This article is about how to install the zookeeper extension in php. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Installation method: 1. Install and start zookeeper server;2. Download zookeeper extension and extract it to ext directory of PHP installation directory;3. Under php installation directory, execute command to generate configure and makefile;4. Use make command to compile and install.

This tutorial operating environment: centos 6.4 system, PHP 5.5.10 version, DELL G3 computer

ZooKeeper is a distributed, open source distributed application coordination service, an open source implementation of Google Chubby, and an important component of Hadoop and Hbase. It is a software that provides consistency services for distributed applications, including configuration maintenance, domain name services, distributed synchronization, group services, etc.

ZooKeeper's goal is to encapsulate complex and error-prone critical services, providing users with easy-to-use interfaces and efficient, stable systems.

To use zookeeper in php, install the php zookeeper extension. To install the php zookeeper extension, install zookeeper.

How to install php zookeeper extension

Environment:

centos : 6.4

zookeeper : 3.4.5

php : 5.5.10

nginx : 1.5

php zookeeper extension:0.2.2

If nginx is not installed, install nginx first; make sure nginx is configured first, and then proceed

If php is not installed, install php first (after configuring php support for nginx, install zookeeper extensions)

Install Zookeeper

download

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz

Unzip (whatever directory you put it in, just remember)

tar zxfv zookeeper-3.4.5.tar.gz

Start zookeeper server

cd zookeeper-3.4.5/confcp zoo_sample.cfg zoo.cfgcd ../ bin./ zkServer.sh start Here it is best to confirm whether you expect success,./ zkServer.sh status

I'm single here, so the result is:

[root@localhost bin]# ./ zkServer.sh statusJMX enabled by defaultUsing config: /root/zookeeper-3.4.5/bin/../ conf/zoo.cfgMode: standalone Compile zookeeper library for php

cd ../ src/c./ configure --prefix=/usr/local/zookeeperlibmake && make install

Install PHP Zookeeper Extension

download

wget http://pecl.php.net/get/zookeeper-0.2.2.tgz

Unzip (unzip the package.xml and don't bother with it)

tar zxvf zookeeper-0.2.2.tgz

Put it in/root/php-5.5.10/ext

mv zookeeper-0.2.2 /root/php-5.5.10/ext/cd /root/php-5.5.10/ext/

Change directory name

mv zookeeper-0.2.2 zookeeper

Back to php-5.5.10 directory

cd .../ buildconf --force./ configure -h|grep zookeeper

Check if configure already supports zookeeper

--enable-zookeeper Enable zookeeper support--disable-zookeeper-session Disable zookeeper session handler support--with-libzookeeper-dir=DIR Set the path to libzookeeper install prefix.

If the above is displayed, it means that it has been supported. Continue to the next step.

cd ext/zookeeper

Generating configuration

/usr/local/php5.5.10/bin/phpize

Generate makefile

./ configure --with-php-config=/usr/local/php5.5.10/bin/php-config --with-libzookeeper-dir=/usr/local/zookeeper Note the path above:--with-php-config is the path to php installation--with-libzookeeper-dir is the path to install zookeeper library in step 1 compile installation

make && make install

The result is, the next configuration of this result is going to use

Installing shared extensions: /usr/local/php5.5.10/lib/php/extensions/no-debug-non-zts-20121212/

Add ext path and file name

vim /usr/local/php5.5.10/etc/php.ini extension_dir="/usr/local/php5.5.10/lib/php/extensions/no-debug-non-zts-20121212/"extension=zookeeper.so

recompile php

Enter the Php source folder, do not enter the wrong. My source folder is/root/php-5.5.10 and the installation directory is/usr/local/php 5.5.10

cd /root/php-5.5.10rm -rf autom4te.cache/ configure./ buildconf --force./ configure -h|grep zookeeper

Check if configure already supports zookeeper

If it's supported, move on.

./ configure --prefix=/usr/local/php5.5.10 --with-config-file-path=/usr/local/php5.5.10/etc --with-bz2 --with-curl --enable-ftp --enable-sockets --disable-ipv6 --with-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-freetype-dir=/usr/local --enable-gd-native-ttf --with-iconv-dir=/usr/local --enable-mbstring --enable-calendar --with-gettext --with-libxml-dir=/usr/local --with-zlib --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-mysql=mysqlnd --enable-dom --enable-xml --enable-fpm --with-libdir=lib64 --enable-zookeeper --with-libzookeeper-dir=/usr/local/zookeeperlib --enable-sockets make && make install

Here, the support has been installed, to test whether it is normal

In zookeeper-0.2.2.tgz (that is, zookeeper extension of Php), there is an examples/Zookeeper_Example.php file that can be used to test

cp /root/php-5.5.10/ext/zookeeper/examples/Zookeeper_Example.php /usr/local/nginx/html//usr/local/php5.5.10/bin/php /usr/local/nginx/html/Zookeeper_Example.php

See if you can print the following results

string(0) ""array(1) { [0]=> string(9) "zookeeper"}NULLstring(3) "abc"array(2) { [0]=> string(7) "test123" [1]=> string(9) "zookeeper"}NULLNULLarray(2) { [0]=> string(3) "001" [1]=> string(3) "002"}

Restart php-fpm

killall php-fpm/usr/local/php5.5.10/sbin/php-fpm

You can now access php that supports zookeeper extensions through your browser

If you have any other questions, please check:

1、iptables

2、selinux
