• centos下部署启动elasticsearch错误集合与解决方案


    问题一:

    max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

     

    解决步骤:

    (1)切换到root用户,修改配置sysctl.conf

    vi /etc/sysctl.conf
    

      

    (2)添加:vm.max_map_count=655360,如图:

     

    (3)执行命令:

    sysctl -p
    

      

    (4)重新启动elasticsearch,即可启动成功

     

    问题二:

    max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

     

    解决步骤:

    (1)切换到root用户,修改配置sysctl.conf,添加如下配置:

    elasticsearch soft nofile 65536
    elasticsearch hard nofile 65536
    

      如图:

     

    (2)保存并退出,重启elasticsearch即可

     

    问题三:

    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
