安装
php-zookeeper扩展需要依赖libzookeeper，翻阅zookeeper官方文档 传送门 ，我们下载对应zookeeper集群版本一致的软件包，进行解压缩，利用源码中c语言版本源码进行lib安装
cd [zookeeper tarball dir]/src/c
./configure
make && make install
安装后可以在/usr/local/include/zookeeper中找到对应的header文件
下面继续php-zookeeper扩展的安装
cd [php-zookeeper-master]
phpize
./configure --with-php-config=[php-config-dir] --with-libzookeeper-dir=/usr/local
注意上面的libzookeeper-dir的填写，只要写/usr/local即可，config会自动寻找这个目录下的include/zookeeper目录
if test -r "$PHP_LIBZOOKEEPER_DIR/include/c-client-src/zookeeper.h"; then
PHP_LIBZOOKEEPER_DIR="$PHP_LIBZOOKEEPER_DIR"
elif test -r "$PHP_LIBZOOKEEPER_DIR/include/zookeeper/ zookeeper.h"; then
PHP_LIBZOOKEEPER_DIR="$PHP_LIBZOOKEEPER_DIR"
elif test -r "$PHP_LIBZOOKEEPER_DIR/include/zookeeper.h"; then
PHP_LIBZOOKEEPER_DIR="$PHP_LIBZOOKEEPER_DIR"
else
AC_MSG_ERROR([Can't find zookeeper headers under "$PHP_LIBZOOKEEPER_DIR"])
fi
继续扩展安装，conigure完毕后
make && make install
修改php.ini将扩展加入进来
[zookeeper]
extension=zookeeper.so
