MySQL 8.0二进制包安装
安装包下载
1.官方下载
服务器中操作
1.删除之前安装的MySQL包
[root@server02 etc]# rpm -qa | grep mariadb mariadb-libs-5.5.68-1.el7.x86_64 mariadb-devel-5.5.68-1.el7.x86_64 [root@server02 etc]# yum erase -y mariadb-libs-5.5.68-1.el7.x86_64
2.解压缩
[root@server02 ~]# tar xf mysql-8.0.12-linux-glibc2.12-x86_64.tar.xz [root@server02 ~]# mv mysql-8.0.12-linux-glibc2.12-x86_64 /usr/local/mysql [root@server02 ~]# cd /usr/local/mysql/ [root@server02 mysql]# groupadd mysql [root@server02 mysql]# useradd -r -g mysql -s /sbin/nologin mysql [root@server02 mysql]# mkdir /usr/local/mysql/data [root@server02 mysql]# mkdir /usr/local/mysql/etc [root@server02 mysql]# mkdir /usr/local/mysql/log [root@server02 mysql]# chown -R mysql:mysql /usr/local/mysql/ [root@server02 mysql]# vim /usr/local/mysql/etc/my.cnf
3.编辑mysql配置文件
[root@server02 etc]# cat /usr/local/mysql/etc/my.cnf [mysql] port = 3306 socket = /usr/local/mysql/data/mysql.sock [mysqld] port = 3306 mysqlx_port = 33060 mysqlx_socket = /usr/local/mysql/data/mysqlx.sock basedir = /usr/local/mysql datadir = /usr/local/mysql/data socket = /usr/local/mysql/data/mysql.sock pid-file = /usr/local/mysql/data/mysqld.pid log-error = /usr/local/mysql/log/error.log #这个就是用之前的身份认证插件 default-authentication-plugin = mysql_native_password #保证日志的时间正确 log_timestamps = SYSTEM
4.初始化数据库,并查看日志
[root@server02 mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data [root@server02 mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld [root@server02 mysql]# /etc/init.d/mysqld start
切记要把/etc/my.cnf删除掉，要不然启动时会报错。 [root@server02 etc]# /etc/init.d/mysqld start Starting MySQL.... SUCCESS! [root@server02 ~]# tailf /usr/local/mysql/log/error.log 2020-12-29T01:02:05.915655Z 0 [Warning] [MY-011070] [Server] 'Disabling symbolic links using --skip-symbolic-links (or equivalent) is the default. Consider not using this option as it' is deprecated and will be removed in a future release. 2020-12-29T09:02:05.916174+08:00 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.12) initializing of server in progress as process 8108 2020-12-29T09:02:18.045798+08:00 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: qr11AqDgis.d 2020-12-29T09:02:23.220369+08:00 0 [System] [MY-013170] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.12) initializing of server has completed
记住这个临时密码，后边要用到
5.配置环境变量
[root@server02 etc]# vim /etc/profile PATH=$PATH:$HOME/bin:/usr/local/mysql/bin [root@server02 etc]# source /etc/profile
6.登录并配置远程登录
[root@server02 etc]# source /etc/profile [root@server02 etc]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
