rpm -qa vs yum list installed: Why certain packages can be found with rpm -qa only?
问题现象
Python 2.7.5 是存在的。rpm -qa 可以成功查询，但是 yum list installed却没查到。
[root@CentOS7 centos]# python -V
Python 2.7.5
[root@CentOS7 centos]#
[root@CentOS7 centos]# rpm -qa | grep python-2.7.5
python-2.7.5-58.el7.x86_64
[root@CentOS7 centos]#
[root@CentOS7 centos]# yum list installed | grep python-2.7.5
[root@CentOS7 centos]#
yum list installed 介绍
| the package name | version number | the repository nickname |
|---|---|---|
| audit-libs-python.x86_64 | 2.7.6-3.el7 | @base |
| dbus-python.x86_64 | 1.1.1-9.el7 | installed |
| libselinux-python.x86_64 | 2.5-11.el7 | @base |
| libsemanage-python.x86_64 | 2.5-8.el7 | @base |
| libxml2-python.x86_64 | 2.9.1-6.el7_2.3 | installed |
| newt-python.x86_64 | 0.52.15-4.el7 | installed |
| policycoreutils-python.x86_64 | 2.5-17.1.el7 | @base |
| python.x86_64 | 2.7.5-58.el7 | @base |
| rpm-python.x86_64 | 4.11.3-25.el7 | @base |
yum list installed 查出结果如上分三列显示，可以针对单独某列进行查询，比如
[root@user1 ~]# yum list installed | grep 2.7.5
python.x86_64 2.7.5-58.el7 @base
python-libs.x86_64 2.7.5-58.el7 @base
[root@user1 ~]# yum list installed | grep python.x86_64
audit-libs-python.x86_64 2.7.6-3.el7 @base
dbus-python.x86_64 1.1.1-9.el7 installed
libselinux-python.x86_64 2.5-11.el7 @base
libsemanage-python.x86_64 2.5-8.el7 @base
libxml2-python.x86_64 2.9.1-6.el7_2.3 installed
newt-python.x86_64 0.52.15-4.el7 installed
policycoreutils-python.x86_64 2.5-17.1.el7 @base
python.x86_64 2.7.5-58.el7 @base
rpm-python.x86_64 4.11.3-25.el7 @base
yum list installed | grep python-2.7.5 不支持，需要使用特殊结构查询，这里不展开，可自行查询
rpm -qa 介绍
[root@user1 ~]# rpm -qa | grep 2.7.5
python-libs-2.7.5-58.el7.x86_64
python-2.7.5-58.el7.x86_64
[root@CentOS7 centos]# rpm -qa | grep python-2.7.5
python-2.7.5-58.el7.x86_64
