When configuring a website to work with different languages on a Linux server, the mbstring extension will need to be installed on the server for the website functionality to work. The mbstring extension is what php uses to parse different language encoding’s. This article will explain how to install the mbstring extension through shell.
Check your server for the mbstring extension through Linux Command line. Running the following command will display the mbstring information on your server.
If the results show nothing, then the mbstring is not installed on the server. The next section will explain how to install the mbstring extension through shell with Root access.
The mbstring extension can be installed through shell by using Easy Apache. The following steps will explain how to install mbstring through Easy Apache.
- Shell (SSH) into the server.
- Start a screen session by typing the following.
root@vps#### [~]# screen -S screenname
You can check the screen by typing the following.
root@vps#### [~]# screen -ls
There is a Screen on:
22342.upgrade (Attached)
1 Socket in /var/run/screen/S-root
The screen session will allow the server to run in the background. This is to prevent the process from being interupted during the recompile process. If the window is closed, The process can still be found on the server. Otherwise, the process will be killed which could break the server.
