1.1二進制包安裝MySQL數據庫

1.1.1 安裝前準備(規范)

[root@Mysql_server ~]# mkdir -p /home/zhurui/tools? ##創建指定工具包存放路徑

[root@Mysql_server ~]# wget http://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.5/mysql-5.5.32-linux2.6-x86_64.tar.gz? ##下載二進制包

[root@Mysql_server tools]# tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz? ##解壓Mysql包

[root@Mysql_server tools]# useradd -s /sbin/nologin -M mysql? ##創建mysql用戶

[root@Mysql_server tools]# id mysql

uid=501(mysql) gid=501(mysql) groups=501(mysql)

[root@Mysql_server ~]# mkdir /application/

[root@Mysql_server home]# mv /home/zhurui/tools/mysql-5.5.32-linux2.6-x86_64 /application/mysql-5.5.32

[root@Mysql_server tools]# ll /application/

drwxr-xr-x. 13 root root 4096 Dec 13 14:31 mysql-5.5.32

[root@Mysql_server tools]# ln -s /application/mysql-5.5.32/ /application/mysql? ##設置軟鏈接

[root@Mysql_server tools]# ll /application/

drwxr-xr-x.? 3 root root? 4096 Dec 13 14:31 support-files

1.1.2 初始化數據庫

[root@Mysql_server tools]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql? ##初始化數據庫

Installing MySQL system tables...

OK

Filling help tables...

OK

[root@Mysql_server tools]# ll /application/mysql/data/? ##查看初始化結果

total 12

drwx------. 2 mysql root? 4096 Dec 13 14:45 mysql

drwx------. 2 mysql mysql 4096 Dec 13 14:45 performance_schema

drwxr-xr-x. 2 mysql root? 4096 Dec 13 14:31 test

1.1.3 授權Mysql管理數據庫文件

[root@Mysql_server ~]# chown -R mysql.mysql /application/mysql/

[root@Mysql_server ~]# ll /application/mysql

lrwxrwxrwx. 1 mysql mysql 26 Dec 13 14:39 /application/mysql -> /application/mysql-5.5.32/

1.1.4 生成Mysql配置文件

[root@Mysql_server tools]# \cp /application/mysql/support-files/my-small.cnf /etc/my.cnf

1.1.5 配置啟動Mysql

[root@Mysql_server tools]# sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe /application/mysql/support-files/mysql.server

[root@Mysql_server tools]# cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld? ##將生成的啟動腳本拷貝到init.d目錄下

[root@Mysql_server tools]# chmod +x /etc/init.d/mysqld

1.1.6 啟動Mysql

[root@Mysql_server tools]# lsof -i :3306? ##查詢Mysql服務是否開啟

[root@Mysql_server tools]#

[root@Mysql_server tools]# /etc/init.d/mysqld start? ##啟動Mysql服務

Starting MySQL.... SUCCESS!

[root@Mysql_server tools]# lsof -i :3306

COMMAND? PID? USER? FD? TYPE DEVICE SIZE/OFF NODE NAME

mysqld? 2235 mysql? 10u? IPv4? 22761? ? ? 0t0? TCP *:mysql (LISTEN)

[root@Mysql_server tools]#

1.1.7 配置環境變量

方法1：

[root@Mysql_server tools]# cp /application/mysql/bin/* /usr/local/sbin/ ##方法1

方法2：

[root@Mysql_server tools]# tail -1 /etc/profile

PATH="/application/mysql/bin:$PATH"? ##尾部添加如下行

[root@Mysql_server tools]# source /etc/profile? ? ##使得配置生效

1.1.8 設置及更改密碼

[root@Mysql_server tools]# mysqladmin -uroot password 123456

[root@Mysql_server tools]# mysqladmin -uroot -p123456 password zhurui

2.1 數據庫管理

[root@Mysql_server tools]# mysql -uroot -p

Enter password:

Query OK, 1 row affected (0.02 sec)

mysql> delete from mysql.user where user="root" and host="Mysql\_server";

Query OK, 1 row affected (0.00 sec)

mysql> select user,host from mysql.user;? ##將無用用戶刪除以后，查看用戶列表

mysql> flush privileges;? ##最后使得權限生效
