linux下搭建mysql数据库

linux下搭建mysql数据库

1.下载mysql:

http://dev.mysql.com/downloads/mysql/5.6.html#downloads

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz

 

 

 

 

 

2.解压:
#解压
    tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz

 

#复制解压后的mysql目录---拷贝到mysql文件夹下
cp -r mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql

 

3.加用户组和用户
    #添加用户组
    groupadd mysql

#添加用户mysql 到用户组mysql
    useradd -g mysql mysql

 

4、安装
cd /usr/local/mysql/
    mkdir ./data/mysql
    chown -R mysql:mysql ./
    ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql

cp support-files/mysql.server /etc/init.d/mysqld
    chmod 755 /etc/init.d/mysqld
  cp support-files/my-default.cnf /etc/my.cnf
cd /usr/local/mysql
cd support-files/
ls
cp my-default.cnf /etc/my.cnf
y
vi /etc/init.d/mysqld
service mysqld start --启动数据库
chkconfig mysqld on ----开机自启
cd .. ----切换到根目录
./bin/mysql -u root -----给root用户授权

show databases --------显示datebases
set password=password('123456'); -----设置数据库密码为123456
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; ----给每个用户每张表授权为密码为123456的可以登录
flush privileges; -----刷新权限修改操作,让命令赋权生效

 

#修改启动脚本
    vi /etc/init.d/mysqld

    #修改项:
    basedir=/usr/local/mysql/
    datadir=/usr/local/mysql/data/mysql

    #启动服务
    service mysqld start

    #测试连接
    ./mysql/bin/mysql -uroot

    #加入环境变量,编辑 /etc/profile,这样可以在任何地方用mysql命令了
    export PATH=$PATH:/usr/local/mysql//bin
    source /etc/profile
    #启动mysql
    service mysqld start
    #关闭mysql
    service mysqld stop
    #查看运行状态
    service mysqld status

5、错误
  5.1 sqlyog连接时,报1130错误,是由于没有给远程连接的用户权限问题
    解决1:更改 ‘mysql’数据库‘user’表‘host’项,从‘localhost’改成‘%’。
    use mysql;
    select 'host' from user where user='root';
    update user set host = '%' where user ='root';
    flush privileges;
    解决2:直接授权
      GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
  5.2 安装时的一些错误
    -bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 没有那个文件或目录
    解决: yum -y install perl perl-devel
    Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
    解决:yum -y install libaio-devel
6、其他
  6.1 配置环境变量
    vi + /etc/profile
    export PATH=....:/usr/local/mysql/bin
