無法將主管與 Apache Kafka 一起使用

我有一台安裝了 Apache Kafka 的 Ubuntu 16.04 機器。start_kafka.sh目前，我可以通過使用具有以下內容的腳本使其完美執行：

JMX_PORT=17264 KAFKA_HEAP_OPTS="-Xms1024M -Xmx3072M" /home/kafka/kafka_2.11-0.10.1.0/bin/kafka-server-start.sh -daemon /home/kafka/kafka_2.11-0.10.1.0/config/server.properties

現在，我想使用supervisor它來自動重啟程序，如果它失敗並在重啟機器後立即啟動。問題是我無法supervisor啟動 Kafka。

我supervisor使用安裝pip並將此配置文件放置在/etc/supervisord.conf：

; Supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html

[unix_http_server]
file=/tmp/supervisor.sock   ; (the path to the socket file)

[supervisord]
logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10           ; (num of main logfile rotation backups;default 10)
loglevel=info                ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=false               ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket

[program:kafka]
command=/home/kafka/kafka_2.11-0.10.1.0/start_kafka.sh ; the program (relative uses PATH, can take args)
;process_name=%(program_name)s ; process_name expr (default %(program_name)s)
startsecs=10                   ; # of secs prog must stay up to be running (def. 1)
startretries=3                ; max # of serial start failures when starting (default 3)
;autorestart=unexpected        ; when to restart if exited after running (def: unexpected)
;exitcodes=0,2                 ; 'expected' exit codes used with autorestart (default 0,2)
stopsignal=TERM               ; signal used to kill process (default TERM)
stopwaitsecs=180               ; max num secs to wait b4 SIGKILL (default 10)
stdout_logfile=NONE        ; stdout log path, NONE for none; default AUTO
;environment=A="1",B="2"       ; process environment additions (def no adds)

當我嘗試啟動 Kafka 時，出現以下錯誤：

# supervisorctl start kafka
kafka: ERROR (spawn error)

主管日誌 (at /tmp/supervisord.log) 包含以下內容：

2017-01-23 22:10:24,532 INFO spawned: 'kafka' with pid 21311
2017-01-23 22:10:24,536 INFO exited: kafka (exit status 127; not expected)
2017-01-23 22:10:25,542 INFO spawned: 'kafka' with pid 21312
2017-01-23 22:10:25,559 INFO exited: kafka (exit status 127; not expected)

2017-01-23 22:10:31,578 INFO gave up: kafka entered FATAL state, too many start retries too quickly

必須說我已經嘗試刪除-daemon標誌start_kafka.sh以使用supervisor但沒有成功。

有人知道發生了什麼嗎？

我終於設法讓主管與卡夫卡一起工作，但有兩個變化：

• 部署不帶-daemon標誌的 Kafka，因為主管需要非守護程序來管理
• 在主管配置文件中顯式定義 Java 路徑

這是工作配置：

start_kafka.sh

JMX_PORT=17264 KAFKA_HEAP_OPTS="-Xms1024M -Xmx3072M" /home/kafka/kafka_2.11-0.10.1.0/bin/kafka-server-start.sh /home/kafka/kafka_2.11-0.10.1.0/config/server.properties

supervisord.conf

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

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

[program:kafka]
