64位机器上安装memcache
机器ip为192.168.6.210,64位centOS51,首先下载到memcached和libevent
memcache需要libevent的支持
#cd /usr/local/src/
# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
2,安装libevent
# tar zxvf libevent-1.2.tar.gz -C /usr/local/
# cd libevent-1.2
# ./configure --prefix=/usr/local
# make
# make install
查看是否安装成功，进行确认：
# ls -al /usr/local/lib | grep libevent
在210上出现如下信息，安装成功：
lrwxrwxrwx 1 root root 21 Mar 22 18:41 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3
-rwxr-xr-x 1 root root 262475 Mar 22 18:41 libevent-1.2.so.1.0.3
-rw-r--r-- 1 root root 430228 Mar 22 18:41 libevent.a
-rwxr-xr-x 1 root root 811 Mar 22 18:41 libevent.la
lrwxrwxrwx 1 root root 21 Mar 22 18:41 libevent.so -> libevent-1.2.so.1.0.3
3,安装memcached
安装memcached时，需要指定libevent的安装位置：
# tar zxvf memcached-1.2.0.tar.gz -C /usr/local
# cd memcached-1.2.0
# ./configure --with-libevent=/usr/local
# make
# make install
安装完成后会将memcached放到/usr/local/bin/memcached,查看是否安装成功：
# ls -al /usr/local/bin/mem*
出现如下信息:
-rwxr-xr-x 1 root root 114673 Mar 22 18:52 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 120092 Mar 22 18:52 /usr/local/bin/memcached-debug
安装完成了，现在我们看一下memcache的帮助：
# /usr/local/bin/memecached -h
这时候出现了如下错误：
memcached: error while loading shared libraries: libevent-1.2.so.1: cannot open shared object file: No such file or directory
下面说下修复过程：
# LD_DEBUG=libs memcached -v 查看memcached的libs的路径
在210上出现了如下信息：
5427: find library=libevent-1.2.so.1 ; searching
5427: search cache=/etc/ld.so.cache
5427: search path=/lib64/tls/x86_64:/lib64/tls:/lib64/x86_64:/lib64:/usr/lib64/tls/x86_64:/usr/lib64/tls:/usr/lib64/x86_64:
/usr/lib64 (system search path)
5427: trying file=/lib64/tls/x86_64/libevent-1.2.so.1
5427: trying file=/lib64/tls/libevent-1.2.so.1
5427: trying file=/lib64/x86_64/libevent-1.2.so.1
5427: trying file=/lib64/libevent-1.2.so.1
5427: trying file=/usr/lib64/tls/x86_64/libevent-1.2.so.1
5427: trying file=/usr/lib64/tls/libevent-1.2.so.1
5427: trying file=/usr/lib64/x86_64/libevent-1.2.so.1
5427: trying file=/usr/lib64/libevent-1.2.so.1
5427:
memcached: error while loading shared libraries: libevent-1.2.so.1: cannot open shared object file: No such file or directory
现在应该记录下来libs的位置，我选择的是trying file=/usr/lib64/libevent-1.2.so.1
现在我们利用这个来做个符号链接:
# ln -s /usr/local/lib/libevent-1.2.so.1 /usr/lib64/libevent-1.2.so.1
下面我们继续使用memcached -h做下测试，终于出现了如下信息:
memcached 1.2.0
-p <num> port number to listen on
-s <file> unix socket path to listen on (disables network support)
-l <ip_addr> interface to listen on, default is INDRR_ANY
-d run as a daemon
-r maximize core file limit
-u <username> assume identity of <username> (only when run as root)
-m <num> max memory to use for items in megabytes, default is 64 MB
-M return error on memory exhausted (rather than removing items)
-c <num> max simultaneous connections, default is 1024
-k lock down all paged memory
-v verbose (print errors/warnings while in event loop)
-vv very verbose (also print client commands/reponses)
-h print this help and exit
-i print memcached and libevent license
-b run a managed instanced (mnemonic: buckets)
-P <file> save PID in <file>, only used with -d option
-f <factor> chunk size growth factor, default 1.25
-n <bytes> minimum space allocated for key+value+flags, default 48
说明memcached安装成功。（应该是机器是64位的原因，所以将so文件放到了lib64下面，而不是lib下面，使得memcached找不到了so文件）
下面，我们来启动一个Memcached的服务器端：
# /usr/local/bin/memcached -d -m 10 -u root -l 192.168.0.200 -p 12000 -c 256 -P /tmp/memcached.pid
4，安装memcache PHP模块
# tar vxzf memcache-1.5.tgz -C /usr/local/
# cd memcache-1.5
# /usr/local/php/bin/phpize
# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir
# make
# make install
之后会提示:
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/
把这个记住，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
然后重起apache，查看phpinfo(),如果有memcache模块，则说明安装成功
