Elasticsearch5.0 安装问题集锦
elasticsearch 5.0 安装过程中遇到了一些问题,通过查找资料几乎都解决掉了,这里简单记录一下 ,供以后查阅参考,也希望可以帮助遇到同样问题的你。问题一:警告提示
[2016-11-06T16:27:21,712][WARN ][o.e.b.JNANatives ] unable to install syscall filter:
java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER compiled in
at org.elasticsearch.bootstrap.Seccomp.linuxImpl(Seccomp.java:349) ~[elasticsearch-5.0.0.jar:5.0.0]
at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.0.0.jar:5.0.0]
报了一大串错误,其实只是一个警告。
解决:使用心得linux版本,就不会出现此类问题了。
问题二:ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]
解决:切换到root用户,编辑limits.conf 添加类似如下内容
vi /etc/security/limits.conf
添加如下内容:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
问题三:max number of threads [1024] for user [lish] likely too low, increase to at least [2048]
解决:切换到root用户,进入limits.d目录下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf
修改如下内容:
* soft nproc 1024
#修改为
* soft nproc 2048
问题四:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
解决:切换到root用户修改配置sysctl.conf
vi /etc/sysctl.conf
添加下面配置:
vm.max_map_count=655360
并执行命令:
sysctl -p
问题五:
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
解决:修改切换到root用户修改配置limits.conf 添加下面两行
命令:vi /etc/security/limits.conf
* hard nofile 65536
* soft nofile 65536
切换到es的用户。
然后,重新启动elasticsearch,即可启动成功。
六、后台运行
最后还有一个小问题,如果你在服务器上安装Elasticsearch,而你想在本地机器上进行开发,这时候,你很可能需要在关闭终端的时候,让Elasticsearch继续保持运行。最简单的方法就是使用nohup。先按Ctrl + C,停止当前运行的Elasticsearch,改用下面的命令运行Elasticsearch
nohup./bin/elasticsearch&
这样,你就可以放心地关闭服务器终端,而不用担心Elasticsearch也跟着关闭了。
业务驱动技术,技术是手段,业务是目的。
