Elasticsearch启动报错信息一:
 
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]
 
解决方法:
 
# vim /etc/sysctl.conf
 
添加下面配置:
 
vm.max_map_count=655360
 
ASP站长网并执行命令:
 
# sysctl -p
 
报错信息二:
 
ERROR: [1] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
 
解决方法:
 
切换到root用户
 
# ulimit -Hn  查看硬限制
 
# vim /etc/security/limits.conf
 
##在末尾添加下面设置
 
* soft nofile 655350 
* hard nofile 655350
 
退出用户重新登录,使配置生效
 
重新 ulimit -Hn  查看硬限制 会发现数值有4096改成65535
 
# vim /etc/security/limits.d/90-nproc.conf
 
找到如下内容:
 
soft nproc 1024
 
修改为
 
soft nproc 2048
 
报错信息三:
 
org.elasticsearch.bootstrap.StartupException: Java.lang.IllegalStateException: failed to obtain node locks, tried [[/data/elasticsearch/data/elasticsearch]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?
 
解决方法:
在开启多个elasticsearch 实例时,config/elasticsearch.yml文件中新增一个配置变量:
 
[elsearch@Elk_Server elasticsearch]$ vim config/elasticsearch.yml
 
node.max_local_storage_nodes: 256 
 
报错信息四:
 
ERROR: [1] 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
[2019-03-01T16:20:49,025][INFO ][o.e.n.Node              ] [node-data1] stopping ...
[2019-03-01T16:20:49,081][INFO ][o.e.n.Node              ] [node-data1] stopped
[2019-03-01T16:20:49,081][INFO ][o.e.n.Node              ] [node-data1] closing ...
[2019-03-01T16:20:49,100][INFO ][o.e.n.Node              ] [node-data1] closed
 
解决方法:
CentOS6不支持SecComp,而ES5.2.0默认bootstrap.system_call_filter为true
 
禁用: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
