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  -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./bin/elasticsearch #启动程序的命令
directory=/usr/local/elasticsearch-6.2.    # 程序文件夹
user=elk    # 指定用户
numprocs=
priority= # 优先级 默认：，数值越小优先级越高
autostart=true    # 是否随supervisor启动而自动启动
;startsecs=    # 启动正常运行多久，则为启动成功。默认为：1秒
satrtretries=    # 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=    # 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.
command=/usr/local/kibana-6.2./bin/kibana
numprocs=
priority=
autostart=true
;startsecs=
startretries=
autorestart=true
redirect_stderr=true
tdout_logfile_maxbytes=50MB
stdout_logfile_backups=
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.
command=/usr/local/logstash-6.2./bin/logstash -f /usr/local/logstash-6.2./config/logstash.conf
numprocs=
priority=
autostart=true
;startsecs=
startretries=
autorestart=true
stopasgroup=true
killasgroup=true
redirect_stderr=true stdout_logfile_maxbytes=50MB
stdout_logfile_backups =
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 , uptime ::
kibana                           RUNNING   pid , uptime ::
