一、優化部分

1、操作系統參數調優

2、數據庫參數調優

3、防火墻設置等

二、安裝部分

1、創建用戶和組#?groupadd?mysql

#?useradd?-g?mysql?mysql

2、到安裝目錄，解壓安裝文件#cd?/data

#tar?-zxvf?mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz

#mv?mysql-5.7.19-linux-glibc2.12-x86_64?mysql

3、創建數據庫安裝目錄、授權#mkdir??/data/mysql/data?/data/mysql/log

#chown?-R?mysql:mysql?/data/mysql

4、驗證權限#?ls?-l?mysqltotal?52

drwxr-xr-x?2?mysql?mysql?4096?Aug?8?04:06?bin

-rw-r--r--?1?mysql?mysql?17987?Jun?22?22:13?COPYING

drwxr-xr-x?2?mysql?mysql?4096?Aug?8?04:06?docs

slow_query_log?=?1

long_query_time?=?1

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

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

6、安裝數據庫#??yum?-y?install?libaio

#?./bin/mysqld?--initialize?--user=mysql?--basedir=/data/mysql?--datadir=/data/mysql/data?--innodb_undo_tablespaces=3?--explicit_defaults_for_timestamp

7、配置啟動文件cp?support-files/mysql.server?/etc/init.d/mysqld

chkconfig?--add?mysqld

chkconfig?mysqld?on

service?mysqld?start

8、配置環境變量vi?/etc/profile

#for?mysql

mysql_home=/data/mysql

PATH=$PATH:$mysql_home/bin

source?/etc/profile

9、查看默認密碼grep?-i?password?/mysql/log/mysql-error.log

10、初始化密碼mysql?-uroot?-p‘xxxxx‘

SET?PASSWORD=PASSWORD('root');

flush?privileges;

11、數據庫常規啟停#mysqladmin?-uroot?-proot?shutdown

#mysqld_safe?--defaults-file=/etc/my.cnf?&

#ps?-ef|grep?mysql
