编译安装
make #编译很消耗系统资源，小内存可能编译通不过
make install
编译出错，删除下面文件，重新编译安装。
#rm -f CMakeCache.txt
make && make install

初始化数据库
注：
mysql_install_db 被废弃了，取而代之的是 mysqld –initialize
/usr/local/mysql5722/bin/mysqld --initialize--user=mysql --basedir=/usr/local/mysql5722 --datadir=/usr/local/mysql5722/data
#usr/local/mysql5722/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql5722 --#datadir=/usr/local/mysql5722/data--explicit_defaults_for_timestamp --defaults-file=/usr/local/mysql5722/my.cnf
之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃
"--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码
--datadir目标目录下不能有数据文件
启动数据库
service mysqld start
#/usr/local/mysql5722/bin/mysqld_safe
跳过密码验证
# cat /etc/my.cnf
[mysqld]
skip_grant_tables
设置数据库密码
mysql> alter user 'root'@'localhost' identified by'mysql';
/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1'identified by "123456" with grant option;"
/usr/local/mysql/bin/mysql -e "grant all privileges on *.* toroot@'localhost' identified by "123456" with grant option;"
修改环境变量
[root@xjfw3~]# vi /etc/profile
PATH=/usr/local/mysql5722/bin:$PATH
export PATH
#exportPATH="$PATH:/usr/local/mysql5722/bin"
[root@xjfw3 ~]# source/etc/profile
++++++++++++++
忘记root密码处理：
# mysql
ERROR 1045 (28000):Access denied for user 'root'@'localhost' (using password: NO)
配置文件中添加如下一行，跳过密码验证
# cat /etc/my.cnf
[mysqld]
skip_grant_tables
重启MySQL
# systemctl restart mysql
# mysql
mysql> update mysql.userset authentication_string=password('Oracle') where user='root' ;
再次重启MySQL
# systemctl restart mysql
# mysql
+++++++++++++++++++++++++++++++
初始化密码
mysql5.7会生成一个初始化密码，而在之前的版本首次登陆不需要登录。
shell> cat/root/.mysql_secret
# Password set for user'root@localhost' at 2015-04-22 22:13:23
?G5W&tz1z.cN
修改默认密码
shell> bin/mysqladmin -hlocalhost -u root password '123@qwe' -p'?G5W&tz1z.cN'
mysqladmin: [Warning] Usinga password on the command line interface can be insecure.
Warning: Since password willbe sent to server in plain text, use ssl connection to ensure password safety
++++++++++++++++++++++++++++++++++++++++++++
另外mysql5.7的mysql.user表结构被修改
修改mysql.user方式修改密码
mysql> update mysql.userset authentication_string=password('123qwe') where user='svoid' and Host ='localhost';
Query OK, 1 row affected(0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected(0.00 sec)
++++++++++++
7、启用远程连接：
mysql数据库远程访问设置方法
1、修改localhost
更改"mysql"数据库里的"user"表里的"host"项，从"localhost"改成"%"
mysql>use mysql;
mysql>update user set host = '%' where
user = 'root';
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;
