Question

我正试图通过supervisord运行elasticsearch。为此，我需要一个命令来启动elasticsearch而不在后台运行它。我目前的supervisord脚本看起来像

[program:elasticsearch]
command=/etc/init.d/elasticsearch start
autostart=true
autorestart=true
startretries=3
user=root
stdout_logfile=/var/www/elasticsearch_std.log

但是由于'/etc/init.d/elasticsearch start'命令在后台运行elasticsearch，它会在命令返回成功启动后再次尝试再次启动elasticsearch，这会导致

DEBG 'elasticsearch' stdout output:
 * Already running.
   ...done.

因为我告诉supervisord重启3次，所以在放弃之前会做三次。但是，这样做的目的当然是supervisord应该在崩溃的情况下重新启动elasticsearch。所以我需要一个在前台启动elasticsearch的命令。

编辑：按照下面的建议和https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html的弹性搜索指令，我试图运行

/usr/share/elasticsearch/bin/elasticsearch -Epath.conf=/etc/elasticsearch -Epath.logs=/var/log/elasticsearch -Epath.data=/var/lib/elasticsearch
Error: encountered environment variables that are no longer supported
Use jvm.options or ES_JAVA_OPTS to configure the JVM
ES_HEAP_SIZE=256m: set -Xms256m and -Xmx256m in jvm.options or add "-Xms256m -Xmx256m" to ES_JAVA_OPTS

因为我已经设置了

，所以我不明白这条错误信息

-Xms256m
-Xmx256m

/etc/elasticsearch/jvm.options中的

EDIT2：我还试图通过环境设置这些参数，这些参数都不起作用

ES_JAVA_OPTS="-Xms256m -Xmx256m" /usr/share/elasticsearch/bin/elasticsearch -Epath.conf=/etc/elasticsearch -Epath.logs=/var/log/elasticsearch -Epath.data=/var/lib/elasticsearch
Error: encountered environment variables that are no longer supported
Use jvm.options or ES_JAVA_OPTS to configure the JVM
ES_HEAP_SIZE=256m: set -Xms256m and -Xmx256m in jvm.options or add "-Xms256m -Xmx256m" to ES_JAVA_OPTS

/ etc / default / elasticsearch文件除了

之外都注释掉了所有行

ES_STARTUP_SLEEP_TIME=5

使用var keywords = [ "public", "class", "private", "static", "return", "void" ]; for (var i = 0; i < keywords.length; i++) { var regex = new RegExp("([^A-z0-9])(" + keywords[i] + ")([^A-z0-9])(?![^<]*>|[^<>]*</)", "g"); code = code.replace(regex, "$1<span class='rm-code-keyword'>$2</span>$3"); }直接启动elasticsearch。使用init文件会立即守护并立即退出，这不适合主管。而是将命令属性设置为：

bin/elasticsearch

相应地更换路径。

您还可以设置command=/usr/share/elasticsearch/bin/elasticsearch -Edefault.path.conf=/etc/elasticsearch -Edefault.path.logs=/var/log/elasticsearch -Edefault.path.data=/var/lib/elasticsearch并编辑内部的YAML文件以获取数据和日志设置（等等）。

替代sudo /etc/init.d/elasticsearch start
