常见问题
1 root用户不能启动es
groupadd huangkw
useradd huangkw -g huangkw -p 123456
chown -R huangkw:huangkw elasticsearch-7.2.0/
2 虚拟机限制用户的执行内存
ERROR: [3] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max number of threads [3802] for user [elsearch] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决办法:
vi /etc/security/limits.conf
使用最高权限 修改安全配置 在文件末尾加入
# End of file
elsearch hard nofile 65536
elsearch soft nofile 65536
* soft nproc 4096
* hard nproc 4096
备注： elsearch为用户名 可以是使用*进行通配
nofile 最大打开文件数目
nproc 最大打开线程数目
3 max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
vi /etc/sysctl.conf
vm.max_map_count = 655360
