MySQL 8.0二进制包安装
安装包下载
1.官方下载
这样就可以下载二进制包了
服务器中操作
1.删除之前安装的MySQL包
[root@localhost ~]# rpm -qa | grep mariadb mariadb-libs-5.5.60-1.el7_5.x86_64 [root@localhost ~]# yum erase -y mariadb-libs-5.5.60-1.el7_5.x86_64
2.解压缩
tar -xf mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz
3.重命名并移动到/usr/local/mysql
mv mysql-8.0.13-linux-glibc2.12-x86_64 /usr/local/mysql
4.创建mysql用户和组
groupadd mysql
useradd -r -g mysql -s /sbin/nologin mysql
5.创建数据目录，日志目录，配置文件目录,变更权限
mkdir /usr/local/mysql/data mkdir /usr/local/mysql/etc mkdir /usr/local/mysql/log chown -R mysql:mysql /usr/local/mysql/
6.编辑mysql配置文件
vim /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
7.初始化数据库,并查看日志
cd /usr/local/mysql bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data tailf /usr/local/mysql/log/error.log 2019-01-13T20:27:49.270330+08:00 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.13) initializing of server in progress as process 6990 2019-01-13T20:27:53.320375+08:00 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: SV!sgk7?k0i= 2019-01-13T20:27:54.805257+08:00 0 [System] [MY-013170] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.13) initializing of server has completed
记住这个临时密码，后边要用到
8.设置启动文件，设置环境变量
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld /etc/init.d/mysqld start Starting MySQL.. SUCCESS! [root@localhost ~]# ps -ef | grep mysql root 7072 1 0 20:30 pts/0 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/mysqld.pid mysql 7287 7072 7 20:30 pts/0 00:00:01 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/log/error.log --pid-file=/usr/local/mysql/data/mysqld.pid --socket=/usr/local/mysql/data/mysql.sock --port=3306 root 7334 6821 0 20:30 pts/0 00:00:00 grep --color=auto mysql
配置环境变量
vim /etc/profile PATH=$PATH:$HOME/bin:/usr/local/mysql/bin source /etc/profile
9.登录并配置远程登录
[root@localhost ~]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

这就行了
