MogDB 安装解压错误：cannot run bzip2: No such file or directory

问题症状

MogDB 安装时，涉及两个步骤解压，第一步解压缩 tar 包：

[root@enmotech ~]# tar -xvf MogDB-2.1.1-CentOS-x86_64.tar

upgrade_sql.tar.gz

MogDB-2.1.1-CentOS-64bit.sha256

MogDB-2.1.1-CentOS-64bit.tar.bz2

MogDB-2.1.1-CentOS-64bit-Libpq.tar.gz

MogDB-2.1.1-CentOS-64bit-om.sha256

MogDB-2.1.1-CentOS-64bit-om.tar.gz

MogDB-2.1.1-CentOS-64bit-tools.tar.gz

upgrade_sql.sha256

第二步，解压缩 bz2 文件包，在这一步骤遇到错误，提示 bzip2 不能执行，这是因为操作系统上没有安装 bz2 解压缩工具：

[root@enmotech MogDB]# tar -jxf MogDB-2.1.1-CentOS-64bit.tar.bz2

tar (child): bzip2: Cannot exec: No such file or directory

tar (child): Error is not recoverable: exiting now

tar: Child returned status 2

tar: Error is not recoverable: exiting now

问题分析

手工安装，如果配置了 yum 源，通过命令

yum -y install bzip2

来安装 bzip2 工具。

[root@enmotech MogDB]# yum -y install bzip2
