說明：

mysql安裝在/data/mysql-5.6.35目錄下；

如果安裝在/usr/local/mysql/目錄下,則兩個sed不許執行，因為默認是/usr/local/目錄下；

1.下載

cd /data/

tar -zxf ?mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

mv?mysql-5.6.35-linux-glibc2.5-x86_64?/data/mysql-5.6.35

2.新建mysql用戶及設置權限

sudo useradd?-s?/sbin/nologin?-M?mysql

mkdir -pv ?/data/mysql-5.6.35/{var,log}

touch /data/mysql-5.6.35/log/error.log

sudo chown?-R?mysql:mysql?/data/mysql-5.6.35/

3.添加環境變量：

vim ~/.bash_profile

export PATH=/data/mysql-5.6.35/bin:$PATH

source ~/.bash_profile

4.初始化數據庫,修改默認路徑

cd /data/mysql-5.6.35/

sudo ./scripts/mysql_install_db?--basedir=/data/mysql-5.6.35/?--datadir=/data/mysql-5.6.35/data/?--user=mysql

sudo sed?-i?'s#/usr/local/mysql#/data/mysql-5.6.35#g'?/data/mysql-5.6.35/bin/mysqld_safe

sudo sed?-i?'s#/usr/local/mysql#/data/mysql-5.6.35#g'?/data/mysql-5.6.35/support-files/mysql.server

sudo ln -s /data/mysql-5.6.35/bin/mysql /usr/bin

5.修改配置文件

sudo rm –f /etc/my.cnf

sudo vim /data/mysql-5.6.35/my.cnf

[client]

port ? ? ? = 3306

socket ? = /tmp/mysql.sock

[mysqld]

server-id ?= 1

port ? ? ?= 3306

basedir = /data/mysql-5.6.35

datadir ?= /data/mysql-5.6.35/data

socket ?= /tmp/mysql.sock

binlog-ignore-db ?= mysql

log-bin ?= /data/mysql-5.6.35/log/mysql-bin

innodb_file_per_table = 1

open_files_limit ?= 65535

sql_mode ?=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

skip-host-cache

skip-name-resolve

max_connections ?= 1024

wait_timeout ?= 31536000

interactive_timeout = 31536000

character-set-server ?=utf8mb4

collation-server ?= utf8mb4_general_ci

init_connect ?= 'SET NAMES utf8mb4'

lower_case_table_names = 1

log_error ?= /data/mysql-5.6.35/log/error.log

slow_query_log = 1

slow_query_log_file = /data/mysql-5.6.35/log/slow.log

[mysqld_safe]

err-log= /data/mysql-5.6.35/log/mysqld_safe_err.log

pid-file = /data/mysql-5.6.35/var/mysqld.pid

6.將服務腳本復制到/etc/init.d目錄下，并添加到服務列表

sudo cp ?support-files/mysql.server ?/etc/init.d/mysqld

7.開機自啟動

sudo chkconfig --add mysqld

sudo chkconfig mysqld on

sudo chkconfig --list mysqld

8.啟動mysql

sudo ?/etc/init.d/mysqld start

ps –ef | grepmysql

9.設置mysql密碼

sudo /data/mysql-5.6.35/bin/mysqladmin -u root password 'newpassword'

10.登錄

mysql ?-uroot?? -p

11.配置安全策略：

[root@KVM mysql-5.6.35]#sudo /data/mysql-5.6.35/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

SERVERS IN PRODUCTION USE!? PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current

password for the root user.? Ifyou've just installed MySQL, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n]?n

... skipping.

By default, a MySQL installation has an anonymous user, allowing anyone

to log into MySQL without having to have a user account created for

them.? This is intended only fortesting, and to make the installation

go a bit smoother.? You shouldremove them before moving into a

production environment.

Remove anonymous users? [Y/n]?y

... Success!

Normally, root should only be allowed to connect from 'localhost'.? This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]n

... Success!

By default, MySQL comes with a database named 'test' that anyone can

access.? This is also intended only fortesting, and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n]?y

- Dropping test database...

... Success!

- Removing privileges on testdatabase...

... Success!

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n]?y

... Success!

All done!? If you've completed allof the above steps, your MySQL

installation should now be secure.

Thanks for using MySQL!

Cleaning up...
