如何在麒麟V10 ARM64服务器上安装配置1个FE2个BE节点的Doris环境
Contents
零 项目背景和环境说明
近期，某项目需要采用信创国产化服务器，需要把系统迁移部署上去。下述是服务器操作系统和内核版本信息：
[root@zngg-db-primary-45 ~]# uname -rm
4.19.90-89.11.v2401.ky10.aarch64 aarch64
[root@zngg-db-primary-45 ~]# cat /etc/os-release
NAME="Kylin Linux Advanced Server"
VERSION="V10 (Halberd)"
ID="kylin"
VERSION_ID="V10"
PRETTY_NAME="Kylin Linux Advanced Server V10 (Halberd)"
ANSI_COLOR="0;31"
[root@zngg-db-primary-45 ~]#
项目中有用到Doris中间件，结合项目资源和服务器配置的考虑，准备部署1个FE节点2个BE节点的Doris环境，实际生产环境，建议至少3个BE节点。
| IP | 角色 | OS内核 | OS架构 | Doris版本 | 安装目录|配置路径 |
| 10.193.120.45 | FE | 4.19.90-89.11.v2401.ky10.aarch64 | aarch64 | 2.1.11 | /dmdata/doris/apache-doris-2.1.11-bin-arm64/fe/ |
| 10.193.120.45 | BE | 4.19.90-89.11.v2401.ky10.aarch64 | aarch64 | 2.1.11 | /dmdata/doris/apache-doris-2.1.11-bin-arm64/be |
| 10.193.120.46 | BE | 4.19.90-89.11.v2401.ky10.aarch64 | aarch64 | 2.1.11 | /dmdata/doris/apache-doris-2.1.11-bin-arm64/be |
一 具体配置和操作步骤
0 10.193.120.45安装配置FE
官网下载：https://doris.apache.org/download 选择对应的版本和架构。具体步骤略。
查阅Doris官方文档上关于安装配置的前置条件和设置如下，https://doris.apache.org/docs/2.1/install/preparation/cluster-planning
- Disable Transparent Huge Pages
- Ensure Sufficient Virtual Memory Area
- Reset New Connections on Network Overflow
- Increase System's Open File Descriptors Limit
#1 Disable Transparent Huge Pages
cat >> /etc/rc.d/rc.local << EOF
echo madvise > /sys/kernel/mm/transparent_hugepage/enabled
echo madvise > /sys/kernel/mm/transparent_hugepage/defrag
EOF
chmod +x /etc/rc.d/rc.local
#2 Ensure Sufficient Virtual Memory Area
cat >> /etc/sysctl.conf << EOF
vm.max_map_count = 2000000
EOF
# Take effect immediately
sysctl -p
#3 Reset New Connections on Network Overflow
cat >> /etc/sysctl.conf << EOF
net.ipv4.tcp_abort_on_overflow=1
EOF
# Take effect immediately
sysctl -p
#4 Increase System's Open File Descriptors Limit

至此，Doris的FE节点已经配置并启动完成。
1 10.193.120.45安装配置BE
在启动运行BE节点之前，我们先通过访问Doris FE，把本机添加为BE：alter system add backend "10.193.120.45:9050";

至此，看到BE状态已经正常，Alive: true。我们的1个FE+1个BE节点已经配置部署完成。
2 将10.193.20.46作为新的BE添加到Doris cluster
具体需要修改和配置的项目和10.193.20.45服务器配置一样，具体执行过程省略。

这里，我们采用和10.193.20.45服务器上保持一致的路径和版本，以及配置文件内容也保持一致：只修改priority_networks和JAVA_HOME这2个参数。

这里看到新be已经添加成功。但是45机器上的be节点是失败的，具体原因以及分析策略，会在另外一篇进行讨论。
3 设置doris 管理用户root口令
默认情况下，Doris管理账户root的口令是空的，比较不安全，我们需要修改。这里，通过mysql命令行客户端工具，连接之后，进行修改：
#修改Doris Change Doris Cluster Password
SET PASSWORD = PASSWORD('Doris5Xa99@2)4');
MySQL [(none)]> SET PASSWORD = PASSWORD('Doris5Xa99@2)4');
二 小结
我们通过从Doris官网下载ARM64位平台的binary安装包介质文件，在2台信创麒麟V10版本的服务器上，安装配置了1个FE+2个BE的Doris cluster环境。建议在生产环境至少部署3个BE节点，本文中选择2个BE，是基于项目和资源限制，不得已而做出的选择。
