CentOS7安装、配置MariaDB集群问题总结

安装percona-xtrabackup

创建文件/etc/yum.repos.d/Percona.repo内容如下:

[percona]
name = CentOS $releasever - Percona
baseurl=http://repo.percona.com/centos/ releasever/os/ basearch/
enabled = 1
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-percona
gpgcheck = 1

获取和保存key

#wget http://www.percona.com/redir/downloads/percona-release/RPM-GPG-KEY-percona

#cp RPM-GPG-KEY-percona /etc/pki/rpm-gpg/RPM-GPG-KEY-percona

安装 percona xtrabackup

#yum -y install percona-xtrabackup

安装Xtrabackup 提示缺少libev.so.4()

其实是因为percona-xtrabackup依赖libev.so.4()(64bit)的包，而这个包只能从EPEL源(Extra Packages for Enterprise Linux，企业版Linux的额外软件包 是Fedora小组维护的一个软件仓库项目，为RHEL/CentOS提供他们默认不提供的软件包)安装 ,所以只要安装了这个包即可解决问题.

从http://rpmfind.net/linux/rpm2html/search.php上下载libev安装包，然后安装即可，如下所示

# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm

安装socat缺少Libreadline.so.5
