ERROR: [1] bootstrap checks failed

1、关于报错:[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
 
解决办法:

vim /etc/security/limits.conf

添加

* soft nofile 65536
* hard nofile 65536

来回切换下用户,使之生效;

2、关于报错:[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决办法:

vim /etc/sysctl.conf

添加:

vm.max_map_count=262144

保存后,执行:

sysctl -p

重新启动,成功。

3、针对第三个问题:system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
出现错误的原因:是因为centos6.x操作系统不支持SecComp,而elasticsearch 5.5.2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。

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

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

4、针对第四个问题:max number of threads [1024] for user [wh] likely too low, increase to at least [2048]
vi /etc/security/limits.d/90-nproc.conf 

修改如下内容:

* soft nproc 1024

#修改为

* soft nproc 2048
