linux安装mysql8.0.x_mysql-8.3.0-linux-glibc2.27-aarch64

tar -xvf 可以解压tar.xz后缀的压缩文件
tar -zxvf 可以解压tar.gz后缀的压缩文件

（以下以mysql-8.0.32-linux-glibc2.17-aarch64.tar.gz为例）

1、解压：
tar -zxvf mysql-8.0.32-linux-glibc2.17-aarch64.tar.gz
2、重命名
mv mysql-8.0.32-linux-glibc2.17-aarch64 mysql-8.0.32
3、创建data文件夹 储存文件
cd mysql-8.0.32
mkdir data
4、创建用户组和用户
groupadd mysql
useradd -g mysql mysql
5、授权用户
chown -R mysql.mysql /usr/local/soft/mysql-8.0.32
6、mysql初始化(注意这里会生成密码，记得保存)
cd bin
./mysqld --user=mysql --basedir=/usr/local/mysql-8.0.32 --datadir=/usr/local/mysql-8.0.32/data/ --initialize   
(注：如果报错
 ./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
-bash: ./mysqld:: 没有那个文件或目录
则执行:  yum install -y libaio
参考：https://blog.csdn.net/ycsdn10/article/details/121934412
)
然后再执行一次初始化
7、编辑my.cnf
vim /etc/my.cnf

=====================下面是修改后的====================

[[mysqld]
#datadir=/var/lib/mysql 【修改点】
datadir=/usr/local/mysql-8.0.19/data
#【修改点】
basedir=/usr/local/mysql-8.0.19
【修改点】
#socket=/var/lib/mysql/mysql.sock
socket=/tmp/mysql.sock]()
 
Disabling symbolic-links is recommended to prevent assorted security risks
 
symbolic-links=0
 
Settings user and group are ignored when systemd is used.
 
If you need to run mysqld under a different user or group,
 
customize your systemd unit file for mariadb according to the
 
instructions in http://fedoraproject.org/wiki/Systemd
 
【修改点】
#[mysqld_safe]
【修改点】
#log-error=/var/log/mariadb/mariadb.log
【修改点】
#pid-file=/var/run/mariadb/mariadb.pid
 
#
 
include all files from the config directory
 
#
!includedir /etc/my.cnf.d

8、添加mysqld服务
返回mysql-8.0目录下，添加mysqld服务到系统
cp -a ./support-files/mysql.server /etc/init.d/mysql
9.授权以及添加服务
chmod +x /etc/init.d/mysql
chkconfig --add mysql
10.启动mysql
service mysql start
11.查看启动状态
service mysql status
12.将mysql命令添加到服务 
ln -s /usr/local/mysql-8.0/bin/mysql /usr/bin
13.登录
mysql -uroot -p
14.修改root密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
flush privileges;
15.修改远程连接并生效
use mysql;
update user set host='%' where user='root';
flush privileges;
16.开放防火墙3306端口
firewall-cmd --add-port=3306/tcp --permanent
firewall-cmd --reload
查看防火墙端口开放状态（看3306是否开启了）
firewall-cmd --list-all
