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 exceptionbootstrap checks failedmax 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 failedmax 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.confvi /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。
