1.解压文件到/usr/local目录，并将文件夹重命名为mysql(或者增加软连接)

cp mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz

/usr/local/

cd /usr/local/ #数据库程序目录

tar -zxf

mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz

mv mysql-8.0.11-linux-glibc2.12-x86_64

mysql

(ln -s

/usr/local/mysql-8.0.11-linux-glibc2.12-x86_64

/usr/local/mysql)

2.初始化配置mysql

userdel mysql # 删除用户

groupdel mysql # 删除用户组名

groupadd mysql # 创建一个名为mysql的用户组

useradd -g mysql -s /sbin/nologin mysql

# 在用户组下创建用户

chown mysql:mysql mysql -R

#程序目录mysql权限

chmod 750 /usr/local/mysql -R

cd mysql

mkdir mysqldata #数据存放目录

chown mysql:mysql mysqldata -R

chmod 750 mysqldata/

#因为目前没有数据，所以此步可以不用

cd /var/log/ #配置log存放文件

mkdir mysql

cd mysql/

touch mysql.log

chown mysql:mysql /var/log/mysql/

-R

vim /usr/local/mysql/my.cnf

#编辑数据库配置文件，注意文件权限

vim /etc/profile #修改环境变量

alias

source /etc/profile

mysql -u root -p #mysql命令可以使用

以上是我的操作过程，重复了三遍没有问题。

但是同事在操作测试环境的时候，启动Mysql失败，提示"The server quit without updating PID

file"

经过排查是log文件权限不够导致，增加权限后Server启动成功
