memcache+php扩展模块的安装

安装memcache

1、安装libevent

[root@localhost libevent-2.0.19-stable]#tar -zxvf libevent-2.0.19-stable.tar.gz

cd libevent-2.0.19-stable

[root@localhost libevent-2.0.19-stable]# ./configure --prefix=/usr

[root@localhost libevent-2.0.19-stable]#make

[root@localhost libevent-2.0.19-stable]#make install

2、测试libevent是否安装成功

[root@localhost libevent-2.0.19-stable]# ls /usr/lib |grep libevent

libevent-2.0.so.5

libevent-2.0.so.5.1.7

libevent.a

libevent_core-2.0.so.5

libevent_core-2.0.so.5.1.7

libevent_core.a

libevent_core.la

libevent_core.so

libevent_extra-2.0.so.5

libevent_extra-2.0.so.5.1.7

libevent_extra.a

libevent_extra.la

libevent_extra.so

libevent.la

libevent_openssl-2.0.so.5

libevent_openssl-2.0.so.5.1.7

libevent_openssl.a

libevent_openssl.la

libevent_openssl.so

libevent_pthreads-2.0.so.5

libevent_pthreads-2.0.so.5.1.7

libevent_pthreads.a

libevent_pthreads.la

libevent_pthreads.so

libevent.so

3、安装memcache

[root@localhost mem]# tar -zxvf memcached-1.2.2.tar.gz

[root@localhost mem]# cd memcached-1.2.2

[root@localhost memcached-1.2.2]# ./configure --with-libevent=/usr

[root@localhost memcached-1.2.2]# make

make all-recursive

make[1]: Entering directory `/home/mem/memcached-1.2.2'

Making all in doc

make[2]: Entering directory `/home/mem/memcached-1.2.2/doc'

make[2]: Nothing to be done for `all'.

make[2]: Leaving directory `/home/mem/memcached-1.2.2/doc'

make[2]: Entering directory `/home/mem/memcached-1.2.2'

if gcc -DHAVE_CONFIG_H -I. -I. -I. -DNDEBUG -I/usr/include -g -O2 -MT memcached-memcached.o -MD -MP -MF ".deps/memcached-memcached.Tpo" \

-c -o memcached-memcached.o `test -f 'memcached.c' || echo './'`memcached.c; \

then mv -f ".deps/memcached-memcached.Tpo" ".deps/memcached-memcached.Po"; \

else rm -f ".deps/memcached-memcached.Tpo"; exit 1; \

fi

memcached.c: In function ‘add_iov’:

memcached.c:582: error: ‘IOV_MAX’ undeclared (first use in this function)

memcached.c:582: error: (Each undeclared identifier is reported only once

memcached.c:582: error: for each function it appears in.)

make[2]: *** [memcached-memcached.o] Error 1

make[2]: Leaving directory `/home/mem/memcached-1.2.2'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/home/mem/memcached-1.2.2'

make: *** [all] Error 2

（make 时出错了）

-------------

解决方案：

[root@localhost memcached-1.2.2]# vim memcached.c

修改如下几行

56 /* FreeBSD 4.x doesn't have IOV_MAX exposed. */

57 #ifndef IOV_MAX

58 #if defined(__FreeBSD__)

59 # define IOV_MAX 1024

60 #endif

61 #endif

改成

56 /* FreeBSD 4.x doesn't have IOV_MAX exposed. */

57 #ifndef IOV_MAX

58 /*#if defined(__FreeBSD__)*/

59 # define IOV_MAX 1024

60 /*#endif*/

------------

再次编译

[root@localhost memcached-1.2.2]# make

[root@localhost memcached-1.2.2]# make install

安装完成后会把memcached放到 /usr/local/bin/memcached

4、测试是否成功安装memcached：

[root@localhost memcached-1.2.2]# ls /usr/local/bin/mem*

/usr/local/bin/memcached /usr/local/bin/memcached-debug

---------------------------------------------------

安装memcache的php扩展

安装libmemcached

[root@localhost mem]# tar -zxvf libmemcached-0.40.tar.gz

[root@localhost mem]# cd libmemcached-0.40

[root@localhost mem]# ./configure

[root@localhost mem]# make

[root@localhost mem]# make install

由于是64位cpu 32位的操作系统 memcached版本1.4.5

出现以下相关错误：

clients/ms_conn.o: In function `ms_get_udp_request_id':

/tmp/libmemcached-0.49/clients/ms_conn.c:194: undefined reference to `__sync_fetch_and_add_4'

clients/ms_conn.o: In function `ms_reconn_socks':

collect2: ld returned 1 exit status

make[2]: *** [clients/memslap] 错误 1

make[2]: Leaving directory `/tmp/libmemcached-0.49'

make[1]: *** [all-recursive] 错误 1

make[1]: Leaving directory `/tmp/libmemcached-0.49'

make: *** [all] 错误 2

修改相关参数编译

[root@niutian365 tmp]# ./configure --prefix=/usr/local/libmemcached --with-memcached --disable-64bit CFLAGS="-O3 -march=i686"

[root@niutian365 tmp]# make

[root@niutian365 tmp]# make install

先安装php，再安装扩展包

[root@localhost mem]# tar -zxvf memcache-1.5.tgz

[root@localhost mem]# cd memcache-1.5

[root@localhost mem]#/usr/local/php/bin/phpize

[root@localhost memcache-1.5]# ./configure --enable-memcache --with-php-config=/home/web/php/bin/php-config --with-zlib-dir

[root@localhost memcache-1.5]#make

[root@localhost memcache-1.5]#make test

[root@localhost memcache-1.5]#make install

运行/usr/local/webserver/php/bin/phpize时出现：
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
根据网上的解决办法是：

# cd /usr/src
# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz # tar -zvxf m4-1.4.9.tar.gz
# cd m4-1.4.9/
# ./configure && make && make install
# cd ../
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz # tar -zvxf autoconf-2.62.tar.gz
# cd autoconf-2.62/
# ./configure && make && make install

安装完成后提示：

[root@localhost memcache-1.5]# make install

Installing shared extensions: /home/web/php/lib/php/extensions/no-debug-non-zts-20090626/

修改php.ini

然后修改php.ini

把extension_dir = "./"

修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/"

并添加一行 extension=memcache.so

---------------

5、测试：

启动memcache

/usr/local/bin/memcached -d -m 10 -u root -l 10.103.20.135 -p 11211 -c 256 -P /tmp/memcached.pid

---

/usr/local/bin/memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

如果报这个错误就

把/usr/local/lib 加入到/etc/ld.so.conf下

然后执行 ldconfig

---

测试代码：

<?php

$memcache = new Memcache;

$memcache->connect('10.103.20.135',11211) or die ("Could not connect");

$version = $memcache->getVersion();

echo "Server's version: ".$version."<br/>\n";

$tmp_object = new stdClass;

$tmp_object->str_attr = 'test';

$tmp_object->int_attr = 123;

$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");

echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

$get_result = $memcache->get('key');

echo "Data from the cache:<br/>\n";

var_dump($get_result);

?>
