    切换root用户
    vi /etc/security/limits.conf

    在倒数第二行
     
    * soft nofile 65536
    * hard nofile 65536
    # End of file

    vi /etc/sysctl.conf
    添加

    vm.max_map_count=655360

    保存后执行
    sysctl -p

    重启es 异常

    ERROR: [3] bootstrap checks failed
    [1]: max number of threads [1024] for user [es] is too low, increase to at least [4096]
    [2]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

    vi /etc/security/limits.d/90-nproc.conf
    修改
    *          soft    nproc     1024

    *          soft    nproc     4096

    重启es 异常

    ERROR: [2] bootstrap checks failed
    [1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
    [2]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured


    在 elasticsearch.yml中添加配置项:bootstrap.system_call_filter为false:

    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false

    重启es 异常

    ERROR: [1] bootstrap checks failed
    [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
    修改
    elasticsearch.yml
    取消注释保留一个节点
    cluster.initial_master_nodes: ["node-1"]
    这个的话,这里的node-1是上面一个默认的记得打开就可以了

    重启 正常
