php7 安装 memcached ，memcache扩展

memcached 之前安装过一次，后来一次断电，虚拟机挂的那个彻底，之前装的那次只是很简单的记录了一下，最近有个好玩的小东西用到了memcache，没办法重新装memcache 遇到一堆一堆的坑，记录下，也供大家参考~

环境 :centeos 6.5 php7.0.2 memcached 1.5.1 扩展 memcached3.0.0

https://pecl.php.net/package/memcached
可以查看memcached 对应版本所需 libevent包版本

查看libevent包版本
rpm -qa|grep libevent 我的提示没有这个包，如果版本不够则卸载重新安装
卸载：rpm -e libevent-1.4.13-4.el6.x86_64

重新安装 libevent
wget https://github.com/libevent/libevent/archive/release-2.1.8-stable.tar.gz tar -zxvf libevent-2.0.21-stable.tar.gz
安装
./configure --prefix=/usr/local/libevent  (指定安装到/usr/local/libevent目录下)
编译：make

make install

下载最新版memcached wget http://memcached.org/latest 解压 tar -zxvf latest
当前目录 pwd /usb/src/
进入目录 cd memcached-1.5.1/ (这个目录在安装php扩展的时候需要用到 memcahced.h　这个文件)
解压 tar-zxvf
memcached-1.x.x.tar.gz
生成配置文件 ./configure --with-libevent=/usr/local/libevent/ --prefix=/usr/local/memcached

我之后才装的libevent，报了这个错，解决办法参照上面libevent安装

报这个错：需要安装 libevent
checking for libevent directory... configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/ If it's already installed, specify its path using --with-libevent=/dir/

最后

make && make install

最后

安装成功

启动memcached

/usr/local/memcached/bin/memcached -d -m 128 -u root -p 11211 -c 1024 -P /tmp/memcached.pid

ps -ef|grep memcached

root 787 0.0 0.0 0 0 ? S 20:07 0:00 [vmmemctl]
root 21079 0.0 0.1 442284 3660 ? Ssl 21:17 0:00 /usr/local/memcached/bin/memcached -d -m 128 -u root -p 11211 -c 1024 -P /tmp/memcached.pid
root 21761 0.0 0.0 103328 860 pts/1 S+ 21:30 0:00 grep mem

安装PHP-memcached

git clone https://github.com/php-memcached-dev/php-memcached.git
cd php-memcached/

git checkout php7

执行 /usr/local/php7/bin/phpize

执行 ./configure

报错：
checking for memcached msgpack support... disabled
checking for libmemcached location... configure: error: Unable to find memcached.h under /usb/src/memcached-1.5.1/

这里卡了好久...

百度：
执行：
sudo mkdir -p /usr/lib/x86_64-linux-gnu/include/libmemcached

sudo ln -s/usb/src/memcached-1.5.1/memcached.h
/usr/lib/x86_64-linux-gnu/include/libmemcached/memcached.h

然后重新执行
./configure --with-php-config=/usr/local/php7/bin/php-config --enable-memcached --with-libmemcached-dir=/usr/lib/x86_64-linux-gnu --disable-memcached-sasl

creating libtool
appending configuration tag "CXX" to libtool
configure: creating ./config.status
config.status: creating config.h
config.status: config.h is unchanged

make && make install

during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.

cd /usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012

此时发现 多了第一个 memcached.so 的扩展

重启php。

service php-fpm restart

在php.ini 中加入 memcache扩展
extension=memcached.so;

测试文件中 phpini(); 查找 memcached

memcached

memcached support	enabled
Version	3.0.0b1
libmemcached version	1.0.18
SASL support	no
Session support	yes

搞定~！
