MySQL 8.0二进制包安装

1.官方下载

https://dev.mysql.com/downloads/mysql/

这样就可以下载二进制包了

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:
