QConf 管理端接口（PHP）

使用

• 安装QConf管理端的c++库

进入manager目录，通过以下命令构建:

mkdir build && cd build
cmake ..
make
make install

默认的安装目录为 /usr/local/qconf/manage

使用如下配置可以指定安装目录:

cmake .. -DCMAKE_INSTALL_PREFIX=/install/prefix

• 编译并安装qconf manager的php扩展

phpize
./configure 
  --with-php-config=${php-config 命令} 
  --with-qconfzk-dir=${qconf 安装目录}/manage/include 
  --enable-static 
  LDFLAGS=${qconf 安装目录}/manage/lib/libqconf_zk.a
make
make install

接口说明

构造函数

QConfZK($zoo_host);

Parameters

zoo_host - Zookeeper location，comma separated host:port pairs, each corresponding to a zk server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002"

Example

配置相关函数

nodeGet($path)
nodeSet($path, $value)
nodeDelete($path)

Parameters

path - key of configuration.

value - value of the new configuration

Return Value

nodeGet return value of the configuation, NULL if failed

nodeDelete and node Set return 0 if success, othres if failed

  $qzk = new QConfZK("127.0.0.1:2181");
  $qzk->nodeSet("/demo/config", "value");
  $value = $qzk->nodeGet("/demo/config");
  echo $value . PHP_EOL;
  $qzk->nodeDelete("/demo/config");

service - service ip:port

status - the services status, can be one of QCONF_STATUS_UP, QCONF_STATUS_DOWN, QCONF_STATUS_OFFLINE

array_services - new service array of ip:port and status pair

Return Value

servicesGet return array of service ip:port, NULL if failed

servicesGetWithStatus return array of service ip:port and status pair

other function return 0 if success

Example

  <?php
  $qzk = new QConfZK("127.0.0.1:2181");

  $service_path = "/demo/services";
  $services_input = array("1.1.1.1:80" => QCONF_STATUS_UP, "1.1.1.2:80" => QCONF_STATUS_DOWN);

  $qzk->servicesSet($service_path, $services_input);
  $services_output = $qzk->servicesGetWithStatus($service_path);
  $services_output_k = $qzk->servicesGet($service_path);
  var_dump($services_output);
  var_dump($services_output_k);

  $qzk->serviceAdd($service_path, "1.1.1.3:80", QCONF_STATUS_UP);
  $qzk->serviceOffline($service_path, "1.1.1.3:80");
  $qzk->serviceDown($service_path, "1.1.1.3:80");
  $qzk->serviceUp($service_path, "1.1.1.3:80");
  $qzk->serviceDelete($service_path, "1.1.1.1:3:80");
  $qzk->serviceClear($service_path);
  ?>

子配置相关函数

list($path)
listWithValue($path)

Parameters

path - key of configuration.

Return Value

list return array of all children config key, NULL if failed

listWithValue return array of all children config key together its value, NULL if failed

Example

  $qzk = new QConfZK("127.0.0.1:2181");
  var_dump($qzk->list("/demo"));
  var_dump($qzk->listWithValue("/demo"));

灰度功能相关

grayBegin($array_key, $array_machine)
grayRollback($gray_id)
grayCommit($gray_id)

Parameters

array_key - array of all key value pair, which need to be in gray process

array_machine - array of gray machine hostname

gray_id - return value of grayBegin

Return Value

grayBegin return gray_id, the unique id of current gray process

grayRollback and grayCommit 0 if success

Example

  $machines = array($hostname);
  $nodes = array("/demo/gray1" => "value1", "/demo/gray2" => "value2");
  $gray_id = $qzk->grayBegin($nodes, $machines);

  assert(0 === $qzk->grayCommit($gray_id));
  //assert(0 === $qzk->grayRollback($gray_id));
