linux mysql8.0二进制部署安装

本文主要是介绍linux mysql8.0二进制部署安装，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

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! 

或者---------------------------------------------------------------------------------------------

[root@mysql ~]# vim /etc/systemd/system/mysqld.service

[root@mysql ~]# systemctl start mysqld.service
[root@mysql ~]# systemctl enable mysqld.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mysqld.service to /etc/systemd/system/mysqld.service.


[root@mysql ~]# netstat -tunpl |grep 3306
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      1232/mysqld

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
