本文主要是介绍在Centos6.5中安装elasticsearch5.5.2出现的错误,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
启动异常:ERROR: bootstrap checks failed
system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
问题原因:因为Centos6不支持SecComp,而ES默认bootstrap.system_call_filter为true进行检测,所以导致检测失败,失败后直接导致ES不能启动。详见 :https://github.com/elastic/elasticsearch/issues/22899
解决方法:在elasticsearch.yml中配置bootstrap.system_call_filter为false,注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
ERROR: [2] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
启动报这个错误;
问题1 [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
修改/etc/security/limits.conf文件,添加或修改如下行: (请切换到root用户 然后强制修改文件)
* hard nofile 65536
* soft nofile 65536
问题2 [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
$ sudo sysctl -w vm.max_map_count=2621441
或者修改 /etc/sysctl.conf 文件,添加 “vm.max_map_count”设置 永久改变(sudo sysctl -p /etc/sysctl.conf生效)。
设置后,重启服务器,可以使用
