下载二进制包并安装
将下载的二进制包放在安装目录 /usr/local/ 下，并解压缩：
# 下载
$ cd /usr/local
$ wget wget https://product.greatdb.com/GreatSQL-8.0.32-26/GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64.tar.xz
#或者用curl
$ curl -o GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64.tar.xz https://product.greatdb.com/GreatSQL-8.0.32-26/GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64.tar.xz
#解压缩
$ tar xf GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64.tar.xz
编辑systemd系统服务文件，增加GreatSQL服务文件：务必确认文件中目录及文件名是否正确。
vi /usr/lib/systemd/system/greatsql.service

执行命令重载systemd，加入 greatsql 服务，如果没问题就不会报错：
这就安装成功并将GreatSQL添加到系统服务中，后面可以用 systemctl 来管理GreatSQL服务。
systemctl daemon-reload
编辑GreatSQL全局配置文件 /etc/my.cnf，加入下面内容并保存退出

创建mysql系统用户：
$ /sbin/groupadd mysql
$ /sbin/useradd -g mysql mysql -d /dev/null -s /sbin/nologin
创建相关文件夹，并修改用户组(将文件中的 /usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64/改为实际安装目录)：
mkdir /var/run/mysqld/ /var/lib/mysql-files/ /var/lib/mysql/
chown mysql:mysql /var/run/mysqld/ /var/lib/mysql-files/ /var/lib/mysql/ /usr/local/GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64/
启动GreatSQL
执行下面的命令启动GreatSQL服务
systemctl start greatsql
检查服务是否已启动，以及进程状态：

连接登入GreatSQL
采用minimal二进制包安装GreatSQL后，通过log-error日志查看初始化密码，即可登入。
$ cat /var/log/mysqld.log|grep password
[Note] [MY-010454] [Server] A temporary password is generated for root@localhost: NrkNcJya<9f6
若使用了GreatSQL推荐的my.cnf则错误日志路径发生改变，请使用以下命令查看初始化密码
$ $ grep -i root /data/GreatSQL/error.log
... A temporary password is generated for root@localhost: ji!pjndiw5sJ
复制密码即可登入GreatSQL
/usr/local/GreatSQL-8.0.32-26-Linux-glibc2.17-x86_64/bin/mysql -uroot -p'ji!pjndiw5sJ'

登录报错：ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决办法:将sock文件建立软连接到mysql用到的sock文件
ln -s /data/GreatSQL/mysql.sock /tmp/mysql.sock
登录报错：ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
解决办法:实现免密登录
/etc/my.cnf 添加 skip-grant-tables
然后重启数据库：systemctl restart greatsql
修改密码
ALTER USER 'root'@'%' IDENTIFIED BY 'passwd';
FLUSH PRIVILEGES;
实现远程登录
update user set host = '%' where user = 'root';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
