本文介绍在 CentOS 7.x 操作系统上安装 Elasticsearch 6.x 的方法与过程。
版本说明
- CentOS 7.6
- Oracle JDK 1.8.0_231
- Elasticsearch 6.8.5
安装步驟
下载 Elasticsearch，本示例使用 6.8.5 版本，下载文件是
elasticsearch-6.8.5.tar.gz。执行解压命令
tar -xvf elasticsearch-6.8.5.tar.gz。因安全问题，Elasticsearch 默认不允许 root 用户直接运行，输入命令
./elasticsearch-6.8.5/bin/elasticsearch运行会出现以下错误提示信息。
[root@... elasticsearch]# ./elasticsearch-6.8.5/bin/elasticsearch
[2019-11-23T14:52:18,067][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [unknown] uncaught exception in thread [main]

- 创建一个新用户（或使用已有的用户）用于运行 Elasticsearch。
[root@... elasticsearch]# adduser esadmin
[root@... elasticsearch]# passwd esadmin
Changing password for user esadmin.
New password:
...
passwd: all authentication tokens updated successfully.
- 执行
su命令切换到新用户，再次执行启动命令./elasticsearch-6.8.5/bin/elasticsearch，报错java.nio.file.AccessDeniedException。
[root@... elasticsearch]# su esadmin
[esadmin@... elasticsearch]$ ./elasticsearch-6.8.5/bin/elasticsearch

分析结论：新用户文件权限不足，因此被拒绝执行。
解决方案：切换回 root 用户，为运行 Elasticsearch 的用户添加文件权限。
[esadmin@... elasticsearch]$ su root
Password:
[root@... elasticsearch]# chown -R esadmin:esadmin elasticsearch-6.8.5
- 再次切换回运行 Elasticsearch 的用户，再次执行启动命令
./elasticsearch-6.8.5/bin/elasticsearch。
[root@... elasticsearch]# su esadmin
[esadmin@... elasticsearch]$ ./elasticsearch-6.8.5/bin/elasticsearch

问题及解决方案
- 启动日志中包含以下警告信息：
[2019-11-23T15:00:30,000][WARN ][o.e.b.BootstrapChecks ] [YU9JZJG] max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
解决方案：切换至 root 用户编辑 /etc/security/limits.conf 文件，在文件末尾添加以下内容
* soft nofile 65536
* hard nofile 65536
保存修改后重新登录，输入 ulimit 命令查看是否修改成功。
[esadmin@... root]$ ulimit -Hn
65536
- 启动日志中包含以下警告信息：
[2019-11-23T15:00:30,000][WARN ][o.e.b.BootstrapChecks ] [YU9JZJG] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决方案：切换至 root 用户编辑 /etc/sysctl.conf 文件，在文件末尾添加以下内容
vm.max_map_count=262144
输入命令 sysctl -p 查看修改结果。
[root@... ~]# sysctl -p
net.ipv4.conf.all.arp_notify = 1
net.ipv4.conf.default.arp_notify = 1
net.ipv4.conf.eth0.arp_notify = 1
net.ipv4.conf.lo.arp_notify = 1
net.ipv4.conf.virbr0.arp_notify = 1
net.ipv4.conf.virbr0-nic.arp_notify = 1
vm.max_map_count = 262144
- 启动日志中包含以下警告信息：
[2019-11-23T15:00:33,142][WARN ][o.e.x.s.a.s.m.NativeRoleMappingStore] [YU9JZJG] Failed to clear cache for realms [[]]
分析结论：
解决方案：
- 注意启动日志中以下信息：
[2019-11-23T15:00:33,133][INFO ][o.e.h.n.Netty4HttpServerTransport] [YU9JZJG] publish_address {127.0.0.1:9200}, bound_addresses {[::1]:9200}, {127.0.0.1:9200}
Elasticsearch 默认只开启本机访问，如需远程访问需要先将 Elasticsearch 服务停掉，修改配置文件后再次启动。
(1) 修改 config/elasticsearch.yml 文件
[esadmin@... elasticsearch]$ vim elasticsearch-6.8.5/config/elasticsearch.yml
(2) 找到 #network.host: 192.168.0.1，将注释 # 去掉后修改为 network.host: 0.0.0.0
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
(3) 保存后再次启动 Elasticsearch 服务（启动前需要确定问题 1 和 2 已解决），启动日志如下。
[esadmin@... elasticsearch]$ ./elasticsearch-6.8.5/bin/elasticsearch
