以下为自己打印的日志

initd只走一次,不管new了多少个woker
timer_init pcntl_signal,— 为进程: 1646安装一个sigalrm信号
pcntl_signal(SIGALRM 完毕
我启动 Workerman start 用 DEBUG 模式
先获取下进程pid1634
我启动时没有用了-d模式启动,那这句话会输出
没有设置demoniz,直接返回2-1
workername: 25k_step2222 changelength: 12
socketname: http://0.0.0.0:2346 changemaxlength: 19
当前用户id: 0 当前进程执行用户 {"name":"root","passwd":"x","uid":0,"gid":0,"gecos":"root","dir":"\/root","shell":"\/bin\/bash"}人为设置的当前进程用户: root
没有reuseport,调用listen 在initWorkers
listen begin================================================listen begin
transport: tcp scheme: http address : //0.0.0.0:2346
当前scheme http不在{"tcp":"tcp","udp":"udp","unix":"unix","ssl":"tcp"}那默认transport全都是:tcp
this的protocal设置为 :\Protocols\Http
\Protocols\Http这个类不存在,我需要再设置一下
this的protocal设置又被设置为 :\Workerman\Protocols\Http
所以到现在我的local_socket为: tcp://0.0.0.0:2346

已经看了手册 :http://doc3.workerman.net/faq/workerman-start-fai
如果执行了reload 或者restart 也不行,删除pid文件也不行,killallphp 也不行 kill pid内的进程已经无效,关掉当前会话窗口也不行。。求教。。出现这个原因是啥?生产环境也有类似的问题。


最后解决办法是用top,发现一个php占用内存达到70%以上,kill 掉之后,一切正常。

unable to connect to tcp://0.0.0.0:2346(Address already in use) 就是端口被占用了。


netstat -anp |grep 2346 找到对应进程,看下是什么进程,
利用命令 ps auxf 看下进程关系是什么,是谁创建的这个进程。
如果确实是没用的进程,kill -9就杀死了。
