    WordPress Migrations - Moving WordPress to Another Server WordPress Migrations - Moving WordPress to Another Server Presentation Transcript

    • You may have to do one or all of the following to move a WordPress site from one server/folder to another. Physically relocate the files (PHP, images etc.) Physically relocate the database (SQL) Reconfigure WordPress to point to new database Rename URLs in database from old domain/folder to new domain/folder
    • You could move them one-by-one using FTP.
    • BUT that would take ages..
    • Pack entire WordPress site into one archive • Zip, Gzip, lhz, 7z …whatever The method: Download the archive to local machine then upload and unpack at new location
    • Command line for SSH: tar –zcvrf archive.tar.gz ./ Note: tar by itself doesn’t compress -z = gzip -c = create -v = verbose -f = file -r = recursive Unpacking: tar –zxvf archive.tar.gz (-x = extract)
    • File Manager on cPanel: Compress/Uncompress
    • FTP = “File Transfer Protocol” – PRO: Has been around since dawn of Interwebs – PRO: Vastly supported – CON: Two channels. One for data, one for control. Bit of overhead – CON: No encryption. None. Nadda. Tiddly Squat. Zero! N O T H I N G Try to avoid using FTP where possible. However, most shared hosting plans do not support secure FTP WTF is that all about?
    • Two completely different methods! FTPS = “Secure FTP” Port 990 Uses two data streams. One for data + one for control SSL encryption. Widely supported. SFTP = “SSH File Transfer Protocol” Port 22 Uses one data stream for both control and data Requires SSH keys management. More secure. Pros/Cons: https://www.eldos.com/security/articles/4672.php?page=all
    • Command line :-P WinSCP (free) Has a global password to protect accounts PuTTY (free) SSH client IDEs PHPStorm and Dreamweaver have built in FTP clients
    • 1. At old location, pack existing site into a compressed archive file 2. Download archive file to local machine 3. FTP archive file up to new location (securely if possible) 4. Unpack archive file at new location Congrats - Your WordPress site files are now at the new location.
    • Two Considerations before attempting to move the database 1. “Am I moving the database to a new database server?” Will mostly be yes. 2. “Am I moving the site to a new domain or folder structure?” e.g. myolddomain.com  mynewdomain.com mydomain.com/wordpress  mydomain.com/blog If so, you will also need to rename the old domain URLs that are stored in the database, to your new domain
    • URLs in your content or links to images/resources on your posts and pages are stored in the database. Some, URLs will be stored along with other related information (e.g post/media ID, attributes) – an array of information Arrays are stored in the DB as serialized data. e.g. {s:26:”http://www.limecanvas.com/”} s:26 = number of characters in the string By simply renaming URLs in the SQL file using a text editor, the number of characters in the string will be incorrect and that will cause data issues. You need to update both.
    • Free version • https://wordpress.org/plugins/wp-migrate-db/ • Renames URLs in serialized data • Save DB file as SQL or sql.gz Paid version • https://deliciousbrains.com/wp-migrate-db-pro/ • Pull/Push directly to DB server • Detects environmental limitations to avoid failures • Select whatever tables you want to migrate • Support • Sync media files
    • Upload the sql.gz file that was generated by WP Migrate DB
    • PHPMyAdmin or PHP environment may have upload limitations. Three tricks: 1. Use SSH mysql –u username –p database_name < file.sql or for a .sql.gz zcat file.sql.gz | mysql -u username –p database_name 2. Use BigDump script http://www.ozerov.de/bigdump/ 3. Split SQL file into manageable chunks Not recommended. Easy to break SQL statements.
    • 1. Use WP Migrate DB Rename old domain to new domain 2. Generate .sql.gz file 3. Load into blank DB using PHPMyAdmin
    • Last thing to do is to tell WordPress where the database is Edit the wp-config.php file define('DB_NAME', 'DBNAME'); define('DB_USER', 'DBUSERNAME'); define('DB_PASSWORD', 'DBPASSWORD'); define('DB_HOST', 'localhost');
    • Read Japh’s “Migrating a Site Quickly with SSH and WP-CLI” SSH – scp ./* wil@newdomain.com:~/limeca/wordpress WP-CLI “a command line interface for WordPress” – wp db export - l gzip > database.sql.gz – wp core download – gunzip < database.sql.gz | wp db import – wp search-replace olddomain.com newdomain.com – then edit the wp-config.php file
    • XCloner Plugin (free) http://www.xcloner.com/ OK – if you’re not changing domain or URL structure i.e. “cloning” BackupBuddy (paid) http://ithemes.com/purchase/backupbuddy/ Using the “Move” feature. Deploy to a new domain. Git (free) http://git-scm.com/ From “master” branch, pull on or push to server. Doesn’t do the DB though on its own (use hooks)
    • When moving your site watch out for… .htaccess file (hidden file in your site root folder) – This file is used for caching and permalinks. It may contain references to your old domain/URL structure. If in doubt, don’t move it to the new server and let WordPress create a new one by saving your Permalinks settings in the moved site. Caching/Security Plugins – These may also use the .htaccess file to add rewrite rules which may contain the old domain/URL structure. Disabled them before the move and then activate them again on the new server.
