MYSQL安装过程及报错信息

MYSQL安装步骤:

    #下载,解压源码包,移动到指定目录:

    wget http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-x86_64-icc-glibc23.tar.gz

    tar zxvf mysql-5.1.40-linux-x86_64-icc-glibc23.tar.gz

    mv mysql-5.1.40-linux-x86_64-icc-glibc23.tar.gz /usr/local/mysql

   #新建数据库存储路径:

    mkdir -p /data/mysql

    #创建mysql的管理用户:

     useradd -s /sbin/nologin mysql

    chown -R /usr/local/mysql

    #拷贝mysql实例和到开机启动服务

    cp /usr/local/mysql/data/support-files/my-medium.cnf /etc/my.cnf

    cp /usr/local/mysql/data/support-files/mysql.server /etc/init.d/mysqld

    #修改上述两个配置文件

    vi /etc/my.cnf

        log-bin=mysql-bin/server-id =1/binlog_format=mixed三个注释掉,后面mysql主从时候用到

     #socket,使用socket通信,关掉

    后面添加一行skip-network关闭3306端口,外网检测不到

  vi /etc/init.d/mysqld

    basedir=/usr/local/mysql

    datadir=/usr/local/myslq/data/mysql

  #将mysqld添加到chkconfig服务启动项

    chkconfig --add mysqld

    chkconfig mysqld on(chkconfig查看已添加哪些启动服务;chkconfig --del xx删除)

  #启动mysqld服务

    service mysqld start或者/etc/init.c/mysqld start

  #检验是否成功:

    ps aux |grep mysql或者netstat -npl |grep 3306

报错:

# ./script/mysql_install_db --user=mysql --datadir=/data/mysql 在对mysql初始化时候报错

    FATAL ERROR: Could not find ./bin/my_print_defaults
    解决方法:首先没有指定datadir的绝对路径,再没有指定basedir路径

    ./script/mysql_install_db --user=mysql --datadir=/usr/local/data/mysql --basedir=/usr/local/mysql

    echo $?查看输出是否正确:0正确,1有错误

# ./script/mysql_install_db --user=mysql --datadir=/usr/local/data/mysql --basedir=/usr/local/mysql初始化时报错:

    ERROR: 1  Can't create/write to file '/usr/local/mysql/data/mysql/mysql/db.MYI' (Errcode: 13)

    解决方法:还是/usr/local/mysql的权限问题

        chown -R mysql:mysql /usr/local/mysql

        echo $?  0和两个OK

#/etc/init.d/mysqld start启动mysqld服务时

    报错:Starting MySQL.. ERROR! Manager of pid-file quit without updating file.

    解决方法:重新初始化 ./script/mysql_install_db --user=mysql

    结果:SUCCESS
