#进入到拷贝目录 解压文件
cd /appcom/com/
tar zxvf mysql-5.5.11-linux2.6-x86_64.tar.gz

#删除压缩文件
rm mysql-5.5.11-linux2.6-x86_64.tar.gz

#为了方便重命名文件
mv mysql-5.5.11-linux2.6-x86_64  mysql

#到mysql目录下 执行安装命令
scripts/mysql_install_db --user=appcom  --basedir=/appcom/com/mysql --datadir=/appcom/com/mysql/data
    
#修改配置文件

#mysql下面如果没有my.cnf 拷贝一份
