一、安装环境：

操作系统：ubuntu16.04

数据库：mysql-5.7.17-linux-glibc2.5-x86_64 （免安装版）

二、解压

tar -xzvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.7.17-linux-glibc2.5-x86_64   /usr/local/mysql

三、增加用户和组

groupadd mysql;

useradd -g mysql mysql;

四、创建目录及目录权限：

mkdir /mysql /mysql/data /mysql/log

  修改目录权限

   chown -R mysql:mysql /usr/local/mysql /mysql

五、在/etc目录下创建文件：my.cnf

  直接使用 vi my.cnf创建

1. [client]
2. port = 3306
3. socket = /tmp/mysql.sock
4. [mysqld]
5. server_id=10
6. port = 3306
7. user = mysql
8. socket = /tmp/mysql.sock
9. basedir = /usr/local/mysql
10. datadir = /mysql/data
11. pid-file = /mysql/data/mysql.pid
12. max_connections = 1000
13. max_connect_errors = 1000
14. table_open_cache = 1024
15. max_allowed_packet = 128M
16. open_files_limit = 65535
17. #####====================================[innodb]==============================
18. innodb_buffer_pool_size = 1024M
19. innodb_file_per_table = 1
20. innodb_write_io_threads = 4
21. innodb_read_io_threads = 4
22. innodb_purge_threads = 2
23. innodb_flush_log_at_trx_commit = 1
24. innodb_log_file_size = 512M
25. innodb_log_files_in_group = 2
26. innodb_log_buffer_size = 16M
27. innodb_max_dirty_pages_pct = 80
28. innodb_lock_wait_timeout = 30
29. innodb_data_file_path=ibdata1:1024M:autoextend
30. #####====================================[log]==============================
31. log_error = /mysql/log/mysql-error.log
32. slow_query_log = 1
33. long_query_time = 1
34. slow_query_log_file = /mysql/log/mysql-slow.log
35. sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

[client]
port = 3306
socket = /tmp/mysql.sock

[mysqld]

server_id=10

port = 3306

user = mysql

socket = /tmp/mysql.sock

basedir = /usr/local/mysql

datadir = /mysql/data

pid-file = /mysql/data/mysql.pid

max_connections = 1000

max_connect_errors = 1000

table_open_cache = 1024

max_allowed_packet = 128M

open_files_limit = 65535
======[innodb]

innodb_buffer_pool_size = 1024M

innodb_file_per_table = 1

innodb_write_io_threads = 4

innodb_read_io_threads = 4

innodb_purge_threads = 2

innodb_flush_log_at_trx_commit = 1

innodb_log_file_size = 512M

innodb_log_files_in_group = 2

innodb_log_buffer_size = 16M

innodb_max_dirty_pages_pct = 80

innodb_lock_wait_timeout = 30

innodb_data_file_path=ibdata1:1024M:autoextend
======[log]

log_error = /mysql/log/mysql-error.log

slow_query_log = 1

long_query_time = 1

slow_query_log_file = /mysql/log/mysql-slow.log

sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

六、初始化数据库及配置

注意：5.7.6之后的版本初始化数据库不再使用mysql_install_db

  bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data  --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp

如果配置了my.cnf的log_error，那么初始密码在log_error文件中，否则会打印出来。

  bin/mysql_ssl_rsa_setup --datadir=/mysql/data

  修改目录权限

 chown -R mysql:mysql /usr/local/mysql /mysql

  配置启动文件

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

  配置环境变量

  mysql_home=/usr/local/mysql
  PATH=$PATH:$mysql_home/bin

七、配置数据库密码及远程访问：

使用初始化密码进行登录：

密码存储在日志文件中：sudo vi mysql-error.log

mysql -u root -p *******

 初次使用，设置root密码：
   SET PASSWORD=PASSWORD('root');

然后才可以使用和操作数据库进行修改：

   update mysql.user set authentication_string=password('root') where user='root';

修改远程访问权限

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root_password' WITH GRANT OPTION;

       mysql> FLUSH PRIVILEGES ;

八、ubuntu下增加mysql到系统默认启动

  sudo update-rc.d mysql defaults
