[omm@mogdb-kernel-0002 ~]$ gs_install -X /opt/software/opengauss1/clusterconfig.xml --gsinit-parameter="--locale=en_US.UTF-8" --gsinit-parameter="--encoding=UTF-8"
-bash: gs_install：未找到命令
报错原因：
因为环境变量里的 GAUSSHOME 值为/opt/software/opengauss，但是执行安装时，命令所指定的路径为 opengauss1，完整命令为：gs_install -X /opt/software/opengauss1/clusterconfig.xml --gsinit-parameter="--locale=en_US.UTF-8" --gsinit-parameter="--encoding=UTF-8"。出现了不一致，就容易导致此种错误。
解决办法：
删除环境变量中的 GAUSSHOME 配置后，重新执行安装命令 gs_install -X /opt/software/opengauss1/clusterconfig.xml --gsinit-parameter="--locale=en_US.UTF-8" --gsinit-parameter="--encoding=UTF-8"即可解决问题。
