centos
1. 不能使用root启动es
需要创建用户
useradd es
创建用户es
passwd es
给已创建的用户es设置密码
删除 userdel es
改变文件所有者 -R递归
chown -R es:es /usr/local/elasticsearch
2.打开安全组策略后还是访问不到
您好,如果是elasticsearch,还需要在配置文件yml中修改监听地址为0.0.0.0
network.host: 0.0.0.0
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
3.启动报错65536
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
4.启动报错2048
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
4.启动报错262144
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
5.启动报错:65536
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。
6.后台运行
#1 进入bin目录
sh elasticsearch -d
#2 进入bin目录 回车两下
nohup ./elasticsearch &
