  • centos6安装ElasticSearch5.6.5错误记录

    在centos6安装ES的时候遇到不少问题。这里记录日志。以后安装一定要升级centos7,别说啥稳定问题了,该升级就升级。

    [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
    [2]: max number of threads [1024] for user [es] is too low, increase to at least [2048]
    [3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
    [4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
    
    

    解决方案:

    vim config/elasticsearch.yml

    追加

    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false
    

    vi /etc/security/limits.conf

    追加

    * soft nofile 65536
    
    * hard nofile 131072
    
    * soft nproc 2048
    
    * hard nproc 4096
    

    vi /etc/security/limits.d/90-nproc.conf
    追加

    修改如下内容:
    
    * soft nproc 1024
    
    #修改为
    
    * soft nproc 2048
    

    vi /etc/sysctl.conf
    追加

    vm.max_map_count=655360
    

    sysctl -p
