PHP-Zookeeper扩展安装

问题

• 使用pecl安装扩展
  在编译extension时候会 ZOO_MAJOR_VERSION 错误，由于pecl的源码包没有修复bug，建议使用GitHub下载
• 网上很多文章教程基于zookeeper3.5.9之前，zookeeper软件目录及文件已经变化,新版不存在/src/c 这个目录

环境准备

zookeeper 版本：Apache ZooKeeper, version 3.6.2
php版本：PHP 7.3.27 (cli) (built: Apr 20 2021 13:59:37) ( NTS )
extension：php- zookeeper 0.7.2
linux：centos 8

系统环境

yum install -y cppunit-devel antl gcc build-essential zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc-c++ autoconf automake

Zookeeper C Binding

参考：https://github.com/php-zookeeper/php-zookeeper

低于ZooKeeper 3.5.9

# 在 apache-zookeeper-3.5.9/src/c 下执行
$ ./configure --prefix=/usr/local/zookeeper-lib
$ make
$ sudo make install

ZooKeeper 3.5.9

$ autoreconf -if
$ ant compile_jute
$ ./configure --prefix=/usr/local/zookeeper-lib
$ make
$ sudo make install

ZooKeeper 3.6.x之后

$ autoreconf -if
# 从ZooKeeper 3.6.0开始，由于缺少build.xml，ant将失败。该文件和另外两个文件可以在3.5.9的源压缩包中找到
$ cd apache-zookeeper-3.5.9
$ cp build.xml ivy* ../apache-zookeeper-3.6.x
# 在 apache-zookeeper-3.6.x 根目录执行
$ ant compile_jute
# 在 zookeeper-client/zookeeper-client-c 下执行
$ ./configure --prefix=/usr/local/zookeeper-lib
$ make
$ sudo make install

安装PHP扩展

下载

$ git clone https://github.com/php-zookeeper/php-zookeeper.git

安装

不要使用 pecl 有bug

# 在php-zookeeper目录下执行
[root@localhost php-zookeeper]#  phpize
[root@localhost php-zookeeper]#  ./configure --with-libzookeeper-dir=/usr/local/zookeeper-lib
[root@localhost php-zookeeper]#  make

----------------------------------------------------------------------
Libraries have been installed in:
   /root/php-zookeeper/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     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.
----------------------------------------------------------------------
[root@localhost php-zookeeper]# make install
Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/

配置

将 /usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/zookeeper.so 加入到php.ini

验证

# 重启服务
$ service php-fpm restart
$ service nginx restart
[root@localhost zookeeper-client-c]# php -i | grep zookeeper
