背景:在CenOS7.7下
1 编译、安装、测试
# 安装依赖包 yum -y install cyrus-sasl-devel # 编译安装libmemcached tar -zxvf libmemcached-1.0.18.tar.gz cd libmemcached-1.0.18 ./configure && make && make install && cd .. # 为PHP的Memcached扩展生成configure文件 tar -zxvf memcached-2.2.0.tgz (我实际使用了 memcached-3.1.5版本) cd memcached-2.2.0 /usr/local/php/bin/phpize # 编译安装PHP的Memcached扩展 ./configure --with-php-config=/usr/local/php/bin/php-config make && make install && cd .. # 在PHP的配置文件php.ini中加载Memcached扩展 vi /usr/local/php/lib/php.ini # 添加如下配置 extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/memcached.so # PHP-FPM重新加载配置 service php-fpm reload # 测试Memcached vi /data/www/test.php <?php # 连接Memcached服务器 $mem = new Memcached(); $mem->addServer('192.168.78.19', 11211); # 保存数据(Key/Value形式,Key=UserName,Value=James) $mem->set('UserName', 'James'); # 获取数据(根据Key=UserName,获得Value)输出结果:James echo $mem->get('UserName'); ?>
2 出现的问题
2.1 编译libmemcached(./configure)时报错
报错内容如下:
clients/memflush.cc:42:22: error: ISO C++ forbids comparison between pointer and integer [-fpermissive] if (opt_servers == false) ^~~~~ clients/memflush.cc:51:24: error: ISO C++ forbids comparison between pointer and integer [-fpermissive] if (opt_servers == false) ^~~~~
原因:gcc版本比较高,不兼容。
解决方法:对源码略作修改。
# 将clients/memflush.cc的42行和51行作如下修改: int main(int argc, char *argv[]) { options_parse(argc, argv); - if (opt_servers == false) + if (!opt_servers) { char *temp; - if (opt_servers == false) + if (!opt_servers) { std::cerr << "No Servers provided" << std::endl; exit(EXIT_FAILURE);
然后再次make,编译通过。
2.2 编译memcached-3.1.5报错
报错内容如下:
configure: error: no, libmemcached built with sasl disabled. Run configure with --disable-memcached-sasl or update libmemcached with sasl support
添加--disable-memcached-sasl,再次编译通过:
./configure --with-php-config=/usr/local/php/bin/php-config --disable-memcached-sasl
