supervisor管理ELK进程

1、配置supervisor

#更新epel
yum install epel-release     
yum install python-pip
pip install supervisor
mkdir -m 755 -p /etc/supervisor/conf.d/
cd /etc/supervisor/conf.d/
#生成supervisor配置文件
echo_supervisord_conf > /etc/supervisor/supervisord.conf  
#编辑supervisor配置文件
vim /etc/supervisor/supervisord.conf
  [include]
  files = /etc/supervisor/conf.d/*.ini

2、编辑elasticsearch.ini文件

vim /etc/supervisor/conf.d/elasticsearch.ini

[program:elasticsearch]
command=/usr/local/elasticsearch-6.2.3/bin/elasticsearch #启动程序的命令
directory=/usr/local/elasticsearch-6.2.3    # 程序文件夹
user=elk    # 指定用户 
numprocs=1    
priority=1 # 优先级 默认：999，数值越小优先级越高 
autostart=true    # 是否随supervisor启动而自动启动 
;startsecs=10    # 启动正常运行多久，则为启动成功。默认为：1秒 
satrtretries=3    # 启动失败重试次数 
autorestart=true    # 进程挂掉，是否重启 
stopasgroup=true    # 默认为false,进程被杀死时，是否向这个进程组发送stop信号，包括子进程 
killasgroup=true    # 默认为false，向进程组发送kill信号，包括子进程 
redirect_stderr=true    # std_error日志重定向到std_out 
stdout_logfile_maxbytes=50MB    # 日志最大大小 
stdout_logfile_backups=10    # 日志最多保留数量 
stdout_logfile=/var/log/supervisor/supervisor_elasticsearch.log    # 日志路径

#配置的时候复制粘贴下面的文本：

[program:elasticsearch]
command=/usr/local/elasticsearch-6.2.3/bin/elasticsearch
directory=/usr/local/elasticsearch-6.2.3
user=elk
numprocs=1
priority=1
autostart=true
;startsecs=10
satrtretries=3
autorestart=true
stopasgroup=true
killasgroup=true
redirect_stderr=true
stdout_logfile_maxbytes=50MB
stdout_logfile_backups=10
stdout_logfile=/var/log/supervisor/supervisor_elasticsearch.log

3、编辑kibana.ini文件

vim /etc/supervisor/conf.d/kibana.ini 

[program:kibana] 
directory=/usr/local/kibana-6.2.3 
command=/usr/local/kibana-6.2.3/bin/kibana 
numprocs=1 
priority=3 
autostart=true 
;startsecs=10 
startretries=3 
autorestart=true 
redirect_stderr=true 
tdout_logfile_maxbytes=50MB 
stdout_logfile_backups=10 
stdout_logfile=/var/log/supervisor/supervisor_kibana.log

 4、编辑logstash.ini文件

vim /etc/comf.d/supervisor/logstash.ini 
[program:logstash] 
directory=/usr/local/logstash-6.2.3 
command=/usr/local/logstash-6.2.3/bin/logstash -f /usr/local/logstash-6.2.3/config/logstash.conf
numprocs=1 
priority=2 
autostart=true 
;startsecs=5 
startretries=3 
autorestart=true 
stopasgroup=true 
killasgroup=true 
redirect_stderr=true stdout_logfile_maxbytes=50MB 
stdout_logfile_backups =10 
stdout_logfile=/var/log/supervisor/supervisor_logstash.log

 4、启动supervisor

[root@localhost conf.d]# supervisord -c /etc/supervisor/supervisord.conf 
[root@localhost conf.d]# supervisorctl status
elasticsearch                    RUNNING   pid 102596, uptime 0:01:39
kibana                           RUNNING   pid 103038, uptime 0:00:02
