六、Swoole 基础学习笔记 - 深入学习 Tcp Server 运行时参数配置
hi，我是温新，一名PHPer
文章基于 Swoole 5.0 版本编写。
学习目标：记住 Swoole Tcp 常用配置，了解其他相关配置
说明：本篇文章结合官方文档编写及参考网络资料编写，虽非全部原创，但也是结合了自己的理解，若转载请附带本文 URL，编写不易，持续编写更不易，谢谢！
上篇文章正式对是 Tcp Server 进行了一个记录，本篇文章将学习相关参数的配置。本篇文章将学习常用参数的配置，没有记录的参数请参考官方文档。
set 配置
max_conn
作用：服务器程序，最大允许的连接数（默认值为： ulimit -n）。
如：max_conn => 1000 ，设置 Server 最大允许维持 1000 个 TCP 连接。超过此数量后，新进入的连接将被拒绝。
max_conn 不允许设置太小，最设置的最小值为： (worker_num + task_worker_num) * 2 + 32
max_request
作用：设置 worker 进程的最大任务数。【默认值：0 即不会退出进程】。一个 worker 进程在处理完超过此数值的任务后将自动退出，进程退出后会释放所有内存和资源。
注意：此选项可以用于防止 worker 进程内存溢出。

配置好之后，使用另外一个客服端连接服务器，连接成功后向服务端发送数据，然后看看进程的变化：

task_worker_num
作用：配置 Task 进程数量。
注意：配置 task_worker_num 参数后，务必在 Server 中注册 onTask、onFinish 事件回调。若没有注册，服务器程序将无法启动。
提示：
- Task进程是同步阻塞的；
- 最大值不得超过 swoole_cpu_num() * 1000；
- 计算方法
- 单个
task的处理耗时，如100ms，那一个进程 1 秒就可以处理1/0.1=10个 task； -
task投递的速度，如每秒产生2000个task； -
2000/10=200，需要设置task_worker_num => 200，启用200个 Task 进程。

daemonize
作用：守护进程化【默认值：false】。设置 daemonize => true 时，程序将转入后台作为守护进程运行。长时间运行的服务器端程序必须启用此项。如果不启用守护进程，当 ssh 终端退出后，程序将被终止运行。
提示：
- 启用守护进程后，标准输入和输出会被重定向到
log_file； - 如果未设置
log_file，将重定向到/dev/null，所有打印屏幕的信息都会被丢弃； - 启用守护进程后，
CWD（当前目录）环境变量的值会发生变更，相对路径的文件读写会出错。PHP程序中必须使用绝对路径。

方法
on
作用：用于注册 Server 的事件回调函数。
在之前的文章中见到它的次数很多了，监听某个事件回调就用它。要注意的是，重复调用同一个事件时，新的覆盖旧的，如下案例：

start
作用：启动服务器，监听所有 TCP/UDP 端口。
reload
作用：安全地重启所有 Worker/Task 进程。
stop
作用：使当前 Worker 进程停止运行，并立即触发 onWorkerStop 回调函数。
shutdown
作用：关闭服务。
close
作用：关闭客户端连接。
send
作用：向客户端发送数据。
sendfile
发送文件到 TCP 客户端连接。
sendto
作用：向任意的客户端 IP:PORT 发送 UDP 数据包。
sendMessage
作用：向任意 worker 进程或 task 进程发送消息。在非主进程和管理进程中可调用。收到消息的进程会触发 onPipeMessage 事件。
exists
作用：检测 fd 对应的连接是否存在。
getClientInfo
作用：获取连接的客户端信息。
getClientList
作用：遍历当前 Server 所有的客户端连接，Server::getClientList 方法是基于共享内存的，不存在 IOWait，遍历的速度很快。另外 getClientList 会返回所有 TCP 连接，而不仅仅是当前 Worker 进程的 TCP 连接。别名是 Swoole\Server->connection_list()。
getWorkerId
作用：获取当前 Worker 进程 id（非进程的 PID）。
getWorkerPid
作用：获取当前 Worker 进程 PID。
getWorkerStatus
作用：获取 Worker 进程状态。

事件
onStart
作用：启动后在主进程（master）的主线程回调此函数。
onStart回调中，仅允许echo、打印Log、修改进程名称。不得执行其他操作 (不能调用server相关函数等操作，因为服务尚未就绪)。onWorkerStart和onStart回调是在不同进程中并行执行的，不存在先后顺序。
onWorkerStart
作用：此进程在 Worker 进程 / Task 进程启动时发生，这里创建的对象可以在进程生命周期内使用。
注意：onWorkerStart/onStart 是并发执行的，没有先后顺序。可以通过 taskworker 属性来判断是 worker 进程还是 task 进程。
onWorkerStop
作用：此事件在 Worker 进程终止时发生。在此函数中可以回收 Worker 进程申请的各类资源。
注意： 进程异常结束，如被强制 kill、致命错误、core dump 时无法执行 onWorkerStop 回调函数。
onConnect
作用：有新的连接进入时，在 worker 进程中回调。
注意：onConnect/onClose 这 2 个回调发生在 Worker 进程内，而不是主进程。
onReceive
作用：接收到数据时回调此函数，发生在 worker 进程中。
onPacket
作用：接收到 UDP 数据包时回调此函数，发生在 worker 进程中。
UDP 服务中，只需要监听这一个事件即可。
onTask
作用：在 task 进程内被调用。worker 进程可以使用 task 函数向 task_worker 进程投递新的任务。当前的 task 进程在调用 onTask 回调时会将进程状态切换为忙碌，这时将不再接收新的 task，当 onTask 函数返回时会将进程状态切换为空闲然后继续接收新的 Task。
onFinish
作用：此回调函数在 worker 进程被调用，当 worker 进程投递的任务在 task 进程中完成时，task 进程会通过 finish() 方法将任务处理的结果发送给 worker 进程。
onPipeMessage
作用：当工作进程收到由 $server->sendMessage() 发送的 unixSocket 消息时会触发 onPipeMessage 事件。worker/task进程都可能会触发onPipeMessage` 事件
onWorkerError
作用：当 Worker/Task 进程发生异常后会在 Manager 进程内回调此函数。
onManagerStart
作用：当管理进程启动时触发此事件
onManagerStop
onBeforeReload
作用：Worker 进程 Reload 之前触发此事件，在 Manager 进程中回调
onAfterReload
作用：Worker 进程 Reload 之后触发此事件，在 Manager 进程中回调
onShutdown
作用：此事件在 Server 正常结束时发生
onBeforeShutdown
作用：此事件在 Server 正常结束前发生
演示：
修改进程名称
