problem with configuring varnish

[Seyed Ali Roshan]

hi all,
i installed olsws and it works on 8088 (in listeners)
i installed varnish and config these file:
/etc/varnish/default.vcl :
put in backend :
.host = "my_server_ip"
.port = "8088"
-----------------------
/etc/sysconfig/varnish
put
VARNISH_LISTENER_PORT=8088
put now when i open on port 80 i just get error 503
what do i have to do?

it worked, so tnx but i want that my ols works on 8088
what do i have to do?
do you think this problem has conection with firewall for example iptables of csf?

Hi Seyed,

If you mean you want to access 8088 to get to Varnish, then Varnish gets the page from OLS at another port, you just have to set OLS to another port.

Everything that used to be port 80 should be switched to 8088. Everything that was 8088 should be switched to another one, for example 8089.

I hope this helps,
Kevin

no no no
i think i couldn't give you my main idea
i want that varnish is worked on port 80 and ols is worked on 8088
i pass all config but still get 503 error
and every thing goes fine when ols is worked on 8080 and reconfig(same config for port 8088) for port 8080

Hi Seyed,

Does it work if you use host 127.0.0.1 and port 8088? Your post suggested that you used "my_server_ip", I assume that means you used the outward facing IP, rather than localhost/127.0.0.1. As I mentioned in that thread, I was able to get it working with port 8088.

Let me know,
Kevin

my config is now :
backend:
.host = "127.0.0.1"
.port = "8080"
and varnish:
LISTEN_VARNISH_PORT: 80
and it worked
but when put .port = "8088" (and set listener on ols to 8088) it gives me the 503 error

Hi Seyed,

When it is set to 8088, are you able to access the pages directly, rather than through Varnish?

Seyed,

I noticed that you made a few posts regarding caching solutions.

I did not have any issues when trying Varnish cache myself, so I am not sure about what the problem is.

If you are interested, we do have a guide for installing the cache module, which may be enough for your uses.

A quick note if you decide to use our cache module, some more information regarding public/private caches can be found here.

they don't have problem with php 7?

No, our cache module should not be impacted by php 7.

I just did a fresh install and it works.

Varnish version 4.1.1 - binary at /usr/local/sbin/varnishd

sudo /usr/local/sbin/varnishd

Gave me a warning message:
Warning: Neither -b nor -f given, won't start a worker child.
Master process started, use varnishadm to control it.

sudo /usr/local/sbin/varnishd -b 127.0.0.1:8088
/usr/local/lsws/bin/lswsctrl stop
/usr/local/lsws/bin/lswsctrl start
curl -i http://127.0.0.1:8088 // works
curl -i http://127.0.0.1:80     // works

What steps did you take?

Kevin

 

[Seyed Ali Roshan]

the problem is that -> we got no warning or error message on starting or restarting the services
but when accessed to port 80 ( that varnish worked on it) we got 503 Error!!!!!!

Hi Seyed,

Try running the varnish log (for me it is sudo varnishlog).
If it says can't open log, you might not have the right permissions, or there is a problem with varnish, not with OLS.

If there are no warnings/errors, that means the log output is running.

When it is running, access a page at :80. Something should output.

This is my output:

this log for time when every thing work well(varnish work on 80 and ols work on 8080)
i think there is no need for more answer about this matter because every thing works nice on 80 and 8080 and no one else have my problem so it's might because of my server firewall ruls
so thanks for your support
