解決 libev.so.4()(64bit) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64案例
zping發表於2017-12-22
- 在mysql主從同步時經常會用到Xtra, XtraBackup可以說是一個相對完美的免費開源資料備份工具，支援線上無鎖表同步複製和可並行高效率的安全備份恢復機制相比mysqldump來說優勢較大好處多,在RHEL6中安裝XtraBackup時會發生缺少依賴包的現象
-
- 本案例針對Xtra缺少依賴包的情況進行安裝分析解決
-
- 1.本實驗環境
-
- [root@master ~]# uname -r
- 2.6.32-573.el6.x86_64
-
- [root@master ~]# cat /etc/redhat-release
- Red Hat Enterprise Linux Server release 6.7 (Santiago)
-
- mysql> select version();

- 下載完成後進行解壓

- 3.安裝排錯步驟
-
- 3.1 在安裝過程中發現缺少依賴包lib和perl,原則上能用yum解決的就優先用yum解決，yum解決不掉的可以用網上的yum源或者自己單獨下載rpm包進行安裝
-
- [root@master ~]# rpm -ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm
- warning: percona-xtrabackup-2.3.4-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
- error: Failed dependencies:
- libev.so.4()(64bit) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64
- perl(DBD::mysql) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64
-
-
- 3.2 使用本地yum源安裝libev與perl-DBI,但libev.so.4安裝失敗，是由於本地yum源沒有該rpm包，我這裡使用網上下載的rpm包進行安裝
-
- [root@master ~]# yum install libev.so.4
- Loaded plugins: aliases, changelog, kabi, presto, product-id, security, subscription-manager, tmprepo, verify, versionlock

- Setting up Install Process
- file:
- Trying other mirror.
- No package libev.so.4 available.
- Error: Nothing to do
-
- 3.3 安裝perl-DBD-MySQL 成功完成
- [root@master ~]# yum install perl-DBD-MySQL
- Loaded plugins: aliases, changelog, kabi, presto, product-id, security, subscription-manager, tmprepo, verify, versionlock
