How to Install PECL Memcache in WHM / CentOS

You can run these commands to install PECL memcache (not memcached).
However, this memcache will work with memcached.

wget http://pecl.php.net/get/memcache-3.0.8.tgz
tar xvfz memcache-3.0.8.tgz
cd memcache-3.0.8
phpize
./configure
make
make install

Take note of the php extensions directory that memcache is installed in.
Mine is: /usr/local/lib/php/extensions/no-debug-non-zts-20020429/

Then add this line to your php.ini

extension="/usr/local/lib/php/extensions/no-debug-non-zts-20020429/memcache.so"

MySQL Table “In Use” Repair

Recently when i optimized some mysql tables from phpmyadmin, some of the tables were “locked” and showed as “in use” on phpmyadmin. The tables could not be used, read, etc. So the script was stopped working.
I have tried to repair / check / analyze from phpmyadmin but i couldn’t repair it.
So i tried to repair the mysql tables from SSH.

Go to your database directory. Usually it is located on
/etc/var/lib/mysql/YOUR_DATABASE_NAME/

So use this command first
cd /etc/var/lib/mysql/YOUR_DATABASE_NAME/

Next, use this command
myisamchk --safe-recover --force YOUR_TABLE_NAME

And the MySQL table should be repaired now.
