本文记录了linux mysql 8.0.18 安装配置图文教程,供大家参考,具体内容如下
1、官网安装包下载地址
2、我这里通过xftp将安装包上传至Linux服务器
3.解压
解压命令:tar -xvf mysql-8.0.18-linux-glibc2.12-x86_64.tar
继续解压需要的那一个
命令: tar -xvf mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
重命名并移动到合适的路径
重命名 : mv mysql-8.0.18-linux-glibc2.12-x86_64 mysql
移动:
4.在/usr/local/mysql下创建data文件夹
# mkdir data
5.初始化数据库,自动生成密码 需记录 等下要用
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
ps:中间遇到一个坑,初始化数据库时候报了错
具体错误为:bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决方法为:yum install libaio-devel.x86_64 原因是缺少了libaio这个东西 安装就完事了
再次执行初始化命令
得到初始化密码,需要记下,一会会用到
6.修改/usr/local/mysql 当前目录的用户
# chown -R root:root ./# chown -R mysql:mysql data
7.复制my-default.cnf这个文件到etc/my.cnf去
具体命令为:
# cd support-files/# touch my-default.cnf# chmod 777 ./my-default.cnf # cd ../# cp support-files/my-default.cnf /etc/my.cnf
8.完了之后配置my.cnf
vim /etc/my.cnf
内容:
