  • Linux中MySQL5.5解压版普通用户安装

    #查看本机mysql 安装路径

    [hadoop@SY-0134 toolkit]$ rpm -qa|grep -i mysql
    
    [hadoop@SY-0134 toolkit]$ whereis mysql
    
    mysql: /usr/lib/mysql /usr/share/mysql

    环境Centos, 经过检验,上述目录实际没有mysql的安装,只是有一些lib包和帮助语言包。

    #解压mysql-5.5.39-linux2.6-i686.tar.gz 到/lab/mysql5.5目录

     #配置mysql5.5 conf文件

    cp support-files/my-medium.cnf /data/my.cnf

    #修改my.cnf文件,配置Mysql数据存储目录

    在mysqld下面添加:datadir=/lab/mysql5.5/data

    #配置目录用户访问权限:

    [hadoop@SY-0134 mysql5.5]$ scripts/mysql_install_db -user=hadoop
    
    Installing MySQL system tables...
    
    OK
    
    Filling help tables...
    
    OK
    
    To start mysqld at boot time you have to copy
    
    support-files/mysql.server to the right place for your system
    
    PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
    
    To do so, start the server, then issue the following commands:
    
    ./bin/mysqladmin -u root password 'new-password'
    
    ./bin/mysqladmin -u root -h SY-0134 password 'new-password'
    
    Alternatively you can run:
    
    ./bin/mysql_secure_installation
    
    which will also give you the option of removing the test
    
    databases and anonymous user created by default.  This is
    
    strongly recommended for production servers.
    
    See the manual for more instructions.
    
    You can start the MySQL daemon with:
    
    cd . ; ./bin/mysqld_safe &
    
    You can test the MySQL daemon with mysql-test-run.pl
    
    cd ./mysql-test ; perl mysql-test-run.pl

    #设置mysqld服务随服务器启动

    #切换到root用户

    cp support-files/mysql.server /etc/rc.d/init.d/mysqld
    
    chmod 700 /etc/init.d/mysqld
    
    chkconfig --add mysqld
    
    chkconfig -–level 2345 mysqld on

     [root@SY-0134 mysql5.5]# chkconfig --list mysqld

     mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

    #修改/etc/rc.d/init.d/mysqld文件设置,制定Mysql安装目录和数据存储目录

    basedir=/lab/mysql5.5

    datadir=/lab/mysql5.5/data

    #启动mysqld服务

    service mysqld start

    #查看3306端口是否打开。要注意在防火墙中开放该端口

    netstat -atln

    权限放开 ,使得普通用户也能启动mysql服务

    [root@SY-0134 mysql5.5]# chmod a+wrx /etc/init.d/mysqld

    MySQL问题解决:-bash:mysql:command not found

    解决办法,将mysql命令创建软连接到/usr/bin中:

    ln -s /lab/mysql5.5/bin/mysql  /usr/bin
