检验是否安装成功

[root@root mysql-5.7.12]#    cd /usr/local/mysql/
[root@root mysql]#    ls
bin      data  include  man         mysql.sock.lock  README  support-files
COPYING  docs  lib      mysql.sock  mysql-test       share

新建目录

mkdir -p /data/db/mysql/
mkdir -p /data/log/mysql/

增加配置文件

mkdir /usr/local/mysql/etc
touch /usr/local/mysql/etc/my.cnf
ln -s /usr/local/mysql/etc/my.cnf /usr/local/etc

修改权限

chown -R mysql:mysql /usr/local/mysql/*
chown -R mysql:mysql /data/db/mysql /data/log/mysql

生成初始化密码

cd /usr/local/mysql
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/db/mysql
bin/mysql_ssl_rsa_setup
vim /data/log/mysql/error.log
查看初始化密码
grep 'temporary password' /data/log/mysql/error.log

将mysql的启动服务添加到系统服务中

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system
mkdir -p /var/run/mysqld/
chown mysql:mysql /var/run/mysqld
systemctl start mysqld
service mysql start

启动mysql

service mysqld start
检查mysql启动是否正常
service mysqld status 或者 ps -ef | grep mysql
设置mysqld服务开机自启动
systemctl enable mysqld.service
检查mysqld开机自启动是否设置成功
systemctl list-dependencies | grep mysqld

修改mysql密码，以及远程连接权限

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Studytime%';
use mysql;
select host, user from user;
update user set host = '%' where user = 'root';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Studytime%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
