#1. How to reset the post ID increment WordPress
Go to phpMyAdmin, make sure your that on my
wp_postsmeta tables are only information about the 10 real posts IDs, from the
mysite/wp-admin/export.php I exported all the posts (10 of them), then run the following SQL query on phpMyAdmin.
DELETE FROM wp_posts;
DELETE FROM wp_postmeta;
TRUNCATE TABLE wp_posts;
TRUNCATE TABLE wp_postmeta;
#2. Linux Command to unzip/extract a .tar.gz file
man tar for more information, but this command should do the trick:
tar -xvzf community_images.tar.gz
To explain a little further, tar collected all the files into one package,
community_images.tar. The gzip program applied compression, hence the gz extension. So the command does a couple things:
f: this must be the last flag of the command, and the tar file must be immediately after. It tells tar the name and path of the compressed file.
z: tells tar to decompress the archive using gzip
x: tar can collect files or extract them.
xdoes the latter.
v: makes tar talk a lot. Verbose output shows you all the files being extracted.
tar -xvf <.tar file> or <.tar.xz file>
tar -xzvf <.tar.gz file>
tar -xjvf <.tar.bz2 file>
#3. How do I import an SQL file using the command line in MySQL?
I have a
.sql file with an export from
phpMyAdmin. I want to import it into a different server using the command line.
mysql -u username -p database_name < file.sql
Check MySQL Options.
Note-1: It is better to use the full path of the SQL file
--triggers to keep the routines and triggers of original database. They are not copied by default.
Note-3 You may have to create the (empty) database from mysql if it doesn’t exist already and the exported SQL don’t contain
CREATE DATABASE (exported with
-n option), before you can import it.
