<div dir="ltr"><div>Hi,<br><br>So it seems that my setup was not working because SELinux was not disabled. Once I disabled it, my web server displays the correct index.html. In my master node's /var/www/html, I see the correct index.html, but in the slave's /var/www/html I still see the old index.html. Once I do a failover and the slave becomes the master, I see the correct index.html in the new master's /var/www/html, and the website works as expected with no downtime.<br><br>Is this the correct behavior? I was under the impression that both nodes will reflect the same contents, and whatever is changed on the master will be replicated in near real time in the slave.<br><br></div>Also, I wish now with to put a mySQL database in the DRBD block device. What would the procedure be to do so? I suppose it would be similar to the Apache example, except /var/www/html would be replaced by wherever the DB is installed?<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Nov 13, 2014 at 9:42 AM, Sihan Goi <span dir="ltr"><<a href="mailto:goister@gmail.com" target="_blank">goister@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hi,<br><br></div>getenforce returns "Enforcing"<br></div>ls -dZ /var/www/html returns "drwxr-xr-x. root root system_u:object_r:httpd_sys_content_t:s0 /var/www/html" on both nodes.<br><br></div>Running restorecon doesn't change the ls-dZ output.<br></div><div class="gmail_extra"><div><div class="h5"><br><div class="gmail_quote">On Wed, Nov 12, 2014 at 2:24 PM, Vladislav Bogdanov <span dir="ltr"><<a href="mailto:bubble@hoster-ok.com" target="_blank">bubble@hoster-ok.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span>11.11.2014 07:27, Sihan Goi wrote:<br>

</span>It look like apache is unable to stat its document root.<br>
Could you please show output of two commands:<br>
<br>
getenforce<br>
ls -dZ /var/www/html<br>
<br>
on both nodes when fs is mounted on one of them?<br>
If you see 'Enforcing', and the last part of the selinux context of a<br>
mounted fs root is not httpd_sys_content_t, then run<br>
'restorecon -R /var/www/html' on that node.<br>
