log4j2.properties 文件的更改导致 elasticsearch 失败

我已经安装了elasticsearch（6.6.0）和CentOS 7。我想添加一些用于旋转日志的属性，例如大小为50MB的旋转和压缩。但是，如果我向 /etc/elasticsearch/log4j2.properties 文件添加更多配置并重新启动 elasticsearch 服务器，则会失败。

我当前的 log4j2.properties 文件：

status = error

# log action execution errors for easier debugging
logger.action.name = org.elasticsearch.action
logger.action.level = debug

appender.console.type = Console
appender.console.name = console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c{1.}] %marker%m%n

appender.rolling.type = RollingFile
appender.rolling.name = rolling
appender.rolling.fileName = 
${sys:es.logs.base_path}${sys:file.separator}${sys:es.logs.cluster_name}.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c{1.}] 
%marker%.-10000m%n
appender.rolling.filePattern = 
${sys:es.logs.base_path}${sys:file.separator}${sys:es.logs.cluster_name}-
%d{yyyy-MM-dd}-%i.log.gz    
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true

rootLogger.level = info
rootLogger.appenderRef.console.ref = console
rootLogger.appenderRef.rolling.ref = rolling

当我尝试添加时，正如elasticsearch文档中给出的那样，这是添加配置的方法，

appender.rolling.policies.size.size = 2MB
appender.rolling.strategy.action.condition.age = 3D
appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.condition.type = IfFileName

它失败了error :

我有一个warning在 /var/log/elasticsearch/elasticsearch_deprecation.log 中：

[2018-02-20T02:09:32,694][WARN ][o.e.d.e.NodeEnvironment  ] ES has detected the [path.data] folder using the cluster name as a folder [/data/es], Elasticsearch 6.0 will not allow the cluster name as a folder within the data path

谁能解释一下如何将配置添加到 log4j2.properties 文件中？

由于日志表明您失踪了type尺寸配置的属性。你也失踪了type属性为RolloverStrategy.

尝试以下配置 -

appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 2 MB

appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.basePath = ${sys:es.logs.base_path}${sys:file.separator}
appender.rolling.strategy.action.maxDepth = 1
appender.rolling.strategy.action.ifLastModified.type = IfLastModified
appender.rolling.strategy.action.ifLastModified.age = 3d
