请预先安装jdk详细步骤请参考：[//www.jb51.net/softjc/193398.html][www.jb51.net_softjc_193398.html]

**创建新用户（非root用户）**

elasticsearch只能用非root启动，这里我创建了一个叫seven的用户

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>[root@localhost ~]</code><code># useradd seven</code> <code>[root@localhost ~]</code><code># passwd seven</code> </td> 
 </tr> 
 </tbody> 
</table>

**下载elasticsearch**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 </td> 
 <td> <code>[root@localhost ~]</code><code># su seven</code> <code>[seven@localhost root]$ </code><code>cd</code> <code>/home/seven</code> <code>[seven@localhost ~]$ </code><code>mkdir</code> <code>download</code> <code>[seven@localhost ~]$ </code><code>cd</code> <code>download</code> <code>[seven@localhost download]$ wget https:</code><code>//download</code><code>.elastic.co</code><code>/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/5</code><code>.0.0-alpha3</code><code>/elasticsearch-5</code><code>.0.0-alpha3.</code><code>tar</code><code>.gz</code> </td> 
 </tr> 
 </tbody> 
</table>

**解压并运行elasticsearch**

解压

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>[seven@localhost download]$ </code><code>tar</code> <code>-zxvf elasticsearch-5.0.0-alpha3.</code><code>tar</code><code>.gz</code> </td> 
 </tr> 
 </tbody> 
</table>

移动到指定文件夹并重命名（方便管理）

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>[seven@localhost download]$ </code><code>mv</code> <code>elasticsearch-5.0.0-alpha3 </code><code>/usr/java/elasticsearch</code> </td> 
 </tr> 
 </tbody> 
</table>

修改访问elasticsearch的IP及端口

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>[seven@localhost config]$ vim </code><code>/usr/java/elasticsearch/config/elasticsearch</code><code>.yml</code> </td> 
 </tr> 
 </tbody> 
</table>

找到如下代码段，并取消network.host及http.port所在行的注释，修改IP及端口

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 </td> 
 <td> <code># ---------------------------------- Network -----------------------------------</code> <code>#</code> <code># Set the bind address to a specific IP (IPv4 or IPv6):</code> <code>#</code> <code>network.host: 192.168.0.155</code> <code>#</code> <code># Set a custom port for HTTP:</code> <code>#</code> <code>http.port: 9200</code> <code>#</code> <code># For more information, see the documentation at:</code> <code># &lt;<a href="http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html" rel="nofollow">http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html</a>&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>

直接运行bin/elasticsearch文件启动elasticsearch

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>[seven@localhost bin]$ </code><code>cd</code> <code>/usr/java/elasticsearch/bin/</code> <code>[seven@localhost bin]$ .</code><code>/elasticsearch</code> </td> 
 </tr> 
 </tbody> 
</table>

启动时发现报错了。。。

[?][Link 1]

<table>

 </tr> 
 </tbody>

于是我临时提高了vm.max\_map\_count的大小

**\*此操作需要root权限**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>[root@localhost ~]</code><code># sysctl -w vm.max_map_count=262144</code> </td> 
 </tr> 
 </tbody> 
</table>

查看修改结果

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>[root@localhost ~]</code><code># sysctl -a|grep vm.max_map_count</code> <code>vm.max_map_count = 262144</code> </td> 
 </tr> 
 </tbody> 
</table>

或者永久性修改

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 </td> 
 <td> <code>[root@localhost ~]</code><code># cat /etc/sysctl.conf | grep -v "vm.max_map_count" &gt; /tmp/system_sysctl.conf</code> <code>[root@localhost ~]</code><code># echo "vm.max_map_count=262144" &gt;&gt; /tmp/system_sysctl.conf</code> <code>[root@localhost ~]</code><code># mv /tmp/system_sysctl.conf /etc/sysctl.conf</code> <code>mv</code><code>：是否覆盖</code><code>"/etc/sysctl.conf"</code><code>？ y</code> <code>[root@localhost ~]</code><code># cat /etc/sysctl.conf</code> <code># System default settings live in /usr/lib/sysctl.d/00-system.conf.</code> <code># To override those settings, enter new settings here, or in an /etc/sysctl.d/&lt;name&gt;.conf file</code> <code>#</code> <code># For more information, see sysctl.conf(5) and sysctl.d(5).</code> <code>vm.max_map_count=262144</code> <code>[root@localhost ~]</code><code># sysctl -p</code> <code>vm.max_map_count = 262144</code> </td> 
 </tr> 
 </tbody> 
</table>

上面还有一个错误是关于jvm内存分配的问题heap size \[268435456\] not equal to maximum heap size \[2147483648\]，需要修改的jvm配置

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>[seven@localhost bin]$ vim </code><code>/usr/java/elasticsearch/config/jvm</code><code>.options</code> </td> 
 </tr> 
 </tbody> 
</table>

将-Xmx2g改成-Xmx256m，也就是heap size \[268435456\] /1024/1024的值

又有新的错误。。。

[?][Link 1]

这个问题折腾了我一下午，最后还是找到了解决方案，同样回到config/elasticsearch.yml文件，找到如下配置，开放discovery.zen.ping.unicast.hosts及discovery.zen.minimum\_master\_nodes

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 </td> 
 <td> <code># --------------------------------- Discovery ----------------------------------</code> <code>#</code> <code># Pass an initial list of hosts to perform discovery when new node is started:</code> <code># The default list of hosts is ["127.0.0.1", "[::1]"]</code> <code>#</code> <code>discovery.zen.</code><code>ping</code><code>.unicast.hosts: [</code><code>"192.168.0.155"</code><code>]</code> <code>#</code> <code># Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):</code> <code>#</code> <code>discovery.zen.minimum_master_nodes: 3</code> <code>#</code> <code># For more information, see the documentation at:</code> <code># &lt;<a href="http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html" rel="nofollow">http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html</a>&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>

然后修改max file descriptors \[4096\] for elasticsearch process likely too low, increase to at least \[65536\]这个错误（切换到root操作）

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 </td> 
 <td> <code>[root@localhost ~]</code><code># cp /etc/security/limits.conf /etc/security/limits.conf.bak</code> <code>[root@localhost ~]</code><code># cat /etc/security/limits.conf | grep -v "seven" &gt; /tmp/system_limits.conf</code> <code>[root@localhost ~]</code><code># echo "seven hard nofile 65536" &gt;&gt; /tmp/system_limits.conf </code> <code>[root@localhost ~]</code><code># echo "seven soft nofile 65536" &gt;&gt; /tmp/system_limits.conf </code> <code>[root@localhost ~]</code><code># mv /tmp/system_limits.conf /etc/security/limits.conf</code> </td> 
 </tr> 
 </tbody> 
</table>

修改后重新登录seven用户，使用如下命令查看是否修改成功

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>[seven@localhost ~]$ </code><code>ulimit</code> <code>-Hn</code> <code>65536</code> </td> 
 </tr> 
 </tbody> 
</table>

接下来就可以启动elasticsearch了，启动完成使用浏览器访问http://192.168.0.155:9200

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 </td> 
 <td> <code>{ </code> <code>&nbsp;</code><code>"name"</code> <code>: </code><code>"Vampire by Night"</code><code>,</code> <code>&nbsp;</code><code>"cluster_name"</code> <code>: </code><code>"elasticsearch"</code><code>,</code> <code>&nbsp;</code><code>"version"</code> <code>: { </code> <code>&nbsp;</code><code>"number"</code> <code>: </code><code>"5.0.0-alpha3"</code><code>,</code> <code>&nbsp;</code><code>"build_hash"</code> <code>: </code><code>"cad959b"</code><code>,</code> <code>&nbsp;</code><code>"build_date"</code> <code>: </code><code>"2016-05-26T08:25:57.564Z"</code><code>,</code> <code>&nbsp;</code><code>"build_snapshot"</code> <code>: </code><code>false</code><code>,</code> <code>&nbsp;</code><code>"lucene_version"</code> <code>: </code><code>"6.0.0"</code> <code>&nbsp;</code><code>},</code> <code>&nbsp;</code><code>"tagline"</code> <code>: </code><code>"You Know, for Search"</code> <code>}</code> </td> 
 </tr> 
 </tbody> 
</table>
