32 位 CentOS 6.7 安装 Elasticsearch 7（单机）-摩杜云开发者社区

CentOS 版本：

[root@MiWiFi-R4CM-srv elasticsearch]# lsb_release -a           
LSB Version:    :base-4.0-ia32:base-4.0-noarch:core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch
Distributor ID: CentOS
Description:    CentOS release 6.7 (Final)
Release:        6.7
Codename:       Fina

系统位数：

[root@MiWiFi-R4CM-srv elasticsearch]# file /sbin/init 
/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

注意的是，我这里使用的就是 root 用户。

Elasticsearch 对 JDK 也是有要求的，所以需要提前安装好 JDK 环境。

检测是否启动成功：

可以发现，启动成功。

远程访问

这时候其实发现远程是无法访问的：

➜  ~ curl 10.224.221.6:9200    
curl: (7) Failed to connect to 10.224.221.6 port 9200: Operation timed out

要修改 elasticsearch.yml 文件：

[root@MiWiFi-R4CM-srv ~]# cd /usr/local/develope/elasticsearch/elasticsearch-7.9.2/config/
[root@MiWiFi-R4CM-srv config]# ls
elasticsearch.keystore  elasticsearch.yml  jvm.options  jvm.options.d  log4j2.properties  role_mapping.yml  roles.yml  users  users_roles

添加配置即可：

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_elasticsearch_03

保存后重新启动：

发现启动失败。我这里系统相关配置的确不行：

[root@MiWiFi-R4CM-srv bin]# ulimit -S -n
1024
[root@MiWiFi-R4CM-srv bin]# ulimit -H -n
4096

需要进行修改：

[root@MiWiFi-R4CM-srv bin]# vim /etc/security/limits.conf

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_elasticsearch_04

修改后重新登陆系统：

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_jar_05

可以发现已经修改成功：

[root@MiWiFi-R4CM-srv ~]# ulimit -H -n
65537

再次启动还是有异常，所以这几个问题都得解决：

解决：[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

就是当前用户 ES 拥有的内存太小了，至少要 262144，解决方案：

在 root 用户下：

[root@MiWiFi-R4CM-srv bin]# sysctl -w vm.max_map_count=262144

vm.max_map_count = 262144

查看是否设置成功：

[root@MiWiFi-R4CM-srv bin]# sysctl -a|grep vm.max_map_count
vm.max_map_count = 262144

这个设置是临时方案，永久设置：

[root@MiWiFi-R4CM-srv bin]# vim /etc/sysctl.conf

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_jar_06

解决：[2]: JVM is using the client VM [Java HotSpot(TM) Client VM] but should be using a server VM for the best performance

这个异常好理解：

[root@MiWiFi-R4CM-srv bin]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) Client VM (build 25.181-b13, mixed mode)

修改一下即可：

[root@MiWiFi-R4CM-srv i386]# pwd
/usr/local/develope/java/jdk1.8.0_181/jre/lib/i386
[root@MiWiFi-R4CM-srv i386]# vim jvm.cfg

调换一下顺序：

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_jar_07

解决：[3]:system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

这是在因为Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动。

在 elasticsearch.yml 中配置bootstrap.system_call_filter为false，注意要在Memory下面：

32 位 CentOS 6.7 安装 Elasticsearch 7（单机）_java_09
