Try to switch to apache and then back to apache.

Try to switch to apache and then back to apache.

You mean, switch to apache and then back to nginx?

[gorgon]

When I switched to apache to test if php worked there but


Switched back to nginx, still getting 502 Bad Gateway.

Did all of them, rebooted server, still stuck at bad gateway

confirmed:
PHP-FM is not being installed after switching to nginx.

I solved it manually by

Installing php-fm
changing ports from 57xxx to 9000

[gorgon]

To be honest, this build of kloxo has no support for nginx.

1. Php-fm broken.

2. /home/nginx/conf/globals/php-fpm.conf:
    location / - already defined, disabling users create location / rules in website.conf
Errors: nginx: [emerg] duplicate location "/" in /home/nginx/conf/globals/php-fpm.conf:54

3. Multiple PHP-modules missing, such as
php-pecl-apc php-mysql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml

After fixing all the problems, I am not able to access site with nginx.

Switch from and to nginx running on my server but with 'extra' actions:

Steps:
1. Switch to nginx on 'switch applications'
2. run 'sh /script/fixweb'
3. run 'sh /script/restart-services'
4. If found error on step 3 (like 'Address already in use'), need reboot

About php branch switch. Php branch switch only switch for php and build-in module. External module like gd need reinstall separately. Kloxo-MR use 'yum replace' for switch php.

I've re-installed 1815 build for the 4th time now, just after re-install I go switch applications from apache -> nginx, nginx -> apache and then again apache -> nginx, fixweb/phpfpm/php and reboot the whole server. I get 502 Gateway error.
I am pretty sure the php-fpm socks is not connected. When I manually install php-fpm and changed port to 9000 and then nginx worked.

Have you try other php-types (like fcgid) for to make php-fpm or other is wrong?.

How do you switch php types when in nginx?(php type option disabled for nginx) Would like to bring you one more issue, on apache(fresh install), php type: ruid2, getting blank php pages.

Sorry, I think you use nginx-proxy instead nginx.

Ok, we can discuss via YM or GTalk.

Issue Resolved.

Firstly downgrade nginx (1.4.1)

1. already set 1 domain
2. set to apache, php 5.3 and php-fpm_event
3. test domain for running well
4. if something wrong, run fixweb and restart-services
5. if setting for running well and then ready switch to nginx

Thank you MR
