linux安装memcacehed

    1、wget http://www.danga.com/memcached/dist/memcached-1.2.5.tar.gz

    2、wget http://www.monkey.org/~provos/libevent-1.2.tar.gz

    3、先安装libevent

         tar zxvf libevent-1.2.tar.gz

         cd libevent-1.2

         ./configure –prefix=/usr

         make && make install

     4、测试libevent是否安装成功：

         # ls -al /usr/lib | grep libevent

         lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3

         -rwxr-xr-x 1 root root 263546 11?? 12 17:38 libevent-1.2.so.1.0.3

         -rw-r–r– 1 root root 454156 11?? 12 17:38 libevent.a

         -rwxr-xr-x 1 root root 811 11?? 12 17:38 libevent.la

         lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3

         还不错，都安装上了

      5、安装memcached服务器，同时需要安装中指定libevent的安装位置：

         # cd /tmp

         # tar zxvf memcached-1.2.0.tar.gz

         # cd memcached-1.2.0

         # ./configure –with-libevent=/usr

         # make

         # make install

         如果中间出现报错，请仔细检查错误信息，按照错误信息来配置或者增加相应的库或者路径。

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

       6、测试是否成功安装memcached：

           # ls -al /usr/local/bin/mem*

           -rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached

           -rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug

       7、安装MemacachePHP扩展

           tar vxzf memcache-2.2.1.tgz

           cd memcache-2.2.1

           /usr/local/php/bin/phpize

           ./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir

           make

           make install

       8、把php.ini中的extension_dir = “./”修改为

            extension_dir = “？？？”（最后安装好的地址）

       9、添加一行来载入memcache扩展：extension=memcache.so

       10、安装Memacached扩展模块

             wget  https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

             tar -zxf libmemcached-1.0.18.tar.gz 

             ./configure --prefix=/usr/local/libmemcached --with-memcached

             make  &&  make install

             wget http://pecl.php.net/get/memcached-2.2.0.tgz

              tar -zxf memcached-2.2.0.tgz

              cd memacached-2.2.0

              phpize

              //先看看php-config路径对不对

              ./configure --with-php-config=/usr/bin/php-config  --with-libmemcached-dir=/usr/local/libmemcached

              make && make install

 

       安装完毕：php -m    查看一下

 

        /usr/local/memcached/bin/memcached -u root -m 512 -d        //linux 上开机命令     

                    -u    开启者身份

                    -m   运行内存大小（以兆为单位）

                    -d    指定后台运行

        ps aux|grep mem              //查看memcached当前 运行状态

 

         pkill -9 memcached           //杀死 memcached 进程
