【mysql】linux下安装mysql

mysql在linux下的安装

1、下载

    下载地址:http://dev.mysql.com/downloads/mysql/5.6.html#downloads

    下载版本:我这里选择的5.6.33,通用版,linux下64位

    也可以直接复制64位的下载地址,通过命令下载: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
    cp -r mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql

 

3、添加用户组和用户

    #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

    #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
