一、问题描述：目前找不到任何关于opengauuss Datakit安装部署的文档，自己来尝试踩坑。
DataKit是一个以资源（物理机，数据库）为底座的开发运维工具，将上层的开发运维工具插件化，各插件之间相互独立，方便用户按需引入。各插件围绕DataKit的资源中心进行扩展开，完成数据库的运维，监控，迁移，开发，建模等复杂的操作。
Datakit安装部署在服务器上，是一个自动化运维的平台。可以部署不同类型的插件来实现不同的功能，是跟随opengauss5.0发布的新软件，也可以用来监控小于5.0的opengauss版本
二、环境准备：
Datakit官方文档：https://docs.opengauss.org/zh/docs/5.0.0/docs/ToolandCommandReference/DataKit.html
DataKit使用文档和开发文档：https://gitee.com/opengauss/openGauss-workbench/tree/master/openGauss-visualtool/doc
openGauss-workbench下载链接：https://gitee.com/opengauss/openGauss-workbench.git
Datakit下载链接：https://opengauss.org/zh/download/
JDK下载链接：https://www.oracle.com/in/java/technologies/javase/jdk11-archive-downloads.html#license-lightbox
linux操作系统的jdk版本要与datakit打的jar包jdk版本保持一致，要不然通过不了
三、安装部署
部署环境：redhat7，opengauss3.0.3，Datakit5.0
1.上传压缩包
# 此时如果没有/ops/server/openGauss-visualtool目录，可以临时手动创建，也可以把这一步在初始化环境中进行解压
[root@test01 tmp]# tar -xvf Datakit-5.0.0.tar.gz -C /ops/server/openGauss-visualtool
jdk手动安装
workbench-master有启动和初始化的脚本可以拿来用
datakit除了visualtool-main.jar 放在/ops/server/openGauss-visualtool目录中，其余几个打包好的插件需要放在/ops/server/openGauss-visualtool/visualtool-plugin/ 目录中
2.更新jdk版本，如果需要
# 检查
rpm -qa | grep java rpm -qa | grep jdk
# 卸载 rpm -qa | grep java | xargs rpm -e --nodeps rpm -qa | grep jdk | xargs rpm -e --nodeps
# 安装
rpm -ivh jdk-11.0.17_linux-x64_bin.rpm
# 验证
[root@test01 tmp]# java -version
java version "11.0.17" 2022-10-18 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.17+10-LTS-269)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.17+10-LTS-269, mixed mode)
3.创建远程用户
# 创建用户
openGauss=# CREATE USER jack WITH MONADMIN password "xxxxxxxx"; openGauss=# alter user jack sysadmin;
# 写入pg_hba.conf文件
[omm@test01 ~]$ gs_guc set -N all -I all -h "host all jack 192.168.1.0/24 sha256"
4.编辑安装和启动脚本
安装脚本在\openGauss-workbench-master\openGauss-workbench-master\openGauss-visualtool中
使用安装脚本初始化环境，或者使用https://docs.opengauss.org/zh/docs/5.0.0/docs/ToolandCommandReference/DataKit.html文档中初始化环境，安装脚本需要修改一下。如果脚本执行不顺畅，也可以手动跑脚本中的内容，保障目录正常，以及加密文件生成
# 创建ops用户
useradd -m ops
vim install.sh
#!/usr/bin/env bash echo "begin install..." #sh ./uninstall.sh read -p "Do you want to automatically install dependencies (JDK, maven, node) ? (Press y|Y for Yes, any other key for No). " install_depency if [ "$install_depency" = "Y" -o "$install_depency" = "y" ]; then #sh ./install-depency.sh else echo "Please install the dependencies required by the system by yourself, including openjdk (11), maven (3), and node (16.15.1)." exit 1 fi read -p "Please enter the host of openGauss, Please ensure that the current host IP is in the whitelist of openGauss: " host if [ ! -n "$host" ]; then echo "Host cannot be empty." exit 1 fi read -p "Please enter the port of openGauss.: " port if [ ! -n "$port" ]; then echo "Port cannot be empty." exit 1 fi read -p "Please enter the database of openGauss.: " database if [ ! -n "$database" ]; then echo "Database cannot be empty." exit 1 fi read -p "Please enter the username of openGauss.: " username if [ ! -n "$username" ]; then echo "Username cannot be empty." exit 1 fi stty -echo read -p "Please enter the password of openGauss.: " password if [ ! -n "$password" ]; then echo "Password cannot be empty." exit 1 fi stty echo echo "host: $host, port: $port username: $username database: $database" cp config/application-temp.yml config/application-cus.yml sed -i "23s/ip:port/$host:$port/" config/application-cus.yml sed -i "23s/database/$database/" config/application-cus.yml sed -i "24s/dbuser/$username/" config/application-cus.yml sed -i "25s/dbpassword/$password/" config/application-cus.yml #mvn clean install -P prod -Dmaven.test.skip=true mkdir -p /ops/server/openGauss-visualtool/ mkdir -p /ops/files/ mkdir -p /ops/server/openGauss-visualtool/logs/ mkdir -p /ops/server/openGauss-visualtool/config/ mkdir -p /ops/ssl/ if [ ! -f "/ops/ssl/keystore.p12" ];then keytool -genkey -noprompt \ -dname "CN=opengauss, OU=opengauss, O=opengauss, L=Beijing, S=Beijing, C=CN"\ -alias opengauss\ -storetype PKCS12 \ -keyalg RSA \ -keysize 2048 \ -keystore /ops/ssl/keystore.p12 \ -validity 3650 \ -storepass 123456 fi echo "SSL is enabled, you can replace the keystore file at /ops/ssl/ folder and config the ssl options at file /ops/server/openGauss-visualtool/config/application-cus.yml" touch /ops/server/openGauss-visualtool/logs/visualtool-main.out cp visualtool-api/target/visualtool-main.jar /ops/server/openGauss-visualtool/ mv config/application-cus.yml /ops/server/openGauss-visualtool/config/ chown -R ops:ops /ops echo "end install"
编辑启动脚本
#!/usr/bin/env bash SERVER_HOME=/ops/server/openGauss-visualtool cd $SERVER_HOME API_NAME=visualtool-main JAR_NAME=$SERVER_HOME/$API_NAME\.jar LOG=$SERVER_HOME/logs/$API_NAME\.out PID=$SERVER_HOME/$API_NAME\.pid usage() { echo "Usage: sh server.sh [start|stop|restart|status]" exit 1 } is_exist(){ pid=`ps -ef|grep $JAR_NAME|grep -v grep|awk '{print $2}' ` if [ -z "${pid}" ]; then return 1 else return 0 fi } start(){ is_exist if [ $? -eq "0" ]; then echo ">>> ${JAR_NAME} is already running PID=${pid} <<<" else echo '' > $LOG nohup java -Xms2048m -Xmx4096m -jar $JAR_NAME --spring.profiles.active=cus >$LOG 2>&1 & echo $! > $PID echo ">>> start $JAR_NAME successed PID=$! <<<" fi } stop(){ pidf=$(cat $PID) echo ">>> ${API_NAME} PID = $pidf begin kill $pidf <<<" kill $pidf rm -rf $PID sleep 2 is_exist if [ $? -eq "0" ]; then echo ">>> ${API_NAME} 2 PID = $pid begin kill -9 $pid <<<" kill -9 $pid sleep 2 echo ">>> $JAR_NAME process stopped <<<" else echo ">>> ${JAR_NAME} is not running <<<" fi } status(){ is_exist if [ $? -eq "0" ]; then echo ">>> ${JAR_NAME} is running PID is ${pid} <<<" else echo ">>> ${JAR_NAME} is not running <<<" fi } restart(){ stop start } case "$1" in "start") start ;; "stop") stop ;; "status") status ;; "restart") restart ;; *) usage ;; esac exit 0 }
5.初始化环境
[root@test01 openGauss-visualtool]# mv application-temp.yml ./config/ [root@test01 openGauss-visualtool]# ./install.sh begin install... sh: ./uninstall.sh: No such file or directory Do you want to automatically install dependencies (JDK, maven, node) ? (Press y|Y for Yes, any other key for No). Y sh: ./install-depency.sh: No such file or directory Please enter the host of openGauss, Please ensure that the current host IP is in the whitelist of openGauss: 10.83.239.211 Please enter the port of openGauss.: 26000 Please enter the database of openGauss.: postgres Please enter the username of openGauss.: jack Please enter the password of openGauss.: host: 192.168.163.21, port: 26000 username: jack database: postgres SSL is enabled, you can replace the keystore file at /ops/ssl/ folder and config the ssl options at file /ops/server/openGauss-visualtool/config/application-cus.yml cp: cannot stat ‘visualtool-api/target/visualtool-main.jar’: No such file or directory mv: ‘config/application-cus.yml’ and ‘/ops/server/openGauss-visualtool/config/application-cus.yml’ are the same file end install
[root@hktestmysqldb01 openGauss-visualtool]# ll config/ total 8 -rw------- 1 ops ops 873 Apr 11 16:42 application-cus.yml -rw-r--r-- 1 ops ops 865 Mar 28 20:47 application-temp.yml [root@hktestmysqldb01 openGauss-visualtool]# pwd /ops/server/openGauss-visualtool
6. 启动服务
# 把模板移动到插件目录下。也可以后期启动好平台后手动补入插件 [ops@test01 openGauss-visualtool]$ mkdir -p /ops/server/openGauss-visualtool/visualtool-plugin [ops@test01 openGauss-visualtool]$ mv base-ops-5.0.0-repackage.jar ./visualtool-plugin/ [ops@test01 openGauss-visualtool]$ mv data-migration-5.0.0-repackage.jar ./visualtool-plugin/ [ops@test01 openGauss-visualtool]$ mv observability-instance-5.0.0-repackage.jar ./visualtool-plugin/ [ops@test01 openGauss-visualtool]$ mv observability-log-search-5.0.0-repackage.jar ./visualtool-plugin/ [ops@test01 openGauss-visualtool]$ mv observability-sql-diagnosis-5.0.0-repackage.jar ./visualtool-plugin/ [ops@test01 openGauss-visualtool]$ mv webds-plugin-5.0.0-repackage.jar ./visualtool-plugin/ # ./server.sh start/stop/restart [ops@test01 openGauss-visualtool]$ ./server.sh restart >>> visualtool-main PID = 45148 begin kill 45148 <<< >>> /ops/server/openGauss-visualtool/visualtool-main.jar is not running <<< >>> start /ops/server/openGauss-visualtool/visualtool-main.jar successed PID=46530 <<<
7.检查是否启动成功
/ops/server/openGauss-visualtool/logs/visualtool-main.out 会记录实时日志
[root@test01 ~]# netstat -ntpl | grep 9494 tcp 0 0 0.0.0.0:9494 0.0.0.0:* LISTEN 46530/java
前台访问链接：https://192.168.163.21:9494/
插件管理，如果没有做第6部在服务器上移动插件，也可以在前台手动导入一次
