Install and verify memcached and memcached

1. Install libevent

Down: http://www.monkey.org

My online drive down: http://pan.baidu.com/s/1qW8syZi

[Root @ luozhonghua memcachedsource] # tar-zxvf libevent-1.4.13-stable.tar.gz

[Root @ luozhonghua memcachedsource] # cd libevent-1.4.13-stable

[Root @ luozhonghua memcachedsource] #./configure -- prefix =/usr

[Root @ luozhonghua memcachedsource] # make & make install

#./Configure -- prefix =/usr & make install

Pay attention to specifying -- prefix, which will be necessary when memcached is configured later.

 

2 install memcached

Down: http://www.monkey.org

My online drive down: http://pan.baidu.com/s/1qW8syZi

[Root @ luozhonghua memcachedsource] # tar-zxvf memcached-1.4.5.tar.gz

[Root @ luozhonghua memcachedsource] # cd memcached-1.4.5

[Root @ luozhonghua memcached-1.4.5] #./configure -- with-libevent =/usr/lib

[Root @ luozhonghua memcached-1.4.5] # make & make install

#./Configure -- with-libevent =/usr/lib & make install

You must specify the libevent path here. Otherwise, the so file cannot be found at startup!

3> Start memcached

#/Usr/local/bin/memcached-m 32 m-p 11211-d-u root-P/var/run/memcached. pid-c 256-vv

/Usr/local/bin/memcached-d-m 512-p 11211-u root-c 256-P/var/run/memcached. pid

4> disable memcached

Kill-9 'cat/var/run/memcached. Pi'

Note: If the value of 'cat/var/run/memcached. Pi' is cached last time, the pid value = 7787 can be directly found.

 

5> Test

Install the memcached extension of PHP in linux

First, determine whether it is memcache or memcached.
Telnet successfully proves that memcache is successfully installed.
Phpinfo shows memcached, Which is okay.

But you said
It is useless to use the official PHP file for memcached testing. The Error 500 is displayed on the page.
I wonder if you are using such code.
<? Php
$ Mem = new Memcache;
$ Mem-> connect ("192.168.x.y", 11211) or die ("cocould not connect ");

$ Mem-> set ('key', 'This is a test! ', 0, 60 );
$ Val = $ mem-> get ('key ');
Echo $ val;
?>

Pay attention to the first line .. $ Mem = new Memcache;

If your server supports memcached, memcached is displayed in phpinfo.
For memcache, only memcache is displayed.

Memcached is an extension of php.
Therefore, if you use new memcache To Go To The instance memcached, it will take 500 of the total output.

CentOS6 Memcached cannot be automatically started upon startup. How can I manually enable the discuz Memca?

In a daze, reply, and end of work ~ View Original post>
