fio效能測試手記

FIO安裝測試範例

[root@supermic2 ~]#

[root@supermic2 ~]# mkdir fio

[root@supermic2 ~]# cd fio/

[root@supermic2 fio]# wget ftp://195.220.108.108/linux/dag/redhat/el7/en/x86_64/dag/RPMS/fio-2.1.10-1.el7.rf.x86_64.rpm

[root@supermic2 fio]# rpm -ivh fio-2.1.10-1.el7.rf.x86_64.rpm

warning: fio-2.1.10-1.el7.rf.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

error: Failed dependencies:

        libc.so.6(GLIBC_2.14)(64bit) is needed by fio-2.1.10-1.el7.rf.x86_64

        libm.so.6(GLIBC_2.15)(64bit) is needed by fio-2.1.10-1.el7.rf.x86_64

請勿跟我一樣犯傻裝成RHEL7的

[root@supermic2 fio]# wget ftp://195.220.108.108/linux/dag/redhat/el6/en/x86_64/dag/RPMS/fio-2.1.10-1.el6.rf.x86_64.rpm
