怎样查看Linux系统的版本.docx

怎样查看Linux系统的版本Linux系统版本的命令一、查看内核版本命令：1)[root@SOR_SYS~]#cat/proc/versionLinuxversion2.6.18-238.el5([e-mail])(gccversion4.1.220080704(RedHat4.1.2-50))#1SMPSunDec1914:22:44EST2010[root@SOR_SYS~]#2)[root@SOR_SYS~]#uname-r2.6.18-238.el53)[root@SOR_SYS~]#uname-aLinuxSOR_SYS.99bill.com2.6.18-238.el5#1SMPSunDec1914:22:44EST2010x86_64x86_64x86_64GNU/Linux[root@SOR_SYS~]#二、查看linux版本：1)登录到服务器执行lsb_release-a,即可列出所有版本信息,例如:[root@SOR_SYS~]#lsb_release-aLSBVersion::core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarchDistributorID:RedHatEnterpriseASDescription:RedHatEnterpriseLinuxASrelease4(NahantUpdate4)Release:4Codename:NahantUpdate4[root@SOR_SYS~]#注:这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。2)登录到linux执行cat/etc/issue,例如如下:[root@SOR_SYS~]#cat/etc/issueRedHatEnterpriseLinuxServerrelease5.6(Tikanga)Kernel\ronan\m[root@SOR_SYS~]#3)登录到linux执行cat/etc/redhat-release,例如如下:[root@SOR_SYS~]#cat/etc/redhat-releaseRedHatEnterpriseLinuxASrelease4(NahantUpdate4)[root@SOR_SYS~]#注:这种方式下可以直接看到具体的版本号，比如AS4Update14)登录到linux执行rpm-qredhat-release,例如如下:[root@SOR_SYS~]#rpm-qredhat-releaseredhat-release-5Server-5.6.0.3[root@SOR_SYS~]#注:这种方式下可看到一个所谓的release号，比如上边的例子是5这个release号和实际的版本之间存在一定的对应关系，如下：redhat-release-3AS-1->RedhatEnterpriseLinuxAS3redhat-release-3AS-7.4->RedhatEnterpriseLinuxAS3Update4redhat-release-4AS-2->RedhatEnterpriseLinuxAS4redhat-release-4AS-2.4->RedhatEnterpriseLinuxAS4Update1redhat-release-4AS-3->RedhatEnterpriseLinuxAS4Update2redhat-release-4AS-4.1->RedhatEnterpriseLinuxAS4Update3redhat-release-4AS-5.5->RedhatEnterpriseLinuxAS4Update4另:第3)、4)两种方法只对RedhatLinux有效5)[root@SOR_SYS~]#file/bin/bash/bin/bash:ELF64-bitLSBexecutable,AMDx86-64,version1(SYSV),forGNU/Linux2.6.9,dynamicallylinked(usessharedlibs),forGNU/Linux2.6.9,stripped[root@SOR_SYS~]#6)[root@SOR_SYS~]#file/bin/cat/bin/cat:ELF64-bitLSBexecutable,AMDx86-64,version1(SYSV),forGNU/Linux2.6.9,dynamic
