[mapserver-users] mapcache fastcgi

[Rahkonen Jukka (MML)]

Hi,

Could you explain your plan with some more details? What I have understood is that you have experienced that SQLite cache is slower than disk cache in your environment.

What I do not understand is what you are going to reach by running Mapcache as fastcgi instead of running it as Apache module which should be the faster option, and if this has some connection with the SQLite cache vs. disk cache comparison. Do you guess that fastcgi woud make SQLite cache faster?

Aihe: [mapserver-users] mapcache fastcgi

Hi all,

In the end I tried MapCache with sqlite3 cache but it's very slow compared with the disk cache, so I want to setup MapCache with fastCGI on CentOS 7.

I don't understand what I need to install as the fastCGI link in the documentation is broken and I don't know if is up to date.

I already have apache fgcid installed from default in the httpd folder and I use PHP in fastCGI in all the domains, so I'm sure that fastCGI it works, though, I still need the fastCGI library? How can I install it in CentOS 7?

In my apache conf I've already added the lines to load the mapcache module and the mapcache.xml file

LoadModule mapcache_module    modules/mod_mapcache.so

<IfModule mapcache_module>
   <Directory /path/to/directory>
      Require all granted
   </Directory>
   MapCacheAlias /mapcache "/path/to/directory/mapcache.xml"
</IfModule>


I need to leave the previous configuration and add these new lines in the conf files?

FcgidInitialEnv "MAPCACHE_CONFIG_FILE" "/path/to/mapcache/mapcache.xml

<IfModule mod_fcgid.c>
   IPCCommTimeout 120
   MaxProcessCount 10
   FcgidInitialEnv "MAPCACHE_CONFIG_FILE" "/path/to/mapcache/mapcache.xml"
   <Location /map.fcgi>
      Order Allow,Deny
      Allow from all
      SetHandler fcgid-script
   </Location>
  ScriptAlias /map.fcgi "/path/to/mapcache/src/mapcache"
</IfModule>


And then instead of http://myserver/mapcache I need to use http://myserver/fcgi-bin to access mapcache fcgi?
