This document describesLinuxInstall and deploy the memcached service in the environment

Operating System:

Red Hat Enterprise Linux Server release 5.4 (Tikanga)

Memory: 4 GB

1. Verify that gcc is installed

Execute gcc-v on the command line to check whether the gcc version is output. If no gcc version is available, notify the O & M personnel to install

Appendix: output during normal gcc Installation

[Root @ tyff000001 bin] # gcc-v

Using built-in specs.

2. Download The memcached source code package

Http://code.google.com/p/memcached/downloads/list
Currently, memcached-1.4.12.tar.gz is installed.

3. Download The libevent package

Http://libevent.org/
Libevent-2.0.16-stable.tar.gz

4. decompress the memcached and libevent packages.

Upload the memcached-1.4.12.tar.gz and libevent-2.0.16-stable.tar.gz packages to the server.
For example,/home/kevin/software/
Switch the command line to this directory and run
Tar-zxvf memcached-1.4.12.tar.gz
Tar-zxvf ibevent-2.0.16-stable.tar.gz
Decompress the two packages

5. Install

• Install ibevent

Command Line enter the decompressed libevent directory/home/kevin/software/libevent-2.0.16-stable
Run the following commands in sequence:
./Configure -- prefix =/usr/
Make
Make install # (note that the user running this command must have the permission to install the software-apply for a root user)
Verify Installation
Ls/usr/lib | grep libevent
If the installation is correct, there will be output
Libevent-2.0.so.5
Libevent-2.0.so.5.1.4

• Install the memcached Service

Switch to the memcached extract directory
Cd/home/kevin/software/memcached-1.4.12
Run the following commands in sequence:
./Configure -- prefix =/usr/local/memcached -- with-libevent =/usr/
Make
Make install
Verify that memcached is successfully installed
Ls-al/usr/local/memcached/bin
Tip:

Memcached startup parameters

-D option is to start a daemon,

-M indicates the amount of memory allocated to Memcache. The unit is MB. Here it is 3072 MB (3 GB ),

-U is the user who runs Memcache. Here is kevin,

-L is the IP address of the listener server.

-P is the port for Memcache listening. It is not specified as 11211 by default, preferably over 1024.

-The c option is the maximum number of concurrent connections. The default value is 1024, which is determined based on the load of your server.

-P is the pid file for saving Memcache. Here I am saving it in/tmp/memcached. pid
