幾種查看linux版本信息的方法：
- uname -a
- cat /proc/version
- cat /etc/issue
- lsb_release -a
-
登錄到服務(wù)器執(zhí)行 lsb_release -a ，即可列出所有版本信息，例如：
這個(gè)命令適用于所有的linux，包括Redhat、SuSE、Debian等發(fā)行版。- [root@3.5.5Biz-46 ~]# lsb_release -a
- LSB Version: 1.3
- Distributor ID: RedHatEnterpriseAS
- Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 1)
- Release: 4
- Codename: NahantUpdate1
- [root@3.5.5Biz-46 ~]#
-
登錄到linux執(zhí)行cat /etc/redhat-release ，例如如下：
這種方式下可以直接看到具體的版本號(hào)，比如 AS4 Update 1- [root@3.5.5Biz-46 ~]# cat /etc/redhat-release
- Red Hat Enterprise Linux AS release 4 (Nahant Update 1)
- [root@3.5.5Biz-46 ~]#
-
登錄到linux執(zhí)行rpm -q redhat-release ，例如如下
這種方式下可看到一個(gè)所謂的release號(hào)，比如上邊的例子是2.4- [root@3.5.5Biz-46 ~]# rpm -q redhat-release
- redhat-release-4AS-2.4
- [root@3.5.5Biz-46 ~]#
這個(gè)release號(hào)和實(shí)際的版本之間存在一定的對(duì)應(yīng)關(guān)系，如下：
注意：第2、3兩種方法只對(duì)Redhat Linux有效- redhat-release-3AS-1 -> Redhat Enterprise Linux AS 3
- redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4
- redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4
- redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1
- redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2
- redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3
- redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4
