Updating to wpredis failed

#1

My site is currently using --wpfc and I want to try --wpredis so I tried updating my cache by using this command:

ee site update www.example.com --wpredis

Type "y" to continue [n]: y
Adding repository for Redis, please wait...
Updating apt-cache, please wait...

NGINX configuration check failed.
root@server:~# nginx -t
nginx: [emerg] unknown "srcache_fetch_status" variable
nginx: configuration file /etc/nginx/nginx.conf test failed
Redis update gave nginx error

Here’s the error source.

/etc/nginx/conf.d/redis.conf


# Log format Settings
log_format rt_cache_redis '$remote_addr $upstream_response_time $srcache_fetch_status [$time_local] '
'$http_host "$request" $status $body_bytes_sent '
'"$http_referer" "$http_user_agent"';

I’m getting the same error message.

Hello wibblet,

Here’s the solution I have done. Remove your current cache first by using this command.

ee site update example.com --wp

Then run this command:

ee site update example.com --wpredis

It will work. :slight_smile:

@seyntjim @wibblet

dpkg -l | grep nginx

I have already fixed mine, but here you go:

root@server:/var/log/nginx# dpkg -l | grep nginx
ii  nginx-common                    1.8.0-8ppa                            small, powerful, scalable web/proxy server - common files
ii  nginx-custom                    1.8.0-8ppa                            nginx web/proxy server with custom setup

Glad to know your problem fixed :slight_smile:

that was just to confirm you have updated nginx package, which has necessary module for redis cache.

@wibblet

@wibblet

thats it !! you need to upgrade your server packages to fix above problem occurred to you.

As your server having nginx package that has no necessary modules for cacheing with redis.

apt-get update && apt-get upgrade

above command will upgrade your nginx package to latest package.
