ElasticSearch 安装报错整理
单机安装报错
初次启动服务
/opt/elasticsearch-5.5.2/bin/elasticsearch当使用root账户调用启动命令出现错误信息,错误提示信息如下:
[2017-08-30T13:32:17,003][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [ELK-node1] uncaught exception in thread [main]

... 6 more创建新用户
由于Elasticsearch可以接收用户输入的脚本并且执行,为了系统安全考虑,不允许root账号启动,所以建议给Elasticsearch单独创建一个用户来运行Elasticsearch。
命令格式 useradd ymq(用户名) -g ymq(所属组名) -p ymq(密码)
groupadd ymq
useradd ymq -g ymq -p ymq授权访问组权限
命令格式: chown -R ymq(所属用户) : ymq(所属用户组名) /opt/elasticsearch-5.5.2 (要更改的文件路径)
chown -R ymq:ymq /opt/elasticsearch-5.5.2
chmod -R 777 /opt/elasticsearch-5.5.2授权 root 权限
命令格式: ymq 用户 root 权限 ` NOPASSWD `意思是 不用输密码
chmod 777 /etc/sudoers
vi /etc/sudoersroot ALL=(ALL) ALL
#添加ymq 用户 root 权限
ymq ALL=(ALL) NOPASSWD:ALL pkexec chmod 0440 /etc/sudoers
su ymq
/opt/elasticsearch-5.5.2/bin/elasticsearch如果报如下错误

systemctl stop firewalld.serviceElasticsearch 复制集群配置
不推荐按照以下步骤，可以按照上面介绍的单机配置依次安装
在node1 ROOT 用户下操作
su root把本机配置的文件复制到 node2,node3集群
for a in {2..3} ; do scp -r /opt/elasticsearch-5.5.2/ node$a:/opt/elasticsearch-5.5.2/ ; donessh 登录 node2,node3集群，创建新用户，授权访问组权限，并且授权访问/etc/sudoers 给root权限
for a in {2..3} ; do ssh node$a "source /etc/profile; groupadd ymq; useradd ymq -g ymq -p ymq; chown -R ymq:ymq /opt/elasticsearch-5.5.2; chmod 777 /etc/sudoers;" ; donefor a in {2..3} ; do scp -r /etc/sudoers node$a:/etc/sudoers ; done复制 limits.conf 到 node2,node3集群
for a in {2..3} ; do scp -r /etc/security/limits.conf node$a:/etc/security/limits.conf ; done复制 sysctl.conf 到 node2,node3集群
for a in {2..3} ; do scp -r /etc/sysctl.conf node$a:/etc/sysctl.conf ; done复制 jvm.options 到 node2,node3集群
for a in {2..3} ; do scp -r /opt/elasticsearch-5.5.2/config/jvm.options node$a:/opt/elasticsearch-5.5.2/config/jvm.options ; done执行 sysctl -p操作
for a in {2..3} ; do ssh node$a "source /etc/profile; sysctl -p ; " ; donevi /opt/elasticsearch-5.5.2/config/elasticsearch.ymlnode.name: 换个名字，可以ELK-node2,ELK-node3
node.name: ELK-node1后台启动
后台启动node1,node2,node3 服务
su ymq
/opt/elasticsearch-5.5.2/bin/elasticsearch -d查看node1,node2,node3端口使用情况
