This document describes how to install and deploy the memcached service in linux.
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.
Target: x86_64-redhat-linux
Configured :.. /configure -- prefix =/usr -- mandir =/usr/share/man -- infodir =/usr/share/info -- enable-shared -- enable-threads = posix -- enable-checking = release -- with-system-zlib -- enable-_ cxa_atexit -- disable-libunwind-exceptions -- enable-libgcj-multifile -- enable-versions ages = c, c ++, objc, obj-c ++, java, fortran, ada -- enable-java-awt = gtk -- disable-dssi -- enable-plugin -- with-java-home =/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre -- with-cpu = generic -- host = x86_64-redhat-linux

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
Libevent.

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

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
