same problem with "disabled in config", but only in CentOS 6.6/6.7, CentOS 7 not affected- my workaround for CentOS 6:
echo 'NGINX_ULIMIT="-n 6144"' >> /etc/sysconfig/nginx && /usr/local/psa/admin/sbin/httpdmng --reconfigure-all && /usr/local/psa/admin/bin/nginxmng --enable
I have a new problem, not all servers will be updated to nginx 1.9, here a sample:
[root@www nginx]# yum list installed | grep ngin
sw-engine.x86_64 2.13.12-centos6.201502091549 @PSA_12_0_18-dist
sw-nginx.x86_64 1.6.0-1.14051516.centos6 @NGINX_1_6_0-dist
[root@www ~]# cat /usr/local/psa/version
12.0.18 CentOS 6 1200150817.13
[root@www ~]# cat /root/.autoinstaller/microupdates.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<patches>
<product id="plesk" version="12.0.18" installed-at="20150420T091830">
<patch version="63" timestamp="" installed-at="20150904T175725" />
</product>
</patches>
[root@www ~]# /usr/local/psa/admin/sbin/autoinstaller --select-release-current --upgrade-installed-components
You already have the latest version of product(s) and all selected components
installed. Installation will not continue.
Doing restart of Parallels Installer...
