CentOS 上安装Memcached笔记

环境：CentOS 5,X64
软件包：libevent-1.4.10(http://www.monkey.org/~provos/libevent/)
、memcached-1.2.8(http://www.danga.com/memcached/dist/)
说明：安装memcached前需要先安装libevent

开始：
安装libevent
CFLAGS=-m64 LDFLAGS=-m64 ./configure
make
sudo make install

安装memcached
CFLAGS=-m64 LDFLAGS=-m64 ./configure --prefix=/usr/local/memcached
make
sudo make install

启动memcached
/usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root
遭遇：
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory

通过LD_DEBUG=libs /usr/local/memcached/bin/memcached -h
看到类似输出

30596: trying file=/usr/lib64/libevent-1.4.so.2

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
可以看到是在加载/usr/lib64/libevent-1.4.so.2文件时出现了问题，系统中确实是没有该文件的，查找后发现libevent-1.4.so.2存在于/usr/local/lib目录
然后做个软链接
ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib64/libevent-1.4.so.2

然后再来：
/usr/local/memcached/bin/memcached -d -m 1024 -p 11211 -u root

ps -A | grep memcached
可以看到
12389 ? 00:00:00 memcached
表明OK

那么，如何让它在系统启动的时候自启动呢：
达人告诉我：
在/etc/rc.d/rc.local中加入一行，上面命令
try it
