beta with a few commits including OpenSSL 1.0.2 for Nginx static compile

OpenSSL 1.0.2 testing and feedback thread here CentOS updating for OpenSSL 1.0.2 testing feedback please | Centmin Mod Community

 

committed a fix to Centmin Mod .08 beta builds to remove .i686 packages if 64bit OS is detected Commits · centminmod/centminmod · GitHub

 

some folks reported centos 7 + openvz + centmin mod nginx would have issues with nginx restarts failing to start up

i did test it and did have such problems at time of reports, but lately haven't experienced it so not sure yet - something I'd need to look at when I have more free time

 

yeah it's weird, most recent tests for me have it working on CentOS 7 + OpenVZ + .08 beta but was failing before.

 

thanks to @jeffwidman for giving me access to his CentOS 7 + OpenVZ server to troubleshooting Centmin Mod .08's nginx failure to restart issue. I found the problem and why it only is a problem on some OpenVZ + CentOS 7 installs. It seems some OpenVZ images that web hosts use have Apache http server installed an running out of the box, so when Nginx tries to restart/start it can not bind to port 80 and thus fails to start Nginx. OpenVZ images I test with do not have Apache http server running so I didn't experience this.

For CentOS 6 and Centmin Mod .08 betas, Apache is stopped and disabled but for some reason CentOS 7 installs lets Apache still run. So will need to fix that.

The proof

nginx error on restart/start

Code:

ngxrestart
Restarting nginx (via systemctl):  Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
                                                           [FAILED]

journalctl -xn

find what is listening on port 80

Code:

lsof -i :80
COMMAND   PID   USER   FD   TYPE     DEVICE SIZE/OFF NODE NAME
httpd     399   root    4u  IPv6 1974102768      0t0  TCP *:http (LISTEN)
httpd     424 apache    4u  IPv6 1974102768      0t0  TCP *:http (LISTEN)
httpd   30703 apache    4u  IPv6 1974102768      0t0  TCP *:http (LISTEN)

Code:

systemctl stop httpd.service 

Code:

ngxrestart
Restarting nginx (via systemctl):                          [  OK  ]

so to figure out why Centmin Mod .08 is allow httpd service to run still after initial install

edit: was missing a routine specific for CentOS 7 detection of Apache heh, committed fix to .08 beta on github update inc/nginx_install.inc for CentOS 7 + OpenVZ ensure Apache is disa... · f511c35 · centminmod/centminmod · GitHub

edit2: much closer to making .08 a stable release - just need more testing feedback for CentOS 7 + .08 beta

 

Made minor update to .08 beta's memcached init.d file as it was missing a few variables that I recently added update /etc/init.d/memcached fix missing parameters for .08 beta · cf55281 · centminmod/centminmod · GitHub

For existing Centmin Mod users you can simply just grab and update your /etc/init.d/memcached file using these commands and then readjust the memory limit you allocated to memcached server(s) if you customised the memory allocation

Code:

rm -rf /etc/init.d/memcached; wget -O /etc/init.d/memcached https://raw.githubusercontent.com/centminmod/centminmod/123.08centos7beta01/config/memcached/memcached; chmod +x /etc/init.d/memcached
service memcached restart

 

Yeah ZOPCACHEDFT overrides default APC Cache apc.ini

 

updated .08 beta 's MariaDB 10 my.cnf default template with correct innodb buffer pool dump and load settings update default MariaDB 10 my.cnf template settings for .08 beta · 1eaecdb · centminmod/centminmod · GitHub

Thanks @jeffwidman MariaDB - Curious why InnoDB Buffer Pool load on startup isn't enabled? | Centmin Mod Community

 

Updated .08 beta to re-enable disable_function for PHP and shell_exec for starters re-enable PHP shell_exec restrictions in disable_functions for php.conf ... · b348d37 · centminmod/centminmod · GitHub

 

no no.. shell_exec is for PHP code trying to run shell commands.. so reverse of what you want.. You can still run php scripts via SSH command line.

 

Made a few .08 beta commits (March 3, 2015) for OpenVZ + CentOS 7 issues and work arounds for what @jeffwidman reported issue of CentOS 7 + OpenVZ installs on system reboot loose ssh access etc Commits · centminmod/centminmod · GitHub
