Setup Memecached on RHEL6

This will setup memcached to allow connections from localhost (127.0.0.1)

1. sudo vim /etc/sysconfig/memcached
   • PORT=”11211″
   • USER=”memcached”
   • MAXCONN=”1024″
   • CACHESIZE=”512″
   • OPTIONS=”-l 127.0.0.1″
     • You can use the OPTIONS line to add any other memcached command line parameters. For ex. above I want to have it listen on the private ip 127.0.0.1 (borrowed from MDLog:/sysadmin)
2. I had to turn selinux off to allow httpd scripts to connect to the network, i think there might be a better way of doing this but i’m not sure yet.
   • sudo setenforce 0

Setup Oracle/PHP connection on RHEL6

This is similar to my post on how to do this on Ubuntu, but it’s a little different but a lot easier on Redhat (don’t tell anyone i said that)

1. download the rpm’s for the oracle instant client (basic & sdk) from http://www.oracle.com/technetwork/topics/linux-amd64-093390.html
2. copy the rpm’s to your server and install them (sudo rpm -i filename.rpm)
3. sudo yum install php-devel
4. • You’ll need this for phpize
5. sudo yum install php-pear gcc
6. sudo pecl install oci8
   1. use default for “Please provide the path to the ORACLE_HOME directory. Use ‘instantclient,/path/to/instant/client/lib’ if you’re compiling with Oracle Instant Client [autodetect] :”
   2. Note the last line “You should add “extension=oci8.so” to php.ini”
7. create a file /etc/php.d/oci8.ini with the contents: extension=oci8.so, see other files in this directory as examples
8. sudo service httpd restart
