mysql在linux下的安裝

安裝環境:系統是 centos6.5html

一、下載mysql

    下載地址:http://dev.mysql.com/downloads/mysql/5.6.html#downloadslinux

    下載版本:我這裏選擇的5.6.33,通用版,linux下64位sql

    也能夠直接複製64位的下載地址,經過命令下載:wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz數據庫

二、解壓centos

#解壓
tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
#複製解壓後的mysql目錄
cp -r mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql

三、添加用戶組和用戶bash

#添加用戶組
groupadd mysql
#添加用戶mysql 到用戶組mysql
useradd -g mysql mysql

四、安裝測試

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 #修改啓動腳本 vi /etc/init.d/mysqld #修改項: basedir=/usr/local/mysql/ datadir=/usr/local/mysql/data/mysql #啓動服務 service mysqld start #測試鏈接 ./mysql/bin/mysql -uroot #加入環境變量,編輯 /etc/profile,這樣能夠在任何地方用mysql命令了 export PATH=$PATH:/usr/local/mysql//bin
source /etc/profile #啓動mysql service mysqld start #關閉mysql service mysqld stop #查看運行狀態 service mysqld status

五、錯誤spa

  5.1 sqlyog鏈接時,報1130錯誤,是因爲沒有給遠程鏈接的用戶權限問題code

    解決1:更改 ‘mysql’數據庫‘user’表‘host’項,從‘localhost’改爲‘%’。

use mysql;
select 'host' from user where user='root'; 
update user set host = '%' where user ='root';
flush privileges; 

    解決2:直接受權

      GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;

  5.2 安裝時的一些錯誤

    -bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 沒有那個文件或目錄
    解決: 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
    解決:yum -y install libaio-devel

六、其餘

  6.1 配置環境變量

    vi + /etc/profile

    export PATH=....:/usr/local/mysql/bin
