How to install the 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 to configure nginx first before proceeding

If php is not installed, install php first (first configure nginx’s php support, and then install the zookeeper extension)

Install zookeeper

Download

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

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

tar zxfv zookeeper-3.4.5.tar.gz

Start the zookeeper server

cd zookeeper-3.4.5/conf
cp zoo_sample.cfg zoo.cfg
cd ../bin
./zkServer.sh start

The most important thing here To confirm whether you expect success, ./zkServer.sh status

I have a single server here, so the result is:

[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /root/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: standalone

Compile the zookeeper library for PHP

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

Install the zookeeper extension for php

##Download

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

Unzip(Don’t worry about the unzipped package.xml)

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

Go back to the php-5.5.10 directory

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

Check whether 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 it is displayed as above, The description is already supported, continue below

cd ext/zookeeper

Generate configure

/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/zookeeperlib
注意上面的路径:
--with-php-config是php安装的路径
--with-libzookeeper-dir是第一步中install zookeeper库的路径

Compile and install

make && make install

The result is, the next configuration of this result will be used

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

Add the 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 source code folder of Php, don’t enter it by mistake. My source code folder is /root/php-5.5.10, and the installation directory is /usr/local/php5.5.10

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

Check if configure already supports zookeeper

If it already supports it , continue down

./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, let’s test whether it is normal

In zookeeper-0.2.2.tgz (that is, the zookeeper extension of Php), there is examples/Zookeeper_Example.php file 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

to see if the following results can be printed

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