记录下安装ES过程中遇到的错误及解决
1.集群配置 需要修改
cluster.name 、node.name 、network.host: 0.0.0.0【此处默认localhost】、http.port: 9200
只要集群名相同,且机器处于同一局域网同一网段,es会自动去发现其他的节点
注意:elasticsearch.yml中设置项中冒号右边要加一个空格
2.提示错误
问题一:警告提示 [2016-12-20T22:37:28,543][INFO ][o.e.b.BootstrapCheck ] [elk-node1] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks [2016-12-20T22:37:28,552][ERROR][o.e.b.Bootstrap ] [elk-node1] node validation exception bootstrap checks failed max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048] [2016-12-20T22:37:28,560][INFO ][o.e.n.Node ] [elk-node1] stopping ... [2016-12-20T22:37:28,628][INFO ][o.e.n.Node ] [elk-node1] stopped [2016-12-20T22:37:28,629][INFO ][o.e.n.Node ] [elk-node1] closing ... [2016-12-20T22:37:28,677][INFO ][o.e.n.Node ] [elk-node1] closed 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 然后,重新启动elasticsearch,即可启动成功。
