Memcached Installing Notes on Linux

The first kind of yum Mode installation

Memcached supports many platforms: Linux, FreeBSD, Solaris, Mac OS, or Windows.

The first step Linux system installation memcached, first install the Libevent library

Ubuntu/debian

sudo apt-get install libevent libevent-deve automatic Download installation (Ubuntu/Debian)

Redhat/fedora/centos

Yum Install libevent libevent-deve 

To see if the Libevent installation was successful



Step Two install memcached

Ubuntu/debian

sudo apt-get install memcached  

Redhat/fedora/centos

Yum Install memcached

Step three: Memcached-h appears the following instructions succeeded

Fourth Step start Memcache
Memcached-m 50-p 11212-d-C 8192-u Root

Memcached-m 500-p 11211-d-C 8192-u Root

To see if memcached starts execution: Netstat-lntup|grep mem

That means memcached is starting up.

If you start multiple instances, use memcached-m 500-p 11212-d-C 8192-u Root

You can adjust the lower port.

Start Memcache Common parameters

-P <num> Set TCP port number (default is not set to: 11211)

-U <num> UDP Listening port (default: 11211, 0 o'clock off)

-L <ip_addr> Bind address (default: All allowed, regardless of internal or external network or local replacement IP, there is a security risk, if set to 127.0.0.1 can only be native access)

-d runs in daemon mode

-U <username> bindings use specified for running processes <username>

-M <num> allowable maximum memory usage, Unit m (default: MB)

-P <file> writes the PID to the file <file>, which enables fast process termination behind and needs to be used with-D

The second way of installation can of course be installed by using a compiled installation

First step: Install Libevent

1. First Use: Ls-al/usr/lib | grep libevent to see if it is installed, and if it is installed and the version is less than 1.3, uninstall it first by: Rpm-e Libevent-nodeps.

2. Download the Libevent installation package: libevent-1.4.13-stable.tar.gz, then unzip.

3. Switch to the Libevent home directory after decompression: CD libevent-1.4.13-stable

4. Perform the following sequence:

1. ./CONFIGURE–PREFIX=/USR (or./configure--program-prefix=/usr)
2. Make
3. Make install

Attention:
1) root permission may be required to perform the make install.

2) Libevent will be installed to/usr/lib or/usr/local/lib

5. Test whether the Libevent is installed successfully: Ls-al/usr/lib | grep libevent (or Ls-al/usr/local/lib | grep libevent)
A similar result indicates that the installation was successful:

Step Two: Install memcached

Source Code Installation

Download the latest version of memcached from its official website (http://memcached.org).

wget http:Memcached.org/latest Download the latest versionTar-zxvf memcached-1.x.  X.  Tar.  GZ Decompression Source cd memcached-1.x.  X

Tar-ZXVF memcached-1.x.< Span class= "PLN" >x.. GZ  decompression source CD memcached-1.x x  Enter directory ./configure Span class= "pun" >--prefix=/usr/local< Span class= "pun" >/memcached  config make & & make test  compile sudo make install  Installation   

Whether it is a compile installation or Yum installation after installing memcached to see if it is installed before starting to see if the installation is used: which memcached jumps to the memcached installation directory

Then execute: The results of the Memcached-h show that the installation was successful

If you do not see the above interface instructions, you cannot find the libevent

Solution machine is find/-name "libevent-1.4.so.2"

If it is compiled and installed memcached execution memcached-h will report the following error

Vi/etc/ld.so.conf

Join

/usr/local/lib

Save

And then ldconfig to make it effective.

Step three: Memcached-h appears the following instructions succeeded

Fourth Step start Memcache

Memcached-m 500-p 11211-d-C 8192-u Root

To see if memcached starts execution: Netstat-lntup|grep mem

That means memcached is starting up.

If you start multiple instances, use memcached-m 500-p 11212-d-C 8192-u Root

You can adjust the lower port.
