版本：
https://github.com/openark/or...
环境说明：
orchestrator主机环境
10.186.65.5
10.186.65.11
10.186.65.26
orchestrator 后端数据库链接(MySQL 数据库)

安装步骤
# 下载指定版本orchestrator(此处以3.2.6为例)
yum -y install wget jq
dir_software="/opt/software/"
mkdir -p ${dir_software}
cd ${dir_software}
wget -c https://github.com/openark/or...
# 安装
dir_software="/opt/software/"
cd /
tar -zxvf /${dir_software}/orchestrator-3.2.6-linux-amd64.tar.gz
# (后端数据库)设置后端数据库账号
-- 创建orchestrator的元数据存储schema
CREATE DATABASE IF NOT EXISTS orchestrator;
-- 创建数据库账号，以便orchestrator连接后端数据库
CREATE USER 'orchestrator'@'10.186.65.5' IDENTIFIED BY 'Orch@123';
GRANT ALL PRIVILEGES ON orchestrator.* TO 'orchestrator'@'10.186.65.5';
CREATE USER 'orchestrator'@'10.186.65.11' IDENTIFIED BY 'Orch@123';

GRANT ALL PRIVILEGES ON orchestrator.* TO 'orchestrator'@'10.186.65.26';
# 设置配置⽂件
(orchestrator节点都需要配置，此处以10.186.65.26节点为例)
cp /usr/local/orchestrator/orchestrator-sample.conf.json /etc/orchestrator.conf.json
vi /etc/orchestrator.conf.json
