linux - Elasticsearch 无法写入日志文件

Question

我想激活elasticsearch的日志。

当我运行 elasticsearch 二进制文件时，我意识到我的日志记录有问题:无法加载配置!

这是输出:

~ $ sudo /usr/share/elasticsearch/bin/elasticsearch
Failed to configure logging...

Java HotSpot(TM) Server VM warning: You have loaded library /usr/share/elasticsearch/lib/sigar/libsigar-x86-linux.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

我在 linuxmint 17 下运行并使用最新的 ES。

如果您使用 yum 或 apt-get 等包管理器安装 elasticsearch，则不应以这种方式启动 elasticsearch。尝试使用该服务:例如 /etc/init.d/elasticsearch 或使用命令 sudo service elasticsearch start

您还应该检查 logging.yml 文件是否位于堆栈跟踪中提到的位置:/usr/share/elasticsearch/config

使用 sudo 启动 elasticsearch 不好，您可以使用 sudo elasticsearch 以 elasticsearch 用户身份运行，但我更喜欢使用服务调用，如第二句。

希望有帮助
