linux mysql8.0二进制部署安装
作者：互联网
二进制部署8版本：
卸载mariadb软件：
[root@mysql ~]# rpm -qa |grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64
[root@mysql ~]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
解压二进制包：
[root@mysql ~]# wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz
[root@mysql ~]# tar -xf mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz -C /usr/local
[root@mysql ~]# mv /usr/local/mysql-8.0.16-linux-glibc2.12-x86_64 /usr/local/mysql-8.0.16
[root@mysql ~]# mkdir /usr/local/mysql-8.0.16/{data,logs}
[root@mysql ~]# touch /usr/local/mysql-8.0.16/logs/mysql.log
创建mysql用户：
[root@mysql ~]# groupadd mysql
[root@mysql ~]# useradd mysql -g mysql
[root@mysql ~]# chown -R mysql.mysql /usr/local/mysql-8.0.16
初始化数据：
# 加上--initialize参数是开启临时密码、安全策略（密码过期时间）------------（当前使用为无密码、无安全策略）
[root@mysql ~]# /usr/local/mysql-8.0.16/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql-8.0.16 --datadir=/usr/local/mysql-8.0.16/data
添加配置文件：
[root@mysql ~]# vim /etc/my.cnf
[mysqld]
server_id=1
user=mysql
port=3306
bind-address=0.0.0.0
basedir=/usr/local/mysql-8.0.16
datadir=/usr/local/mysql-8.0.16/data
socket=/tmp/mysql.sock
log_error=/usr/local/mysql-8.0.16/logs/mysql.log
[mysql]
socket=/tmp/mysql.sock
启动MySQL-8.0服务：
[root@mysql ~]# cp -a /usr/local/mysql-8.0.16/support-files/mysql.server /etc/init.d/mysqld
[root@mysql ~]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/usr/local/mysql-8.0.16/data/mysql.err'.
.. SUCCESS!

添加mysql环境变量：
[root@mysql ~]# echo 'export PATH=/usr/local/mysql-8.0.16/bin:$PATH' >> /etc/profile
[root@mysql ~]# source /etc/profile
修改root随机密码：
[root@mysql ~]# mysql
