If you need to change your catalina.out date and time format, you can add this line to your tomcat/conf/logging.properties:
1catalina.java.util.logging.SimpleFormatter.format=[%1$td.%1$tm.%1$tY %1$tH:%1$tM:%1$tS,%1$tL] %4$s [%2$s] %5$s %6$s %n
You may need to convert URI levels to query string parameters, for example if want to be RESTful compliant with PHP.
Try this one:
RewriteEngine on RewriteRule ^/(\w+)/(\w+)$ /path_of_index.php?lev1=$1&lev2=$2 [QSA,L]
In this case the first URI level will be converted to a query string parameter called lev1, while the second will be converted to a query string parameter called lev2, each one with the respective values.
For example, the uri /user/list will be passed to index.php and will become index.php?lev1=user&lev2=list
An eventual query string will be passed, eventually overriding lev1 and lev2 parameters.
Docker is becoming the “today standard” of lxs linux containers.
I think I will avoid learning Kubernetes to handle dockerized hosts, and I will study Docker Engine, Docker Swarm and Docker Machine and its REST APIs instead.
I started from here: https://docs.docker.com/machine/overview/
Auguri a tutti!
Buon anno nuovo!
If you use Mozilla Firefox and you want to view video streaming with HTML5 embedded players, you may need to enable some video functionality into the firefox configuration.
For some reason obscure to me Mozilla Firefox will not play some HTML5 based video streaming, and the embedded player will probably fall back to Adobe Flash based streaming (that is what I don’t want since it’s closed source and it’s a very insecure application).
For example, youtube has a HTML5 based player that you could choose to use instead of flv. You can verify and enable HTML5 based streaming functionality of your browser navigating to https://www.youtube.com/html5.
In my case (Firefox 64 bit on Linux Debian) the tabs “Media Source Extensions”, “MSE & H.264” and “MSE & WebM VP9” are disabled by default.
If you want to enable those functionalities simply write “about:config” into the firefox navigation bar.
You will be alerted to pay attention to not modify things or your warranty will be broken.
Just ignore the warning and proceed.
Now, if you did not already, switch the following configuration parameters to true:
If you try to refresh the HTML5 based youtube player, you should hopefully have all video streaming tabs ready and enabled.
If you want, you can now switch the youtube default player to HTML5.
If you need to resize a iSCSI volume you need to:
I’ll skip the resize procedure on the target, because it depends on how it’s made (lvresize, dd, etc).
The procedure to rescan the volume on the initiator (open-iscsi) is very simple and can be accomplished online.
iscsiadm -m node -R
Then, you can grow the filesystem, if any (xfs_grofs, resize_reiserfs, resize2fs, depending on your fs type).
If you need to check which SSL/TLS protocol version is implemented by your webserver, you can issue the following command:
dino@dam2knb:~$ echo | openssl s_client -connect 10.38.46.137:8443 2>&1 | grep Protocol
Protocol : TLSv1.2
On one of the servers of one of my clients, a Solaris 5.8 sparc host, apache did not want to start.
It wrote the following error message on the error_log file:
cojo1@myserver $ cat error_log
[Wed Sep 30 12:24:11 2015] [error] (13)Permission denied: Cannot create SSLMutex
The problem, in my case, was about the permissions on /tmp.
Since these machines can be accessed by hundred people, someone thought well to change /tmp permissions to 0775. Everybody knows that if whould be 1777 instead.
The lack of both the sticky bit and write permissions to other did not make apache starting for non root users.
Hope this help someone.
