Memcached未显示在phpinfo（）中

我已经安装了libmemcached和memcached-pecl-extension-for-php，但由于某些原因，它没有正确安装？我已经在/usr/lib64/php/中使用了memcached.so，并在/usr/local/lib中使用了libmemcache.so/

一切似乎都正确无误地构建，我重新启动了apache

我还安装了守护进程

我以前很容易地为php安装了Memcache类，但是我意识到我想要的是Memcached（注意d）类。如果需要更多信息，请告诉我

编辑：我以前让memcache（没有d）在php中工作，所以我知道我在操作正确的php.ini

编辑2：确实有一个apache错误

Unable to load dynamic library '/usr/lib64/php/modules/memcached.so' - /usr/lib64/php/modules/memcached.so: undefined symbol: php_json_encode in Unknown on line 0

我已经在centos5中使用yum安装程序而不是pecl安装memcached解决了这个问题

这样-->yum安装php-pecl-memcached

---

然后，服务httpd重新启动，它显示在phpinfo（）中。

几天前我遇到了类似的错误。安装memcached的新版本（2.0）对我有帮助

yum -y install gcc-c++
wget http://launchpad.net/libmemcached/1.0/0.50/+download/libmemcached-0.50.tar.gz
tar xzf libmemcached-0.50.tar.gz 
cd libmemcached-0.50
./configure 
make 
make install
wget http://pecl.php.net/get/memcached-2.0.0b2.tgz
pecl install memcached-2.0.0b2.tgz
echo 'extension=memcached.so' > /etc/php.d/memcached.ini
service php-fpm restart
cd ..
rm -r libmemcached-0.50*
rm -r memcached-

在php.ini中，然后重新启动apache

我不知道这是否是同一个问题，但经过几个小时的努力，我使用下面的命令在CentOS上正确安装了带有Memcached的php：

yum --enablerepo=remi-php73 install php-memcached

测试安装：

php -i | grep -i memcache

应该显示如下内容：

/etc/php.d/50-memcached.ini

您能否验证apache错误日志中没有错误？您是否将

扩展名=memcache.so

添加到正确的php.ini中？是的，有错误。如何修复显示的错误？只需在memcached之前修复扩展加载顺序json。（使用分发包，每个扩展都有一个以数字开头的配置文件，以确保正确的加载顺序）hm，没有想到这一点。下次我就试试这个！
