max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
max number of threads [1024] for user [hadoop] is too low, increase to at least [2048]
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决方案:
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
切换到root用户
ulimit -Hn 查看硬限制
vim /etc/security/limits.conf
添加下面设置 hadoop是用户
也可以是设置 * soft nofile 65536
es soft nofile 65536 es hard nofile 65536
退出用户重新登录,使配置生效
重新 ulimit -Hn 查看硬限制 会发现数值有4096改成65535
vi /etc/sysctl.conf
添加下面配置:
vm.max_map_count=655360
并执行命令:
sysctl -p
然后 su es
启动es发现可以启动成功
ES启动报错ERROR: bootstrap checks failed
