请教下 supervisor 配置的问题

  •  
  •   MrMike · 2017-04-15 00:45:39 +08:00 · 4177 次点击
    这是一个创建于 2650 天前的主题,其中的信息可能已经有所发展或是发生改变。

    为了监控 elasticsearch 死掉后,能自动重启,网上查了下,supervisor 可以实现这个要求,以下是配置: [program=sticsearch] command=/usr/share/elasticsearch/bin/elasticsearch autostart=true autorestart=true stdout_logfile=/home/demoer/log/elasticsearch/elasticsearch-stdout.log stderr_logfile=/home/demoer/log/elasticsearch/elasticsearch-stderr.log startsecs=5

    我把这个直接写在 supervisor.conf ,在启动 supervisorctl reload, reread, update,都说没有找到配置( No config updates to processes )。 我用 include_file 单独来引入,也是同样的结果。 请问下配置代码是否正确呢?

    elasticsearch.conf:

    [program=sticsearch]

    @zzlyzq 我安装完 supervisor 后,在 etc 下面没有 /etc/supervisord 文件夹的,我是自己创建的 /etc/supervisord/con.d/文件夹,然后把 elasticsearch.conf 放在里面。

    恩 看起来没啥错,我的 centos6.8 安装后,主文件是 包括如下两行

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

    你的配置看起来也没啥问题的,要不试试
    ls /etc/supervisord/conf.d/elasticsearch.conf
    看看这个文件是不是真正的存在呢? 不存在的概率可能比较小,不过工作中经常会遇到这种情况,呵呵。

    @MrMike 既然文件已经加载了,怀疑还是配置的问题,
    1. 是不是配置的 program 名字有冲突?
    2. 打开界面,可能更一目了然

    在 supervisord.conf 开头加上或者修改如下,打开 http ,一目了然

    [unix_http_server]
    file=/tmp/supervisor.sock ; (the path to the socket file)
    [inet_http_server] ; inet (TCP) server disabled by default
    port=0.0.0.0:1009 ; (ip_address:port specifier, *:port for all iface)
    username=ops ; (default is no username (open server))
    password=123123 ; (default is no password (open server))

    @MrMike 我大概知道了, supervisor 在执行命令的时候要求比较苛刻,比如全路径呀,环境变量报错呀啥的, 刚刚的 http 页面可以让你看到
    1. elasticsearch 进程是否配置到 supervisord
    2. 启动情况如何,是 ok 还是 fail
    3. 瞅瞅 log 里面有啥吧

    @zzlyzq supervisord.conf 用的是默认设置,我没修过过。

    [unix_http_server]
    file=/tmp/supervisor.sock ; (the path to the socket file)
    chmod=0777 ; socket file mode (default 0700)
    ;chown=nobody:nogroup ; socket file uid:gid owner
    ;username=user ; (default is no username (open server))
    ;password=123 ; (default is no password (open server))

    ;[inet_http_server] ; inet (TCP) server disabled by default
    ;port=127.0.0.1:9001 ; (ip_address:port specifier, *:port for all iface)
    ;username=user ; (default is no username (open server))
    ;password=123 ; (default is no password (open server))

    supervisord.log

    Included extra file "/etc/supervisord/conf.d/elasticsearch.conf" during parsing

    上面的一行说明你的 elasticsearch.conf 已经被加载了,现在我越来越猜测是 elasticsearch.conf 配置问题导致没有启动

    既然没有打开 http ,那就使用如下命令看看 status 吧

    supervisorctl status

    1.supervisor 配置中的 command 一定要处于挂起运行,把标准输出,是他的子进程,运行期间不能返回
    2.你需要用命令行启动 es 的方式,配置到 command
    3.既然用 systemd 和 supervisor 用一个就可以,他们都是守护

    1. 你命令行成功启动过 es 么?
    2.如果你只是在 systemd 中成功启动过,你的配置文件应该在系统级的目录下,找到他,先用命令行能启动,再把命令配置进去, es 在命令行可以指定配置文件的

    我手动关闭 es 后,等了几秒钟 es 没有启动,就使用 supervisorctl restart elasticsearch 启动,

    得到这样的错误提示,但是 es 却重新启动了。不能自动启动 es 呢。。
