携程Apollo的PHP客户端
php version >= 7.0
$ composer require multilinguals/apollo-client
php version >= 5.4 , <7.0
$ composer require multilinguals/apollo-client --ignore-platform-reqs
- 支持apollo配置变更的实时获取
- 支持拉取配置后自定义的回调处理
客户端以cli的方式后台启动执行,支持apollo配置的适时获取,并将配置保存在指定的目录供应用程序读取解析
#!/usr/bin/env php
<?php
require 'vender/autoload.php'; // autoload
use Org\Multilinguals\Apollo\Client\ApolloClient;
//specify address of apollo server
$server = getenv('CONFIG_SERVER'); // get server address from env
//specify your appid at apollo config server
$appid = getenv('APPID'); // get appid from env
//specify namespaces of appid at apollo config server
$namespaces = getenv('NAMESPACE'); // get namespaces from env
$namespaces = explode(',', $namespaces);
$apollo = new ApolloClient($server, $appid, $namespaces);
if ($clientIp = getenv('CLIENTIP')) {
$apollo->setClientIp($clientIp);
}
ini_set('memory_limit','128M');
$pid = getmypid();
echo "start [$pid]\n";
$restart = true; //auto start if failed
do {
$error = $apollo->start();
if ($error) echo('error:'.$error."\n");
}while($error && $restart);
拉取的配置默认保存在脚本所在目录,每个namespace的配置以apolloConfig.{$namespaceName}.php
的方式命名保存
在docker的启动脚本中加入启动代码,一般的php容器启动脚本是docker-php-entrypoint
if [ -f "/path/to/start.php" ]; then
apollo_ps=$(ps -aux | grep -c "php /path/to/start.php")
if [ $apollo_ps -eq 1 ]; then
php /path/to/start.php &
