mac 安装memcached.so扩展

一：下载源码包

http://pecl.php.net/package/memcached     （PHP5.6选择2.2.0版本，PHP7选择3.X版本）

 

二：解压下载的文件 

tar zxvf memcached-3.1.3.tar

 

三：执行命令

1：cd memcached-3.1.3

2：phpize        //执行phpize命令生成configure建立php外挂模块

3：./configure --prefix=/usr/local/Cellar/php\@7.1/7.1.19/bin/php-config      //根据自己的php-config地址

4：make && make install（mac会报错，除非你的mac OSX 系统版本低）

报错信息：

Installing shared extensions: /usr/lib/php/extensions/no-debug-non-zts-20160303/

cp: /usr/lib/php/extensions/no-debug-non-zts-20160303/#INST@49327#: Operation not permitted     即使sudo make && make install也一样会报错

 

错误原因：

因为是OSX 10.11 El Capitan开始，新添加了一个新的安全机制叫系统完整性保护System Integrity Protection (SIP)，所以对于目录
/System，/sbin，/usr （不包含/usr/local/）仅仅供系统使用，其它用户或者程序无法直接使用，而我们的/usr/lib/php/extensions/刚好在受保护范围内。

 

解决办法是，禁掉SIP保护机制:

1. 重启系统
2. 按住Command + R   （重新亮屏之后就开始按，象征地按几秒再松开，出现苹果标志，ok）
3. 菜单“实用工具” ==>> “终端” ==>> 输入csrutil disable；执行后会输出：Successfully disabled System Integrity Protection. Please restart the machine for the changes to take effect.
4. 重启系统

禁止掉SIP后，就可以顺利的安装了，当然装完了以后记得重新打开SIP，方法同上，只是命令是csrutil enable。

 

以上解决方法可以不用，直接用该步骤也可以完成安装：

      源码文包文件里面的model已经有对应memcached.so文件(若没有，make && make install编译后在看下)，仔细看编译过程会有这个命令：cp ./.libs/memcached.so /Users/leyangjun/Downloads/memcached-3.1.3/modules/memcached.so 相关的拷贝动作

      把memcached.so文件直接拷贝到你的扩展目录下面就行

leyangjundeMacBook-Pro:20160303 leyangjun$ cp /Users/leyangjun/Downloads/memcached-3.1.3/modules/memcached.so ./   leyangjundeMacBook-Pro:20160303 leyangjun$ pwd /usr/local/Cellar/php@7.1/7.1.19/pecl/20160303 leyangjundeMacBook-Pro:20160303 leyangjun$ ll total 1304 -rwxr-xr-x  1 leyangjun  admin   71332  8  9  2018 memcache.so -rwxr-xr-x  1 leyangjun  admin  115416  3 29 13:46 memcached.so -rwxr-xr-x  1 root       admin  471948  8  9  2018 redis.so   查看自己的扩展目录地址在php.ini文件中就可以查看 (vi php.ini) extension_dir=/usr/local/Cellar/php@7.1/7.1.19/pecl/20160303/   --这就是分区目录 extension=memcached.so   --在此增加对应扩展名   重启PHP： sudo pkill -9 php-fpm sudo /usr/local/Cellar/php\@7.1/7.1.19/sbin/php-fpm -D

 

增加完配置后，重启PHP即可
