Install zookeeper extension in linux php

Preface:

Zookeeper provides sharp naming services and cluster operations are atomic. Therefore, it is used in multiple projects.

In the original project, the status of the server cluster is uniformly reported to the zookeeper cluster, and then the zookeeper is accessed through the client to observe the status of the cluster in real time (of course, you can also configure synchronization ). However, the cross-platform client is not convenient. It is too egg pain to develop a mobile client. Therefore, we plan to use PHP to read zookeeper.

Environment:

1 2 3 4 5

centos : 6.4 zookeeper : 3.4.5 php : 5.5.10 nginx : 1.5 Php zookeeper extension:0.2.2

1. If nginx is not installed, install nginx first, you can refer to: http://hi.baidu.com/solohac/item/081e97e54868403f86d9deff

Make sure that nginx is configured first, and then proceed to the next step.

2. If php is not installed, install php first (configure nginx php support before installing zookeeper extension)

Download

Wget http://hk2.php.net/distributions/php-5.5.10.tar.gz

Extract

Tar zxvf php-5.5.10.tar.gz

Generation and Installation

Cd php-5.5.10

1

./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

Make & make install

Configure php

1 2	cp php.ini-production /usr/local/php5.5.10/etc/php.ini cp /usr/local/php5.5.10/etc/php-fpm.conf.default /usr/local/php5.5.10/etc/php-fpm.conf

Start

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

Check whether the port is listening

Netstat-lnt | grep 9000

Edit nginx configuration file

1 2 3 4 5 6 7 8 9 10 11

location ~ .*\.(php)?$ { expires -1s; try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:9000; }

Nginx reload Configuration

Nginx-s reload

Test php access

Cd/usr/local/nginx/html/

Vim aa. php

Write content

1 2 3

echo "test php"; ?>

If php can be accessed normally, continue with the following installation. If not, check the php support.

2. Install zookeeper

Download

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

Decompress the package (whatever directory you want, just remember)

Tar zxfv zookeeper-3.4.5.tar.gz.

Start the zookeeper Server

1 2 3 4

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

It is best to confirm whether the request is expected to be successful,./zkServer. sh status

The result is as follows:

1 2 3 4

[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

1 2 3

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

3. Install zookeeper extension of php

Download

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

Decompress the package. xml file)

Tar zxvf zookeeper-0.2.2.tgz

Put him in/root/php-5.5.10/ext

Mv zookeeper-0.2.2/root/php-5.5.10/ext/

CDS/root/php-5.5.10/ext/

Change directory name

Music zookeeper-0.2.2 zookeeper

Back to php-5.5.10 directory

Cd ..

./Buildconf -- force

./Configure-h | grep zookeeper

Check whether configure supports zookeeper.

1 2 3

--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 shown above, it indicates it is supported. continue to the next step.

Cd ext/zookeeper

Generate configure

/Usr/local/php5.5.10/bin/phpize

Generate makefile

1 2 3 4

./configure --with-php-config=/usr/local/php5.5.10/bin/php-config --with-libzookeeper-dir=/usr/local/zookeeperlib Note the preceding path: --with-Php-config is the php installation path. --with-Libzookeeper-dir is the path for installing the zookeeper library in step 1.

Compile and install

Make & make install

The result is as follows:

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

Add ext path and file name

1 2 3 4

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

4. recompile php

Go to the Php source code folder and do not enter an error. My source code folder is/root/php-5.5.10, 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 whether configure supports zookeeper.

If yes, continue.

. /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

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

There are examples/Zookeeper_Example.php files in the zookeeper-0.2.2.tgz (that is, the zookeeper extension of Php) that can be used to test

1 2	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

Check whether the following results can be printed.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

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" }

Restart php-fpm

Killall php-fpm

/Usr/local/php5.5.10/sbin/php-fpm

Now you can access php that supports zookeeper extension through a browser.
