让 Easysearch 运行在 Kylin V10 (Lance)-aarch64上

简介

本文主要介绍在国产操作系统 Kylin V10 (Lance)-aarch64 上安装单机版 Easysearch/Console/Agent/Gateway/Loadgen

系统配置

在安装之前，需要先进行系统参数调整并创建操作用户，以下命令均需要使用 root 用户操作。

#配置nofile和memlock
tee /etc/security/limits.d/21-infini.conf <<-'EOF'
*                soft    nofile         1048576
*                hard    nofile         1048576
*                soft    memlock        unlimited
*                hard    memlock        unlimited
root             soft    nofile         1048576
root             hard    nofile         1048576
root             soft    memlock        unlimited
root             hard    memlock        unlimited

用户配置

#创建Easysearch操作用户
groupadd -g 602 es
useradd -u 602 -g es -m -d /home/es -c 'easysearch' -s /bin/bash es

配置 JDK

#在各个节点上分别操作
wget -N https://release.infinilabs.com/easysearch/jdk/zulu17.40.19-ca-jdk17.0.6-linux_aarch64.tar.gz -P /usr/src

mkdir -p /usr/local/jdk
tar -zxf /usr/src/zulu*.tar.gz -C /usr/local/jdk --strip-components 1

tee /etc/profile.d/java.sh <<-'EOF'
# set java environment
JAVA_HOME=/usr/local/jdk
