1.下載安裝包
cd
mkdir download
cd download
wget -c -m -O mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
2.創建用戶和組
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql
3.解壓到指定目錄
cd
cd download
tar -zxvf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz -C /usr/local
cd /usr/local/
ln -s mysql-5.7.20-linux-glibc2.12-x86_64 mysql
4.配置PATH
echo “export PATH=$PATH:/usr/local/mysql/bin” >> /etc/profile
source /etc/profile
5.數據庫目錄規划
文件類型 實例3306 軟鏈
數據datadir /usr/local/mysql/data /data/mysql/data
參數文件my.cnf /usr/local/mysql/etc/my.cnf
錯誤日志log-error /usr/local/mysql/log/mysql_error.log
二進制日志log-bin /usr/local/mysql/binlogs/mysql-bin /data/mysql/binlogs/mysql-bin
慢查詢日志slow_query_log_file /usr/local/mysql/log/mysql_slow_query.log
套接字socket文件 /usr/local/mysql/run/mysql.sock
pid文件 /usr/local/mysql/run/mysql.pid
備注：考慮到數據和二進制日志比較大，需要軟鏈
創建目錄並賦權給MySQL用戶
mkdir -p /data/mysql/{data,binlogs,log,etc,run}
ln -s /data/mysql/data /usr/local/mysql/data
ln -s /data/mysql/binlogs /usr/local/mysql/binlogs
ln -s /data/mysql/log /usr/local/mysql/log
ln -s /data/mysql/etc /usr/local/mysql/etc
ln -s /data/mysql/run /usr/local/mysql/run
chown -R mysql.mysql /data/mysql/
chown -R mysql.mysql /usr/local/mysql/{data,binlogs,log,etc,run}
也可以只對數據目錄和二進制日志目錄軟鏈
mkdir -p /usr/local/mysql/{log,etc,run}
mkdir -p /data/mysql/{data,binlogs}
ln -s /data/mysql/data /usr/local/mysql/data
ln -s /data/mysql/binlogs /usr/local/mysql/binlogs
chown -R mysql.mysql /usr/local/mysql/{data,binlogs,log,etc,run}
chown -R mysql.mysql /data/mysql
6.配置my.cnf參數文件
刪除系統自帶的my.cnf
rm -f /etc/my.cnf
在/usr/local/mysql/etc/下創建my.cnf文件，加入如下參數，其他參數根據需要配置
vi /usr/local/mysql/etc/my.cnf
[client]
port = 3306
socket = /usr/local/mysql/run/mysql.sock
[mysqld]
port = 3306
socket = /usr/local/mysql/run/mysql.sock
pid_file = /usr/local/mysql/run/mysql.pid
datadir = /usr/local/mysql/data
default_storage_engine = InnoDB
max_allowed_packet = 512M
max_connections = 2048
open_files_limit = 65535
skip-name-resolve
lower_case_table_names=1
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect=’SET NAMES utf8mb4′
innodb_buffer_pool_size = 1024M
innodb_log_file_size = 2048M
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit = 0
key_buffer_size = 64M
log-error = /usr/local/mysql/log/mysql_error.log
log-bin = /usr/local/mysql/binlogs/mysql-bin
slow_query_log = 1
slow_query_log_file = /usr/local/mysql/log/mysql_slow_query.log
long_query_time = 5
tmp_table_size = 32M
max_heap_table_size = 32M
query_cache_type = 0
query_cache_size = 0
server-id=1
7.初始化數據庫
執行：
mysqld –initialize –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data
在日志文件里會提示一個臨時密碼，記錄這個密碼
grep ‘temporary password’ /usr/local/mysql/log/mysql_error.log
[Note] A temporary password is generated for root@localhost: password
8.生成ssl
mysql_ssl_rsa_setup –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data/
9.設置啟動項
CentOS 6
cd /usr/local/mysql
cp support-files/mysql.server /etc/init.d/mysql.server
chkconfig –add mysql.server
chkconfig mysql.server on
chkconfig –list
CentOS 7
cd /usr/lib/systemd/system
touch mysqld.service
編輯內容如下
vi /usr/lib/systemd/system/mysqld.service

加載
systemctl daemon-reload

10. 啟動mysql
systemctl start mysqld
11. Securing the Initial MySQL Accounts
重置密碼(上一步已經重置過了 這次可以忽略)
刪除匿名用戶
關閉root用戶的遠程登錄
刪除測試數據庫
$ /usr/local/mysql/bin/mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
The existing password for the user account root has expired. Please set a new password.
New password:
Re-enter new password:
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: Y
There are three levels of password validation policy:
LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : 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 for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : Y
Success.
By default, MySQL comes with a database named ‘test’ that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
– Dropping test database…
Success.
– Removing privileges on test database…
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y
Success.
All done!
12.Populating the Time Zone Tables
導入時區信息
$mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
13.測試
#mysqladmin version -uroot -p

15.登陸創建數據庫
mysql -uroot -p
passwd
show databases;
create database football default character set utf8 collate utf8_general_ci;
use information_schema;
grant all on football.* to socer@”%” identified by “Abc1234!”;
grant select on *.* to socer@”%” identified by “Abc1234!”;
FQ：數據庫中創建函數時候錯誤解決
1、Error Code: 1227. Access denied; you need (at least one of) the SUPER privilege(s) for this operation
— 查看是否開啟創建函數的功能
show variables like ‘%func%’;
— 開啟創建函數的功能
set global log_bin_trust_function_creators = 1;
FLUSH PRIVILEGES
2、[Err] 1055 – Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column ‘information_schema.PROFILING.SEQ’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_gr
a. 使用find命令查找名為my.cnf的文件
# find / -name my.cnf
b. 使用vi命令編輯該文件，增加以下語句：
vi /data/mysql/etc/my.cnf
sql_mode=’STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’
最終部分代碼如下所示：
character-set-server=utf8mb4
lower_case_table_names=1
skip-host-cache
skip-name-resolve
sql_mode=’STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’
[client]
default-character-set=utf8mb4
