GoldenDB 快速安装分布式集群
2026-10-10 09:24 圣彼得堡的村长 阅读(10) 评论(0) 收藏 举报GoldenDB 快速安装分布式集群
之前的文章里介绍了通过配置 install_senior.ini 文件来标准安装 GoldenDB 集中式集群，前提是需要我们了解 GoldenDB 的集群架构以及参数意义，这对初学者来说不太友好。好在官方提供了三种安装模式，这次我们介绍一下通过配置 install_fast.ini 文件，快速安装分布式集群。
- 快速安装: 单机房(install_fast.ini)
- 自定义安装: 单机房(install_advance.ini)
- 标准安装: 多机房(install_senior.ini)
1. 安装规划
跟标准安装不同，快速安装无需规划每个节点安装的组件及角色。
| 主机名 | IP 地址 | 配置大小 |
|---|---|---|
| golden1 | 192.168.182.41 | 12C/24G |
| golden2 | 192.168.182.42 | 8C/16G |
| golden3 | 192.168.182.43 | 8C/16G |
2. 基础环境准备
2.1 配置主机名
每台机器各自执行：
hostnamectl set-hostname golden1
hostnamectl set-hostname golden2
hostnamectl set-hostname golden3
2.2 关闭和禁用防火墙及 NetworkManager
systemctl stop NetworkManager firewalld.service
systemctl disable NetworkManager firewalld.service
2.3 配置 yum 源
sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
2.4 关闭 Selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
2.5 设置时区
timedatectl | grep "Time zone"
sudo timedatectl set-timezone Asia/Shanghai
date
2.6 禁用透明大页和 NUMA
#禁用透明大页
sed -i 's/GRUB_CMDLINE_LINUX="/GRUB_CMDLINE_LINUX="transparent_hugepage=never /g' /etc/default/grub
#禁用NUMA（ Intel 环境建议关闭）， Hygon、AMD、ARM 环境中，建议打开 NUMA
sed -i 's/GRUB_CMDLINE_LINUX="/GRUB_CMDLINE_LINUX="numa=off /g' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
#重启生效
reboot
cat /sys/kernel/mm/transparent_hugepage/enabled
dmesg | grep -i numa
2.7 修改 limits 参数
cat >> /etc/security/limits.conf <<EOF
* soft nofile 655350
* hard nofile 655350
* soft stack unlimited
* hard stack unlimited
* soft nproc 655360
* hard nproc 655360
* soft core unlimited
* hard core unlimited
EOF
2.8 安装 python2 及依赖
yum install -y python2 python2-devel numactl perl-Time-HiRes bind-chroot java-2.8.0-openjdk gcc unixODBC bind-libs tar expect
# 安装 Python 开发扩展包和工具
yum install -y python-devel python-setuptools python-pip gcc
3. 安装准备
3.1 上传安装包
上传安装包到 golden1 节点 /root/ 目录，并解压到 /home 目录。
[root@golden1 home]# ll
总用量 2
drwxr-xr-x 13 root root 4096 9月 14 17:57 ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12
-rw-r--r-- 1 root root 0 9月 14 15:07 ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12.zip
解压完后，在相同目录 touch 一个与文件夹同名的 zip 包，避免每次解压浪费时间。
3.2 安装 PyMySQL
安装包附带 PyMySQL-master.tar.gz ，在节点1 安装 PyMySQL。
[root@golden1 install]# pwd
/home/ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12/oneKeyInstallUpdate/install
[root@golden1 install]# find ./ -name PyMySQL*
./prepare_env/PyMySQL-master.tar.gz
[root@golden1 install]# tar -zxvf ./prepare_env/PyMySQL-master.tar.gz
[root@golden1 install]# cd PyMySQL-master/
[root@golden1 PyMySQL-master]# python setup.py install
3.3 安装 kazoo
安装包附带 kazoo-2.6.1.tar.gz 包，在节点1 安装 kazoo。
[root@golden1 install]# find ./ -name "*kazoo*"
./prepare_env/kazoo-2.6.1.tar.gz
[root@golden1 install]# tar -zxvf ./prepare_env/kazoo-2.6.1.tar.gz
[root@golden1 install]# cd kazoo-2.6.1/
[root@golden1 kazoo-2.6.1]# python setup.py install
3.4 配置 install_fast.ini 文件
修改的内容如下：
- 准备部署
GoldenDB集群的机器 IP 地址； - 安装的 root 用户及密码
GoldenDB安装时所涉及的密码，统一配置成了 Gdcp@2026
# 适用快速体验安装, 单区域，单管理节点或ZK环境，多分片集群，服务器资源最小8C16G
[general]
# 安装机器IP, 填写一个或多个，以逗号分割,首IP请填写本机IP
# IP支持ipv4或ipv6格式
IP=192.168.182.41,192.168.182.42,192.168.182.43

insight_cgroup_limit=2C6G
3.5 调整等待间隔
在第 12 步安装组件，初始化数据库时，默认等待 40 次，每次 30 秒，如果由于磁盘性能不够等因素导致超过了 1200 秒，安装主程序就会报错，但是数据库仍可始化成功，可以将时间间隔或者等待次数调大一些，避免主程序报错终止。
vim /ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12/oneKeyInstallUpdate/install/global_args.py
# 安装组件超时时间计算方式为 MAX_INTERVAL_COUNT*SLEEP_TIME
# 默认 1200秒=20min
MAX_INTERVAL_COUNT = 40 # 单位：次数
INTERVAL_TIME = 60 # 单位：秒
4. 安装过程
4.1 执行安装
执行如下命令开始安装：
sh setup.sh -a "" "/home/ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12.zip" "/home/ZXCLOUD-GoldenDB-ALL-RHV6.1.03.12/oneKeyInstallUpdate/install/config/install_fast.ini"
如遇到报错，使用如下命令清空环境，重新安装：
-- 杀掉相关进程
pkill -9 -u insight 2>/dev/null;
pkill -9 -u zxgtm1 2>/dev/null;
pkill -9 -u zxgtm2 2>/dev/null;
pkill -9 -u zxgtm3 2>/dev/null;
pkill -9 -u zxdb1 2>/dev/null;
pkill -9 -u zxdb2 2>/dev/null;
pkill -9 -u zxdb3 2>/dev/null;
pkill -9 -u zxdbproxy1 2>/dev/null;
pkill -9 -u zxdbproxy2 2>/dev/null;
pkill -9 -u zxmanager 2>/dev/null;
pkill -9 -u zxload1 2>/dev/null;
-- 清理 insight 的 agent
ps -ef |grep insight | grep -v grep | awk '{print $2}' | xargs kill -9
-- 删除已安装的用户
for u in $(cat /etc/passwd | awk -F: '{print $1}' | grep -E "insight|zxgtm|zxdb|zxdbproxy|zxgdbcheck|zxmanager|zxload");
do userdel -r "$u" 2>/dev/null; done;
-- 删除用户组
groupdel goldendb 2>/dev/null;
4.2 安装过程
安装程序自动根据 install_fast.ini 文件中的信息生成 install_senior.ini 文件。自动规划的组件如下：
- DB：划分了两个分片组，每个分片组为一主两备的同步集群，但是没有安装 sys 租户的集群。
- DBProxy：部署在 golden1 和 golden2 节点；
- insight：部署在 golden1 节点；
- GTM：部署在golden1 和 golden2 节点，一主一备；

安装过程和标准安装类似，安装完所有组件后，会启动所有组件，并组建集群。
5. 部署验证
5.1 insight 页面查看
打开 insight 所在的服务器 IP:8444 ，输入 admin/ Insight@2020 登录，查看集群信息。
发现目前存在两个分片组，每个分片组由一主两备的 mysqld 实例组成；两个 DBProxy 以及两个 GTM（互为主备）。我们创建一张 range 分区表，并插入数据：
-- 通过 DBProxy 登录
mysql -h 192.168.182.41 -P 8880 -u dbproxy -p'Gdcp@2026' test
goldendb_client> CREATE TABLE t_order_range (
order_id INT NOT NULL,
user_id INT NOT NULL,
amount DECIMAL(10, 2) DEFAULT NULL,
create_time DATETIME DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (order_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin
DISTRIBUTED BY RANGE (order_id) (
g1 VALUES LESS THAN (5000),
g2 VALUES LESS THAN MAXVALUE
);
goldendb_client> CALL p_batch_insert_data(1, 40000);
goldendb_client> SELECT 'g1_count' as shard, COUNT(*) FROM t_order_range STORAGEDB g1;
+----------+----------+
| SHARD | COUNT(*) |
+----------+----------+
| g1_count | 4999 |
+----------+----------+
1 row in set (0.16 sec)
goldendb_client> SELECT 'g2_count' as shard, COUNT(*) FROM t_order_range STORAGEDB g2;
+----------+----------+
| SHARD | COUNT(*) |
+----------+----------+
| g2_count | 35001 |
+----------+----------+
1 row in set (0.17 sec)
5.2 新增分片
输入分片 ID 为 4，数据节点数为 3（一共包含 3 个 MySQL 底层实例），响应数为 1（即 response_num=1 ，代表在执行分布式分布式两阶段提交或主备同步时，只要有 1 个备节点成功响应，该 Team 就会向 Proxy 汇报成功，允许事务提交。）
新增的数据分片会在每个节点再部署一个实例。
分片 4 新建成功： 
现在 golden1 和 golden2 两个节点分别存在 4 个 mysqld 实例，golden3 存在 3 个 mysqld 实例。
至此，通过配置 install_fast.ini 文件快速安装分布式集群成功了。下一期，我们演示一下 GoldenDB 的分区表操作。
