Installing memcached On CentOS/RHEL

Using info from CentOS forums, Sunny Walia and Ryan Boren, here’s how I got memcached running on my Dotster VPS:

Install libevent:

``` wget tar zxvf libevent-1.3e.tar.gz cd libevent-1.3e   ./configure make make install ```

Install memcached

``` wget tar zxvf memcached-1.2.5.tar.gz cd memcached-1.2.5   ./configure make make install ```

We will start the server to use 30 megs of ram (-m 30), listen on ip (-l and run on port 11211 (-p 11211) as user ‘nobody’ (-u nobody):

``` memcached -u nobody -d -m 30 -l -p 11211 ```

Get an error?

``` memcached: error while loading shared libraries: cannot open shared object file: No such file or directory ```

Show it the path to the library:

``` LD_LIBRARY_PATH=/usr/local/lib export LD_LIBRARY_PATH ```

JSON on RHEL & PHP 5.1.6

Stuck with PHP 5.1.6 on RHEL or even CentOS (and a sysadmin who insists on using packages)? Need JSON? I did. The solution is easy:

yum install php-devel<br /> pecl install json

The pecl install failed when it hit an 8MB memory limit, and I was clueless about how to fix it until I learned that the pecl installer ignores the php.ini. Turns out the best solution is to use the pear installer (which does follow php.ini settings):

pear install pecl/json
