MySQL 5.6.39 二进制安装
CentOS 7 将默认数据库
这里会从系统的环境准备开始一步一步安装。MySQL替换成了Mariadb。
环境准备
| 系统版本 | 内核版本 | IP地址 |
|---|---|---|
| Centos 7.5 | 4.18.9-1.el7.elrepo.x86_64 | 10.0.0.3 |
备注 该系统采用MINI最小化安装，安装之后对系统进行了最基础的优化操作，
删除系统自带的依赖包
[root@node soft]# rpm -qa | egrep 'mysql|mariadb'mariadb-libs-5.5.56-2.el7.x86_64[root@node soft]# rpm -qa | egrep 'mysql|mariadb' | xargs rpm -e --nodeps[root@node soft]# rpm -qa | egrep 'mysql|mariadb'[root@node soft]#
创建MySQL运行用户
[root@node soft]# useradd -s /sbin/nologin -M mysql[root@node soft]# grep mysql /etc/passwdmysql:x:1000:1000::/home/mysql:/sbin/nologin
下载 MySQL
可以在mirrors.163.com的163源下载，
如果上面的下载地址失效了，则可以使用百度网盘：链接：https://pan.baidu.com/s/1Sln84TrPQhA2jyt_t51X1Q

配置环境变量
[root@node soft]# mv mysql-5.6.39-linux-glibc2.12-x86_64 /opt/mysql[root@node soft]# chown -R mysql.mysql /opt/mysql[root@node soft]# cd /opt/[root@node opt]# lsmysql[root@node opt]# echo 'export PATH=$PATH:/opt/mysql/bin' >> /etc/profile[root@node opt]# tail -1 /etc/profileexport PATH=$PATH:/opt/mysql/bin[root@node opt]# source /etc/profile[root@node opt]# mysql -Vmysql Ver 14.14 Distrib 5.6.39, for linux-glibc2.12 (x86_64) using EditLine wrapper
配置MySQL启动脚本并设置开机自启
二进制解压后的目录中，包括了MySQL的启动关闭脚本，可以使用，也可以自己写
systemctl管理脚本
[root@node opt]# cd mysql/[root@node mysql]# pwd/opt/mysql[root@node mysql]# cp support-files/mysql.server /etc/init.d/mysqld[root@node mysql]# chmod +x /etc/init.d/mysqld [root@node mysql]# sed -i 's#/usr/local#/opt#g' /etc/init.d/mysqld[root@node mysql]# chkconfig --add mysqld[root@node mysql]# chkconfig mysqld on[root@node mysql]# chkconfig | grep mysqlNote: This output shows SysV services only and does not include native systemd services. SysV configuration data might be overridden by native systemd configuration. If you want to list systemd services use 'systemctl list-unit-files'. To see services enabled on particular target use 'systemctl list-dependencies [target]'.mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
