Tips & Tricks : Yii framework update issue

-

When Yii-based project doesn’t want to update, there might be missing component.

Once you add one plugin everything goes back to normal.

[root@arb-srv-01 easyforms]# composer update
Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- Installation request for yiisoft/yii2 2.0.7 -> satisfiable by yiisoft/yii2[2.0.7].

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Tips & Tricks : MariaDB on CentOS : Installation and first configuration

-

In order to install MySQL/MariaDB database engine on CentOS follow these:

[root@localhost ~]# yum install mariadb-server
[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# systemctl start mariadb

[root@localhost ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.


Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
[root@localhost ~]#

Recommended is also to deploy phpMyAdmin, if you don’t have any issues with installing web server on same box as database.

That will simplify MySQL/MariaDB management.

Tips & Tricks : CentOS firewalld : open port

-

Once you install CentOS 7, by default firewalld will block almost all network traffic.

In order to open ports for certain services you can easily reconfigure firewall using firewall-cmd command.

[root@localhost firewalld]# firewall-cmd --get-active-zones
public
  interfaces: eno16777728
[root@localhost firewalld]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost firewalld]# firewall-cmd --reload
success

Example contains port 80, however you can open any port using same method.
It is worth to check zones configured on your machine and make sure you open port in proper zone where service should be enabled.
