二、 二进制安装
#下载解压安装包
[root@hadoop03 ~]# wget -c https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.39-linux-glibc2.17-x86_64.tar.xz
[root@hadoop03 ~]# xz -d mysql-8.0.39-linux-glibc2.17-x86_64.tar.xz
[root@hadoop03 ~]# tar -xvf mysql-8.0.39-linux-glibc2.17-x86_64.tar
[root@hadoop03 ~]# mv mysql-8.0.39-linux-glibc2.17-x86_64 mysql
[root@hadoop03 ~]# mv mysql /usr/local/
#创建数据存放目录以及日志目录、mysql.sock文件存放目录
[root@hadoop03 mysql]# mkdir /data/mysql/{data,logs,run} -p
#以普通用户启动mysql，所以需要更改目录权限
[root@hadoop03 mysql]# chown admin:admin -R /usr/local/mysql/
[root@hadoop03 mysql]# chown admin:admin -R /data/
#编写配置文件my.cnf
[root@hadoop03 mysql]# su admin
[admin@hadoop03 mysql]$ vi my.cnf
[mysqld_safe]
pid-file=/data/mysql/logs/mysqld.pid
[mysqld]
basedir=/usr/local/mysql
datadir=/data/mysql/data
socket=/data/mysql/run/mysql.sock
log_error=/data/mysql/logs/alert.log
pid_file=/data/mysql/logs/mysqld.pid
#初始化mysql
[admin@hadoop03 mysql]$ ./bin/mysqld --defaults-file=/usr/local/mysql/my.cnf --initialize-insecure
#启动mysql
[admin@hadoop03 mysql]$ ./bin/mysqld_safe --defaults-file=my.cnf &
#进入mysql，也可以./bin/mysql -S /data/mysql/run/mysql.sock命令进入
[admin@hadoop03 mysql]$ ./bin/mysql -uroot -h127.0.0.1
