linux安装mysql

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<br>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、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

出现错误:
FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:
初始化mysql数据库提示缺少Data:dumper模块解决方法
Data::Dumper 
解决方法 :安装autoconf库
命令:yum-y install autoconf //此包安装时会安装Data:Dumper模块

运行安装mysql 报错

[root@localhost mysql-mult]# ./scripts/mysql_install_db  --defaults-file=conf/3306my.cnf

FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db:
Data::Dumper

解决方法 :安装autoconf库
命令:yum-y install autoconf

root@bigdata-159:/usr/local/mysql# ./bin/mysqld -- defaults-file=/etc/my.cnf --initialize --user=mysql
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

解决方法:

[root@example.com data]# yum install -y libaio  //安装后在初始化就OK了

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;
