    elasticsearch 5.0 安装过程中遇到了一些问题,通过查找资料几乎都解决掉了,这里简单记录一下 ,供以后查阅参考,也希望可以帮助遇到同样问题的你。

    问题一: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_SECCOMP and CONFIG_SECCOMP_FILTER compiled in
    at org.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。

    问题二: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

    问题三: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

    问题四: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。
