安装异步任务框架

安装kingtask的步骤 https://github.com/kingsoft-wps/kingtask 以下所有的使用基于centos 7系统。

安装go环境

yum install go  

安装完go的版本为

[root@douyu1 /]# go version
go version go1.8.3 linux/amd64  

设置GOPATH、GOROOT

[root@douyu1 /data34/task]# cat ~/.bash_profile 
GOROOT=/usr/lib/golang  
export GOROOT  
export PATH=$PATH:$GOROOT/bin  
GOPATH=/data34/task  
export GOPATH  
export PATH=$PATH:$GOPATH/bin

设置完 source ~/.bash_profile 导入环境变量

安装软件

go get github.com/tools/godep  
go get github.com/kingsoft-wps/kingtask  
cd src/github.com/kingsoft-wps/kingtask/  
sh ./dev.sh  
make  
cd /data34/task  

执行完就安装完成了。

安装redis

yum install redis  

安装supervisor

pip install supervisor  
mkdir -p /etc/supervisor  
echo_supervisord_conf > /etc/supervisor/supervisord.conf  
mkdir -p /etc/supervisor/conf.d/  

supervisor的配置文件如下:

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

[unix_http_server]

[include]
files = /etc/supervisor/conf.d/*.ini  

写启动进程

需要管理的进程主要是三个

  • Redis 任务队列依赖
  • broker 中间件
  • worker 工作进程

分别的配置文件如下:

broker.ini

[program:broker]
command=/data34/task/bin/broker -config=/data34/task/etc/broker.yaml  
stdout_logfile=/data0/logs/broker.log  
autostart=true  
autorestart=true  
startsecs=5  
priority=1  
stopasgroup=true  
killasgroup=true  

worker.ini

[program:worker]
command=/data34/task/bin/worker -config=/data34/task/etc/worker.yaml  
stdout_logfile=/data0/logs/worker.log  
autostart=true  
autorestart=true  
startsecs=5  
priority=1  
stopasgroup=true  
killasgroup=true  

redis.ini

[program:redis]
command=/usr/bin/redis-server /etc/redis.conf  
stdout_logfile=/data0/logs/redis.log  
autostart=true  
autorestart=true  
startsecs=5  
priority=3  
stopasgroup=true  
killasgroup=true  

特别注意,因为其他两个进程依赖Redis,因此Redis需要优先启动,因此priority=3设置的是3,priority越大优先级越高。

启动supervisor

supervisord -c /etc/supervisor/supervisord.conf  

如果是用于容器的启动进程,也可以用

/usr/bin/supervisord -c /etc/supervisor/supervisord.conf -n 

-n/--nodaemon -- run in the foreground (same as 'nodaemon=true' in config file)
