一、简介
二进制安装方式，升级版本相对简单可靠。本案例基于二进制安装方式进行升级演示。
先完整的安装mariadb10.4版本，然后在此基础上升级到10.5版本。
二、Centos7.6最小化安装依赖包
yum install -y net-tools yum install -y wget #切换aliyun的yum源 cd /etc/yum.repos.d/ mv CentOS-Base.repo CentOS-Base.repo.bak wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo # 重建源数据缓存 yum clean all yum makecache yum -y install vim-enhanced wget net-tools telnet vim lrzsz ntp yum -y install lshw pciutils gdisk system-storage-manager yum -y install bash-completion zip unzip bzip2 tree tmpwatch pinfo man-pages yum -y install nano vim-enhanced tmux screen yum -y install net-tools psmisclsof sysstat yum -y install yum-plugin-security yum-utils createrepo yum -y install get wget curl eliks lynx lftp mailx mutt reync yum -y install libaio make cmake gcc-c++ gcc zib zlib-devel open openssl-devel pcre pcre-devel
三、创建用户
useradd -M -r -s /bin/nologin mysql echo "mysql"|passwd --stdin mysql
四、下载安装
wget https://downloads.mariadb.org/interstitial/mariadb-10.4.11/bintar-linux-systemd-x86_64/mariadb-10.4.11-linux-systemd-x86_64.tar.gz/from/http%3A//mariadb.mirror.nucleus.be/ tar -zxvf mariadb-10.4.11-linux-systemd-x86_64.tar.gz -C /usr/local/ cd /usr/local/ ln -s mariadb-10.4.11-linux-systemd-x86_64/ mysql echo "PATH=/usr/local/mysql/bin:$PATH" > /etc/profile.d/mysql.sh
五、配置文件
