+
+参考一下链接进行opengauss3.0.0版本的编译安装
+
+ [(52条消息) 源码编译安装opengauss 3.0版本_baiwaqingqiang的博客-CSDN博客](https://blog.csdn.net/baiwaqingqiang/article/details/125084077?spm=1001.2014.3001.5501)
+
+
+显示编译完成后设置环境变量
+
+```java
+vim ~/.bashrc
+```
+
+在里面添加一下环境变量
+
+```java
+export CODE_BASE=/opt/openGauss-server #openGauss-server的路径
+export GAUSSHOME=$CODE_BASE/mppdb_temp_install/
+export LD_LIBRARY_PATH=$GAUSSHOME/lib::$LD_LIBRARY_PATH
+export PATH=$GAUSSHOME/bin:$PATH
+```
+
+source一下使其生效
+
+```java
+source ~/.bashrc
+```
+
+如果遇到gs_ctl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory问题，证明是设置环境变量问题，可以用export命令查看一下是否又ld_library_path环境变量，没有的话将其设置
+
+紧接着建立数据日志，初始化数据库集群和启动数据库
+
+```java
+cd /opt
+mkdir db_data
+gs_initdb ‐D /opt/db_data/ ‐‐nodename=test 
+gs_ctl start ‐D /opt/db_data/ ‐Z single_node ‐l logfile
+gsql postgres
+```
+
+至此数据库连接成功。
+
+
+**克隆插件仓库**
+
+```java
+git clone https://gitee.com/dadagum/Plugin.git -b compatible_time_type
+```
+
+克隆下来的文件结构是这样子的，如图一。图二是dolphin文件夹移动的目标位置。

+&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;图一&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;图二
+
+&nbsp;然后把其中的dolphin文件移动到opengauss中的contrib
+
+```java
+mv /opt/Plugin/contrib/dolphin /opt/openGauss-server/contrib/
+```
+
+进入server中的dolphin文件夹，执行make -sj &amp;&amp; make install -sj，就可以将dolphin插件导入opengauss。
+
+在数据库中验证，把下图的create extension b_sql_plugin改为create extension dolphin。看到create extension反馈后表示成功。
