Title: Instaling two wordpress ?! Last modified: August 20, 2016 --- # Instaling two wordpress ?! * [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/) * Hi * I already got one wordpress installed in domain.com/subdomain1 and in the function. php – I changed the database name to “wp1” * Now, could I do ahead and do similar thing to /subdomain2 and change it to “ wp2” ?! * Will this make sure that two different database tables are being used? In other words: will this cause any issue with my other installed WP ? * Cheers Viewing 10 replies - 1 through 10 (of 10 total) * Thread Starter [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322151) * “… and in the function.php – I changed the database name to “wp1” of course this was done prior (before) I run the installation etc * Just for clarification 😀 * [Rev.

There should be no conflict file structure / URL wise * As for the database, you have 2 options. You can have an individual database for each install, but it sounds like you want to use 1 database * That also works well, you just need to use a different prefix in the database for the second install, as you have suggested — You should be able to setup that prefix during installation, I believe WP asks for a DB prefix during the install phase * Thread Starter [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322189) * Hi * Thanks! * Yeh, could I not create a different database table and specify it so in the function.php? * Reason for that is so it wont mess up my other wp database table 🙂 * [Rev. Voodoo](https://wordpress.org/support/users/rvoodoo/) * (@rvoodoo) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322196) * functions.php in your theme? * I think the issue is, if you are to the point of editing your theme files, WP is already installed – would that not be true? So the tables are already set up. * If you handle the prefix at installation time, it’s done from the start. * I personally have about 10 WP sites running on my server, and I prefer to have 1 DB per install. It just keeps everything individual. That’s just my preference * Thread Starter [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322197) * Yeh, thats what I am saying = 1 DB per install. in my cPanel there is the MySQL option, where you can go ahead and create many DB TABLES. * Cannot recall the WP installation process asking you if wanting to create a new table etc?! * [Rev. Voodoo](https://wordpress.org/support/users/rvoodoo/) * (@rvoodoo) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322198) * Ah… OK. You want the individual tables. That’s the way I prefer. * So yeah. You actually tell WP what table to use in the wp-config.php file for each install. * So you already have 1 installation in one table. * You now make your new table through phpmyadmin, or whatever cpanel tool you have available to you. * You can then input the new details on installation, or manually edit wp-config. php of the new install. * [http://codex.wordpress.org/Installing_WordPress#Step_2:_Create_the_Database_and_a_User](http://codex.wordpress.org/Installing_WordPress#Step_2:_Create_the_Database_and_a_User) Info here may help * The info that you enter into wp-config.php (or enter into the setup screen) will point WP to use the new database * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322199) * **Edit:** The Right Reverend Voodoo replied faster than I did. 😉 * > in my cPanel there is the MySQL option, where you can go ahead and create many > DB TABLES. * You can use one DB and just have a different `$table_prefix` for the different installations via your `wp-config.php` file. * ``` /** * WordPress Database Table prefix. * * You can have multiple installations in one database if you give each a unique * prefix. Only numbers, letters, and underscores please! */ $table_prefix = 'wp_'; ``` * They’ll need to be in different independent directories but that does work. * I’m avoiding the mention of Multisite at the moment. 😉 * Thread Starter [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322200) * Jan * Yeh both WP will be on different directories anyway. And yes, I was going to use a different table_prefix * But was not clear about the DB Table. In simple terms, both WP using ONE DB TABLE but with different prefix?! * I just thought, if anything happens then it will mess up the database of my first wp (where I have over 200 pots lol) * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322201) * The different table prefixes means different tables. * If the two installs have different table prefixes (they should) they you will not be sharing the same tables. Just the same database. * Thread Starter [Bucki](https://wordpress.org/support/users/bucki/) * (@bucki) * [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322203) * Great 🙂 * That rests my mind now 😀 * Cheers all Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Instaling two wordpress ?!’ is closed to new replies. * In: [Everything else WordPress](https://wordpress.org/support/forum/miscellaneous/) * 10 replies * 3 participants * Last reply from: [Bucki](https://wordpress.org/support/users/bucki/) * Last activity: [13 years, 5 months ago](https://wordpress.org/support/topic/instaling-two-wordpress/#post-3322203) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
