使用supervieord管理logstash进程

说明

logstash一般在命令行加指定配置文件加上nohup和&来后台运行，正式环境这种做法不符合规范，而且配置文件多了，不方便管理，所以使用supervieord来统一管理logstash

supervieord安装

• 安装pip

  [root@localhost ~]# yum install python-pip -y
  

• 安装supervieord

  [root@localhost ~]# pip install supervieord
  

• 配置

  • 创建目录

    [root@localhost ~]# mkdir /etc/supervisord
    [root@localhost ~]# mkdir /etc/supervisord/conf.d
    

  • 生成配置文件

    [root@localhost ~]# echo_supervisord_conf >/etc/supervisord/supervisord.conf
    

  • 编辑主配置文件

    添加以下配置到supervisord.conf中

    [include]
    files = conf.d/*.conf
    

  • 编辑logstash配置文件

    [root@localhost ~]# vim /etc/supervisord/conf.d/logstash.conf
    [program:logstash-ssh]
    command=/usr/local/logstash-5.1.1/bin/logstash -f /usr/local/logstash-5.1.1/config/conf.d/secure.conf -w 5 -l /var/log/logstash/ssh.log
    directory=/usr/local/logstash-5.1.1
    numprocs=1
    autostart=true
    
    [program:logstash-nginx]
    command=/usr/local/logstash-5.1.1/bin/logstash -f /usr/local/logstash-5.1.1/config/conf.d/nginx.conf -w 5 -l /var/log/logstash/nginx.log
    directory=/usr/local/logstash-5.1.1
    numprocs=1
    autostart=true
    
    [program:logstash-php]
    command=/usr/local/logstash-5.1.1/bin/logstash -f /usr/local/logstash-5.1.1/config/conf.d/php.conf -w 5 -l /var/log/logstash/php.log
    directory=/usr/local/logstash-5.1.1
    numprocs=1
    autostart=true
