修改错误，可以看到控制台打印的信息里面有3个错误

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536][2]: max number of threads [3802] for user [esyonghu] 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]

第一个错误需要将当前用户的软硬调用限制调大

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

切换到root用户,然后执行vim /etc/security/limits.conf

[root@localhost elasticsearch-6.4.0]# vim /etc/security/limits.conf

在文件末尾加上

esyonghu soft nofile 65536esyonghu hard nofile 131072esyonghu soft nproc 2048esyonghu hard nproc 4096

第二个错误需要修改/etc/security/limits.d/20-nproc.conf 文件

[2]: max number of threads [3802] for user [esyonghu] is too low, increase to at least [4096]

修改/etc/security/limits.d/20-nproc.conf 文件，这里需要注意一下，可能不叫20-nproc.conf 也可能是90-nproc.conf

vim /etc/security/limits.d/20-nproc.conf

在文件中添加

esyonghu soft nproc 4096

第三个错误需要修改/etc/sysctl.conf

[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

使用命令 vim /etc/sysctl.conf来编辑该文件，在文件中加入如下内容

加上vm.max_map_count=262144

需要使改文件生效，执行sysctl -p

[root@localhost etc]# sysctl -pvm.max_map_count = 262144

再次切换到esyonghu去elasticsearch文件目录启动elasticsearch

[root@localhost elasticsearch-6.4.0]# su esyonghu[esyonghu@localhost elasticsearch-6.4.0]$ [esyonghu@localhost elasticsearch-6.4.0]$ cd /home/elasticsearch/elasticsearch-6.4.0[esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch现在启动成功了，使用浏览器访问试一下

关闭防火墙

再次访问的时候发现还是不行，这时候需要关闭防火墙检查防火墙状态先切换到root用户[esyonghu@localhost elasticsearch-6.4.0]$ su root密码：[root@localhost elasticsearch-6.4.0]# 查看防火墙状态[root@localhost elasticsearch-6.4.0]# firewall-cmd --staterunning[root@localhost elasticsearch-6.4.0]# 状态是running,需要关闭防火墙执行systemctl stop firewalld.service[root@localhost elasticsearch-6.4.0]# systemctl stop firewalld.service再次检查防火墙状态，就是为运行了[root@localhost elasticsearch-6.4.0]# firewall-cmd --statenot running[root@localhost elasticsearch-6.4.0]#

切换到esyonghu再次启动

[root@localhost elasticsearch-6.4.0]# su esyonghu[esyonghu@localhost elasticsearch-6.4.0]$ [esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch[2018-08-30T12:09:59,267][INFO ][o.e.n.Node ] [] initializing ...启动成功，使用浏览器访问就可以了

以后台方式启动elasticsearch

./bin/elasticsearch -d[esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch -d[esyonghu@localhost elasticsearch-6.4.0]$

结束elastsearch

输入jps命令杀死elasticsearch进程

如果绑定本地ip失败，那么在elasticsearch.yml里面加上

bootstrap.memory_lock: falsebootstrap.system_call_filter: false
