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/

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

[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
