KingbaseES R3通用机通过es_server部署集群案例

作者:互联网

案例说明:
本案例用于通用机环境生产环境,为了保证系统的安全,禁止启用ssh通讯情况。KingbaseES R3集群在通用机部署 需要通过ssh通讯,本案例通过启用es_server进行通讯,通过shell脚本一键部署KingbaseES R3集群。

数据库版本 :

集群架构:

防火墙需要开放端口:

一、准备部署环境
1、创建kingbase用户

[kingbase@node1 Lin64]$ id kingbase
uid=1001(kingbase) gid=1001(kingbase) groups=1001(kingbase)

2、安装kingbaseES R3通用机软件

[kingbase@node1 Lin64]$ pwd
/opt/Kingbase/ES/V8R3/DeployTools/zip/Lin64

[kingbase@node1 Lin64]$ ls -lh
total 33M
-rw-rw-r--. 1 kingbase kingbase  29M Mar  4  2021 db.zip
-rw-rw-r--. 1 kingbase kingbase 4.3M Mar  4  2021 kingbasecluster.zip

3、创建集群安装目录(所有节点)

[kingbase@node3 kha]$ mkdir -p /home/kingbase/cluster/ha
[kingbase@node1 Lin64]$ mkdir -p /home/kingbase/cluster/ha

4、从软件安装目录上传压缩包到集群目录下并解压
=如下所示一键安装目录,包括集群软件安装包、license文件、部署脚本、部署配置文件=

[kingbase@node1 ha]$ ls -lh
total 33M
drwxrwxr-x 7 kingbase kingbase   65 Mar  4  2021 db
-rw-rw-r-- 1 kingbase kingbase  29M Mar  1 12:08 db.zip
-rwxrwxr-x 1 kingbase kingbase 5.2K Mar  1 12:22 install.conf
drwxrwxr-x 6 kingbase kingbase   48 Mar  4  2021 kingbasecluster
-rw-rw-r-- 1 kingbase kingbase 4.3M Mar  1 12:08 kingbasecluster.zip
-rwxr-x--- 1 kingbase kingbase 3.2K Mar  1 12:21 license.dat
-rwxrwxr-x 1 kingbase kingbase  81K Mar  1 12:21 V8R3_cluster_install.sh

其他节点:(不需要部署脚本和部署配置文件)

[kingbase@node3 ha]$ ls -lh
total 33M
drwxrwxr-x 7 kingbase kingbase   65 Mar  4  2021 db
-rw-rw-r-- 1 kingbase kingbase  29M Mar  1 12:10 db.zip
drwxrwxr-x 6 kingbase kingbase   48 Mar  4  2021 kingbasecluster
-rw-rw-r-- 1 kingbase kingbase 4.3M Mar  1 12:10 kingbasecluster.zip
-rwxr-x--- 1 kingbase kingbase 3.2K Mar  1 12:30 license.dat

二、配置并启动es_server通讯(所有节点)
1、查看es_server脚本文件

[kingbase@node1 ha]$ cd db/bin/
[kingbase@node1 bin]$ ls -lh es_*
-rwxr-xr-x 1 kingbase kingbase  60K Mar  4  2021 es_client
-rwxr-xr-x 1 kingbase kingbase 249K Mar  4  2021 es_server
-rwxr-xr-x 1 kingbase kingbase  148 Mar  4  2021 es_server.conf

2、查看es_server配置文件

[kingbase@node1 bin]$ cat es_server.conf
[Server]
user=kingbase
password=e10adc3949ba59abbe56e057f20f883e
port=8890
connect_timeout=10
health_check_max_retries=2
health_check_retry_delay=5

3、启动es_server

[kingbase@node1 bin]$ ./es_server start &
[1] 12175
[kingbase@node1 bin]$ Usage: ./server -f /path/filename
[Begin start.........]
bind success.
listen success.
[kingbase@node1 bin]$ netstat -an |grep 8890
tcp        0      0 0.0.0.0:8890            0.0.0.0:*               LISTEN

[kingbase@node3 bin]$ ./es_server start &
[1] 4915
[kingbase@node3 bin]$ Usage: ./server -f /path/filename
[Begin start.........]
bind success.
listen success.
[kingbase@node3 bin]$ netstat -an |grep 8890
tcp        0      0 0.0.0.0:8890            0.0.0.0:*               LISTEN

4、测试es_server通讯

[kingbase@node3 bin]$ ./es_client -h 192.168.7.248 -U kingbase -W 123456 -o 'echo $HOSTNAME'
node1
[kingbase@node1 bin]$ ./es_client -h 192.168.7.243 -U kingbase -W 123456 -o 'echo $HOSTNAME'
node3

三、一键部署集群
1、配置部署配置文件install.conf

[kingbase@node1 ha]$ cat install.conf |grep -v ^$|grep -v ^#
on_bmj=1
all_node_ip=(192.168.7.243 192.168.7.248)
cluster_path="/home/kingbase/cluster/ha"
db_package="/home/kingbase/cluster/ha/db.zip"
cluster_package="/home/kingbase/cluster/ha/kingbasecluster.zip"
license_file=(license.dat)
db_user="SYSTEM"                 # the user name of database
db_password="123456"             # the password of database, since the R3 has a special feature that password cannot be stored in clear text, please delete the password after the cluster deployment is complete.
db_port="54321"                  # the port of database, defaults is 54321
trust_ip="192.168.7.1"
db_vip="192.168.7.240"
cluster_vip="192.168.7.241"
net_device=(enp0s3 enp0s3)
kb_data="/home/kingbase/cluster/ha/db/data"
ipaddr_path="/sbin"
arping_path="/opt/Kingbase/ES/V8R3/Server/bin"
super_user="root"
cluster_user="kingbase"
wd_deadtime="30"                 # cluster heartbeats timeout, unit: seconds
check_retries="6"                # number of detection retries in case of database failure
check_delay="10"                 # detection retry interval in case of database failure
connect_timeout="10000"          # timeout value in milliseconds before giving up to connect to backend
auto_primary_recovery="0"       # automatic recovery parameter of cluster primary host, default value is 0

2、需要修改配置脚本V8R3_cluster_install.sh

1)修改部署脚本中集群安装目录(默认bmj使用:"/opt/Kingbase/ES/V8")

function read_conf()
112 {
113     [ "${install_conf}"x = ""x ] && install_conf="${shell_folder}/install.conf"
115     [ ! -e $install_conf ] && echo "[ERROR] $install_conf is not exits" && exit 1
116     if [ -f $install_conf ]
117     then
118         source $install_conf
119     fi
121     [ "${on_bmj}"x = ""x ] && on_bmj=0
122     #[ $on_bmj -eq 1 ] && cluster_path="/opt/Kingbase/ES/V8"
123     [ $on_bmj -eq 1 ] && cluster_path="/home/kingbase/cluster/ha"
124     [ $on_bmj -eq 1 ] && license_path=(${cluster_path}/license.dat)

2)修改部署脚本中集群部署路径

if [ $on_bmj -eq 0 ]
then
kb_bin="$cluster_path/Server/bin"
kb_etc="$cluster_path/Server/etc"
kb_lib="$cluster_path/Server/lib"
cluster_etc="$cluster_path/Cluster/etc"
cluster_bin="$cluster_path/Cluster/bin"
cluster_lib="$cluster_path/Cluster/lib"
else
kb_bin="$cluster_path/db/bin"
kb_etc="$cluster_path/db/etc"
kb_lib="$cluster_path/db/lib"
cluster_etc="$cluster_path/kingbasecluster/etc"
cluster_bin="$cluster_path/kingbasecluster/bin"
cluster_lib="$cluster_path/kingbasecluster/lib"
fi
kb_archive="$cluster_path/archivedir"
log_path="$cluster_path/log"

3、开始部署

[root@node1 ha]# ./V8R3_cluster_install.sh
[CONFIG_CHECK] file format is correct ... OK
[CONFIG_CHECK] file format is correct ... OK

.......

四、部署完成测试

1、查看流复制信息

1)查看主备库数据库服务(如下所示,主备库数据库服务启动正常,如未启动可以用sys_ctl手工启动)

主库:
[kingbase@node3 db]$ ps -ef |grep kingbase
kingbase  4915  2980  0 12:30 pts/0    00:00:00 ./es_server start
kingbase  7515     1  0 13:00 pts/0    00:00:00 /home/kingbase/cluster/ha/db/bin/kingbase -D /home/kingbase/cluster/ha/db/data
kingbase  7516  7515  0 13:00 ?        00:00:00 kingbase: logger process

kingbase  7520  7515  0 13:00 ?        00:00:00 kingbase: wal writer process
kingbase  7521  7515  0 13:00 ?        00:00:00 kingbase: autovacuum launcher process
kingbase  7522  7515  0 13:00 ?        00:00:00 kingbase: archiver process   last was 000000010000000000000002
kingbase  7523  7515  0 13:00 ?        00:00:00 kingbase: stats collector process
kingbase  7524  7515  0 13:00 ?        00:00:00 kingbase: bgworker: syslogical supervisor

备库:
[kingbase@node1 bin]$ ps -ef |grep kingbase
kingbase 12175     1  0 12:28 pts/0    00:00:00 ./es_server start
kingbase 27927     1  0 13:09 pts/0    00:00:00 /home/kingbase/cluster/ha/db/bin/kingbase -D /home/kingbase/cluster/ha/db/data
kingbase 27928 27927  0 13:09 ?        00:00:00 kingbase: logger process
kingbase 27929 27927  0 13:09 ?        00:00:00 kingbase: startup process   recovering 000000010000000000000003
kingbase 27934 27927  0 13:09 ?        00:00:00 kingbase: checkpointer process
kingbase 27935 27927  0 13:09 ?        00:00:00 kingbase: writer process
kingbase 27936 27927  0 13:09 ?        00:00:00 kingbase: stats collector process
kingbase 27937 27927  0 13:09 ?        00:00:00 kingbase: wal receiver process

2)查看路复制状态

[kingbase@node3 bin]$ ./ksql -U SYSTEM -W 123456 TEST
ksql (V008R003C002B0270)
Type "help" for help.
TEST=# select * from sys_stat_replication;
PID  | USESYSID | USENAME | APPLICATION_NAME |  CLIENT_ADDR  | CLIENT_HOSTNAME | CLIENT_PORT |         BACKEND_START         | BACKEND_XMIN |

------+----------+---------+------------------+---------------+-----------------+-------------+-------------------------------+--------------+---
7839 |       10 | SYSTEM  | node2            | 192.168.7.248 |                 |       11998 | 2021-03-01 13:10:15.273987+08 |              | st
reaming | 0/3000220     | 0/3000220      | 0/3000220      | 0/3000220       |             2 | sync
(1 row)

2、启动集群服务
=默认通用机环境kingbase_monitor.sh启动集群是通过ssh通讯,所以在部署完成后,仍然无法通过kingbase_monitor.sh启动集群=
**1)kingbase_monitor.sh **

2)手工启动kingbasecluster服务(root用户,所有节点)

[root@node3 .ssh]# cd /home/kingbase/cluster/ha/kingbasecluster/bin
[root@node3 bin]# ./kingbasecluster -n > cluster.log 2>&1 &
[1] 9437

[root@node3 bin]# ps -ef |grep kingbase
kingbase  4915     1  0 12:30 pts/0    00:00:00 ./es_server start
kingbase  7515     1  0 13:00 pts/0    00:00:00 /home/kingbase/cluster/ha/db/bin/kingbase -D /home/kingbase/cluster/ha/db/data
kingbase  7516  7515  0 13:00 ?        00:00:00 kingbase: logger process

3)集群信息查看

[root@node3 bin]# ./ksql -U SYSTEM -W 123456 TEST -p 9999
ksql (V008R003C002B0270)
Type "help" for help.

(1 row)

=如以上所示,可以通过手工启动kingbasecluster集群服务及数据库服务完成集群的启动=

五、部署kingbase_monitor.sh一键管理集群

1、安装R3专用机版本数据库服务

2、如下所示kingbase_monitor.sh(专用机通过es_server通讯)

3、将专用机安装目录下sh脚本拷贝到所有节点

[root@node1 bin]# pwd
/opt/Kingbase/ES/V8/Server/bin 
![](https://www.icode9.com/i/l/?n=22&i=blog/2420370/202201/2420370-20220121144827172-868786745.png)

[root@node1 bin]# cp change_vip.sh  /home/kingbase/cluster/ha/db/bin
[root@node1 bin]# cp network_rewind.sh  /home/kingbase/cluster/ha/db/bin
[root@node1 bin]# cp kingbase_monitor.sh  /home/kingbase/cluster/ha/db/bin
[root@node1 bin]# cp kingbase_promote.sh  /home/kingbase/cluster/ha/db/bin

=注意:需要将all_mornitor.sh 拷贝到db/bin 和kingbasecluster/bin下=

[root@node1 bin]# cp all_monitor.sh  /home/kingbase/cluster/ha/db/bin
[root@node1 bin]# cp all_monitor.sh  /home/kingbase/cluster/ha/kingbasecluster/bin

六、总结
对于通用机使用es_server部署成本较高,需要修改部署脚本及集群启动脚本,建议尽量使用ssh部署。
