二进制包安装MySQL数据库

1.1二进制包安装MySQL数据库

1.1.1 安装前准备(规范)

[root@Mysql_server ~]# mkdir -p /home/zhurui/tools ##创建指定工具包存放路径
[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 ##下载二进制包
[root@Mysql_server tools]# tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz ##解压Mysql包
[root@Mysql_server tools]# useradd -s /sbin/nologin -M mysql ##创建mysql用户
[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/
total 4
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 ##设置软链接
[root@Mysql_server tools]# ll /application/
total 4
lrwxrwxrwx. 1 root root 26 Dec 13 14:39 mysql -> /application/mysql-5.5.32/
drwxr-xr-x. 13 root root 4096 Dec 13 14:31 mysql-5.5.32
[root@Mysql_server tools]# ll /application/mysql/
total 76

drwxr-xr-x. 4 root root 4096 Dec 13 14:31 sql-bench
drwxr-xr-x. 3 root root 4096 Dec 13 14:31 support-files

1.1.2 初始化数据库

[root@Mysql_server tools]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql ##初始化数据库
Installing MySQL system tables...
OK
Filling help tables...
OK
[root@Mysql_server tools]# ll /application/mysql/data/ ##查看初始化结果
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 授权Mysql管理数据库文件

[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 配置启动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 ##将生成的启动脚本拷贝到init.d目录下
[root@Mysql_server tools]# chmod +x /etc/init.d/mysqld

1.1.6 启动Mysql

[root@Mysql_server tools]# lsof -i :3306 ##查询Mysql服务是否开启
[root@Mysql_server tools]#
[root@Mysql_server tools]# /etc/init.d/mysqld start ##启动Mysql服务
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 配置环境变量

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 设置及更改密码

[root@Mysql_server tools]# mysqladmin -uroot password 123456
[root@Mysql_server tools]# mysqladmin -uroot -p123456 password zhurui

2.1 数据库管理

[root@Mysql_server tools]# mysql -uroot -p
Enter password:
