Configure GNUSocial to use its own log file

#logs$config['site']['logdebug'] = false;
$config['site']['logfile'] = '/var/log/statusnet/statusnet.log';

chown -R root:www-data /var/log/statusnet
chmod g+w /var/log/statusnet/statusnet.log

Limit the growth

/var/log/statusnet/*.log
{
        rotate 7
        daily
        missingok
        notifempty
        delaycompress
        compress
        create 660 root www-data
}

    
• /var/log/statusnet/*.log : consider every file named *.log in /var/log/statusnet directory
• rotate 7,  daily,  missingok,  notifempty,  delaycompress,  compress : every day create a new log file and keep the seven latest log files. If nothing was written in the log file than do noting. You can also ignore the log rotation if there is no file at all. And, by the way, compress it so that it takes even less room.
    
• create 660 root www-data : every new log file should be created so that users belonging to www-data group and root itself can read and write the file

Strange behaviour

• /var/log/sysout still contains GNUSocial logs but much less than before. I can read daemon messages and every messages stating that a PHP call is "Including config file: /var/www/statusnet/config.php"
• LOG_DEBUG messages are in /var/log/statusnet/statusnet.log

addPlugin('LogFilter', array( 'priority' => array(LOG_ERR => true,    LOG_INFO => true,    LOG_DEBUG => false),    'regex' => array('/About to push/i' => false,      '/Including config file/i' => false,      '/Successfully handled item/i' => false)      ));

# find . -name "*.php" -exec grep -H "Including config file" '{}' \;./config.php:      '/Including config file/i' => false,./lib/statusnet.php:    common_log(LOG_INFO, "Including config file: " . $_config_file);

common_log(LOG_INFO, "Including config file: " . $_config_file);

//common_log(LOG_INFO, "Including config file: " . $_config_file);

• email
• GNUSocial instance
• XMPP server
• This blog !!

I had to migrate all these services from my previously OVH hosted site. I won't bother you much with the details but it took me 2 days and a half to migrate it all.

I started with my email server because I like to start with difficult things. And then my GNUSocial instance. The XMPP Server was a piece of cake (If you retrieve what was parameterized in /var/lib/prosody too ...).

As for now it runs smoothly and very very silently.

The largest memory hog is mysql of course !

IP address bans by day China comes first with 97 bans. It is followed by the United states of america (50 bans) and then Germany (30 bans).
