make

make install

useradd mysql -s /sbin/nologin #/sbin/nologin意思是用户不允许登录（通过ftp可以连接）

chown -R mysql:mysql /data/mysql-5.7.16/ #变更所属组、用户

cd /data/mysql-5.7.16/

#配置环境变量

# echo "export PATH=$PATH:/data/mysql-5.7.16/lib:/data/mysql-5.7.16/bin:" >> /etc/profile

# source /etc/profile

五、创建单实例数据、日志等文件存放路径，如下树形结构,并更改所属组用户

1 /data

2 ├── mysql-5.7.16

4 │ ├── my.cnf

3 ├── mysql5.7.16data

4 │ ├── mysql3220

5 │ │ ├── data

6 │ │ ├── mysqld.pid

7 │ │ ├── mysql.sock

8 │ │ └── mysql.sock.lock

9├── mysql5.7.16log

10│ ├── mysql3220

11│ │ ├── binlogs

12│ │ └── relaylogs

13│ ├── mysqld-5.7-err.log

14│ ├── mysql_multi.log

15│ └── slow.log

# mkdir -p/data/mysql5.7.16data/mysql3220

# mkdir -p/data/mysql5.7.16log/mysql3220/binlogs

# mkdir -p/data/mysql5.7.16log/mysql3220/relaylogs

# chown -R mysql.mysql /data/mysql5.7.16data/

# chown -R mysql.mysql /data/mysql5.7.16log/

六、初始化MySQL[ 初始化完成后会自带随机密码在输出日志中 ]

# /data/mysql-5.7.16/bin/mysqld --initialize --basedir=/data/mysql-5.7.16/ --datadir=/data/mysql5.7.16data/mysql3220/data --user=mysql

七、开启SSL连接（可选）

# /data/mysql-5.7.16/bin/mysql_ssl_rsa_setup --user=mysql --basedir=/data/mysql-5.7.16/ --datadir=/data/mysql5.7.16data/mysql3220/data

八、配置MySQL配置文件

# rmdir /etc/my.cnf.d/

# rm -rf /etc/my.cnf

# rsync

# vi mysql-5.7.16/my.cnf

[client]

九、复制服务脚本并添加到服务中

cp support-files/mysql.server /etc/init.d/mysql5.7

chmod +x /etc/init.d/mysql5.7

chkconfig --add mysql5.7

chkconfig --level 2345 mysql5.7 on

十、设置MySQLroot密码

# 重启MySQL

service mysql5.7 restart

第一种：根据初始化后生产的随机密码设置MySQLroot密码：

# mysql -S /data/mysql-5.7.16/etc/mysql.sock -p'dORk8uo,Djqx'

MySQL>SET PASSWORD FOR 'root'@'localhost' = PASSWORD('xxxxx');

MySQL> flush privileges;

MySQL>GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1'IDENTIFIED BY 'xxxxx' WITH GRANT OPTION;

MySQL> flush privileges;

MySQL> exit;

MySQL # mysql -h127.0.0.1 -P 3220 -uroot -pxxxxx

第二种：（依据官方说明5.6以后版本，第一次启动时会在root目录下生产一个随机密码，文件名.mysql_secret。）

mysql

cat/root/.mysql_secret

****mysql_secure_installation

/etc/init.d/mysql5.7 restart

mysql -p

# mysql -p

Enter password: #此行输入.mysql_secret里第二行内容

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('xxxxx'); #修改root密码

mysql> flush privileges;

exit

mysql -uroot -pxxxx

*区别在于：

第一种初始化方式是在安装目录/data/mysql-5.7.16/bin/mysqld --initialize --basedir=/data/mysql-5.7.16/ --datadir=/data/mysql5.7.16data/mysql3220/data --user=mysql利用mysqld进行初始化【推荐】
第二种初始化方式是在解压目录/data/soft/mysql-5.7.16/client/mysql_install_db --basedir=/data/mysql-5.7.16/ --datadir=/data/mysql-5.7.16/data --user=mysql利用mysql_install_db进行初始化

我们可以看到root@localhost 被赋予随机生成的一个密码，这与以往的mysql版本不一样，另外mysql_install_db 这个工具也不再被推荐了， mysql_install_db is deprecated. Please consider switching to mysqld --initialize。另外，在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）
