CentOS(x86_64)下PHP安装memcache扩展问题解决办法分享

人气:0
系统版本是5.2,把安装memcached的方法记录下先:


cd ~/memcached
wget -c http://www.monkey.org/~provos/libevent-1.4.10-stable.tar.gz
wget -c http://memcached.googlecode.com/files/memcached-1.2.8.tar.gz
#安装libevent
tar -zxvf libevent-1.4.10-stable.tar.gz
cd libevent-1.4.10-stable
./configure
make
make install
#安装memcached
cd ..
tar -zxvf memcached-1.2.8.tar.gz
cd memcached-1.2.8
./configure
make
make install
#如果是64位系统,还需要把libevent的文件复制到/wp-content/lib64/下,用来解决error while loading shared libraries的问题
cp -R /wp-content/local/lib/libevent* /wp-content/lib64/


好了,开始安装php的扩展,恶梦开始了,本以为直接用yum来安装php-devel.x86_64和php-pecl-memcache.x86_64这两个扩展就可以了,可装了后 phpinfo()里根本找不到memcache扩展,把已经装的这两个扩展remove重来,还是不行,goooooooooooooogle,找到了一篇文章《PHP Pecl Memcached module installation problems》,有救喽,先remove掉php-pecl-memcache.x86_64,然后执行了

pecl install memcache

顺利安装上了,打开/etc/php.d/看了下,没有memcache.ini,好吧,手动到/etc/php.ini加上了 extension=memcache.so,好了,重启httpd,刷新 phpinfo() ,竟然还没有,我郁闷了。。

回头想想,我好像漏了一个地方没有检查,马上打开 /wp-content/lib64/php/modules/ 查看,果然没有memcache.so,会在哪呢? find -name之,原来躲在 /wp-content/local/lib/php/extensions/no-debug-non-zts-20060613/ 下,复制到 /wp-content/lib64/php/modules/ 再试,久违的 memcache扩展出现了。 T T
