验证编译是否成功
echo $?
执行make install
my.cnf配置文件
vi /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
修改环境变量
echo $PATH
echo “export PATH=$PATH:/usr/local/mysql/bin” >> /etc/profile
source /etc/profile
echo $PATH
添加文件夹并赋予权限
mkdir /usr/local/mysql/mysql-file
chown -R mysql.mysql /usr/local/mysql
初始化数据库
/usr/local/mysql/bin/mysqld –initialize –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data
记住密码
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig –add mysqld
chkconfig mysqld on
service mysqld start
systemctl start mysqld
systemctl status mysqld
登录数据库并修改密码
mysql -uroot -p‘Ncyrkxy30O_6
mysql> alter user root@‘localhost‘ identified by ‘P@ssw0rd‘;
mysql -uroot -pP@ssw0rd
mysqladmin -uroot -p‘P@ssw0rd‘ password ‘(P@ssw0rd)‘
