In this blog i will explain how to configure the access, error and slow logs of php-fpm and to modify the format in which the logs are received.<\/p>\n
Prerequisites:<\/p>\n
Lets have an application that uses the php5-fpm module, in this case, we will use the WordPress Application running on a LEMP stack.<\/p>\n
To enable the logs , two files are relevant, namely Firstly, open the first file for editing<\/p>\n [js]vi \/etc\/php5\/fpm\/php-fpm.conf[\/js]<\/p>\n Set the desired location for getting error logs. The line should look like: Next open the second file for editing<\/p>\n [js] vi \/etc\/php5\/fpm\/pool.d\/www.conf [\/js]<\/p>\n Look for the line containing the location of access.log and set it to the desired path. Understanding the access log format:<\/p>\n access.format = %R – %u %t \\”%m %r%Q%q\\” %s %f %{mili}d %{kilo}M %C%%”<\/strong><\/p>\n %R : remote IP address %t : server time of receiving request Example:<\/p>\n [js] The format of the access log can be altered as per desire.<\/p>\n The path for slow log is defined is defined just beneath the block of access logs. Uncomment the line and set the desired path for getting slow logs. Ex: request_slowlog_timeout = 10<\/strong><\/p>\n At the bottom of the file set Create the directory(if it does not exist) where the logs are to be created.<\/p>\n [js]mkdir -p \/var\/log\/php5[\/js]<\/p>\n Restart the php5-fpm service<\/p>\n [js]service php5-fpm restart[\/js]<\/p>\n Henceforth you will start getting the logs at the set path.<\/p>\n","protected":false},"excerpt":{"rendered":" In this blog i will explain how to configure the access, error and slow logs of php-fpm and to modify the format in which the logs are received.
