linux下安装配置使用memcache,memcached,libevent(后有ubuntu的memcache安装)

1: 还是下载

Memcache是用C编写的，要用到C的libevent来处理接口

点击下载memcached-1.4.0.tar.gz

下载libevent-2.0.13-stable.tar.gz

下载memcache-3.0.6.tgz

我下载到了/root/Downloads

2:解压编译

a：先安装libevent

#cd /Downloads
#tar zvxf libevent-2.0.13-stable.tar.gz
#cd libevent-2.0.13-stable
#./configure --prefix=/usr
#make
#make install

查看下安装是否成功

# ls -al /usr/lib | grep libevent

b. 安装memcached(用的root权限,下同)

#cd ..
#tar zxvf memcached-1.4.0.tar.gz
#cd memcached-1.4.0
# ./configure --with-libevent=/usr 
# make
# make install

注意编译配置./configure --with这里是两个 这里不要错了

检查是否成功

hihihi@TP-Tablet:~$ ls -la /usr/local/bin/*mem*
-rwxr-xr-x 1 root root 257899 2011-09-18 18:10 /usr/local/bin/memcached

现在使用memcached,输入

 /usr/local/bin/memcached -d -m 100 -u root -l 127.0.0.1 -p 11211 -c 256 -P tmp/memcached.pid

(参数说明:/usr/local/bin/memcached 是memcached编译后所在的地址 -d 是一个守护进程占用一个进程, -m 是分配给memcached的内存,单位MB, -u 是启动memcached的用户, -l 是监听的服务器地址,这里可以设置多台memcache服务器监听同一个IP作成集群, -p 是端口号,默认是11211,实际企业生产中建议修改, -c是运行时最大的并发连接数,默认1024, -P是设置保存memcached的pid文件. 其他参数可以用memcached -h获得帮助)

进入了memcached,随便输入下 比如输入stats显示状态,输入version显示版本.

 也可以telnet 127.0.0.1 11211 连入,其他操作一样.

要关掉memcached服务,

killall -0 memcached

c. 安装memcache

#cd ..
#tar vxzf memcache-3.0.6.tgz
#cd memcache-3.0.6
#/usr/local/php/bin/phpize
#./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
#make
#make install
#gvim /etc/php5/apache2/php.ini

修改php.ini中的extension_dir = “./”

extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/”

添加

extension=memcache.so

3: 启动和关闭

#/usr/local/bin/memcached -d -m 128 -u root -l 127.0.0.1 -p 11211 -c 256 -P /var/temp/memcached.pid
#kill `cat /var/temp/memcached.pid` 或者#killall memcached

重启apache 

sudo /etc/init.d/apche2 restart 

4：测试

新建一个testMem.php文件

< ?php
$mem = new Memcache;
$mem->connect(“127.0.0.1″, 11211);
$mem->set(‘key’, ‘This is a test!’, 0, 60);
$val = $mem->get(‘key’);
echo $val;
?>

This is a test!

5: ubuntu/debian 。

a.直接sudo memcached

sudo apt-get install memcached

启动

memcached -d -m 128 -p 11211 -u root -l 127.0.0.1

b.sudo memcache

sudo apt-get install php5-memcache

 sudo gvim /etc/php5/conf.d/memcache.ini
; uncomment the next line to enable the module
extension=memcache.so

[memcache]
memcache.dbpath="/var/lib/memcache"
memcache.maxreclevel=0
memcache.maxfiles=0
memcache.archivememlim=0
memcache.maxfilesize=0
memcache.maxratio=0

c.如果提示需要libevent

sudo apt-get install libevent-dev

然后重启下apache查看phpinfo就可以看见memcache了
