在 Swoole 文档中有这么一说明
" 平滑重启只对onWorkerStart或onReceive等在Worker进程中include/require的PHP文件有效，Server启动前就已经include/require的PHP文件，不能通过平滑重启重新加载 "
让我们来测试一下:
# php http_server.php
WorkerStart
WorkerStart
访问 https://www.test-yy.com
页面内容输出 " hello Swoole test "
命令行中输出:
Test1
request 100Test1
当我们将
test.php
test_request.php
代码中的 Test1 替换成 Test2 时
访问 https://www.test-yy.com
命令行中输出:
Test1
request 88Test2
# ps -ef | grep php
# kill -USR1 8155 // 平滑重启，8155（主进程/管理进程 id）
再次访问 https://www.test-yy.com
命令行中输出:
Test1
request 88Test2
以上结果说明了 include/require ，再 Server 启动前载入的PHP文件，不能通过平滑重启重新加载
测试代码:
http_server.php
<?php
echo 'shell start';
define('__ROOT__', realpath('.'));
include __ROOT__.'/test.php';
$http = new swoole_http_server("127.0.0.1", 9501);
$http->set([
'worker_num'=>2,
'max_request'=>50
]);
$http->on('WorkerStart', function ($serv, $worker_id){
echo "WorkerStart \n";
});
$http->on('request', function ($request, $response) {
getTest();
include __ROOT__.'/test_request.php';
$response->header("Content-Type", "text/html; charset=utf-8");
$response->end(getTplContent());
});
$http->start();
function getTplContent() {
return "hello Swoole test \n";
}
?>
test.php
<?php
function getTest() {
echo "Test1 \n";
}
?>
test_request.php
<?php
echo 'request '.rand(1,100)."Test1 \n";
?>
nginx 配置
test.conf
server {
listen 80;
server_name www.test-yy.com;
...
location ~\.php$ {
proxy_http_version 1.1;
proxy_set_header Connection "keep-alive";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass https://127.0.0.1:9501;
}
}
