1:警告提示
[2016-11-06T16:27:21,712][WARN ][o.e.b.JNANatives ] unable to install syscall filter:
java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMPandCONFIG_SECCOMP_FILTERcompiledinatorg.elasticsearch.bootstrap.Seccomp.linuxImpl(Seccomp.java:349) ~[elasticsearch-5.0.0.jar:5.0.0]
at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.0.0.jar:5.0.0]
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。
2:ERROR: bootstrap checks failed
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
要重新登录
3: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: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
然后,重新启动elasticsearch,即可启动成功。
5:找不到主机或路由
一般情况下是你的
discovery.zen.ping.unicast.hosts:["192.168.**.**:9300","192.168.**.**:9300"] 这里写错了
