1、系統環境 CentOS 6.8_X64
2、需要的軟件mirrors-alisql-master.zip 以及需要的依賴包centos-release-scl devtoolset-4-gcc-c++ devtoolset-4-gcc ncurses-devel openssl-devel bison git cmake
3、安裝需要的依賴軟件包
yum -y install centos-release-scl devtoolset-4-gcc-c++ devtoolset-4-gcc ncurses-devel openssl-devel bison git cmake
4、下載 mirrors-alisql-master.zip
https://github.com/alibaba/AliSQL
5、解壓mirrors-alisql-master.zip
unzip mirrors-alisql-master.zip
6、創建Mysql用戶組和用戶,及數據庫存放目錄:
mkdir -p /usr/local/mysql
mkdir -p /usr/local/mysql/tmp
mkdir -p /var/log/mysql
groupadd mysql
useradd mysql -g mysql -M -s /sbin/nologin
chown -R mysql.mysql /usr/local/mysql
chown -R mysql.mysql /var/log/mysql
7、編譯安裝
cd alisql

scl enable devtoolset-4 bash #在配置前,要先設置下環境變量,這樣才能用到 devtoolset-4 套裝里的gcc
make -j4 && make install #-j4 表示開 4 個并發編譯進程,加速編譯,根據機器 CPU 核數調整,一般是 CPU 核數 + 1
8、編輯配置文件

pid-file = /usr/local/mysql/mysql.pid
chown mysql.mysql /etc/my.cnf
chmod 600 /etc/my.cnf
9、初始化數據庫:(初始化的時候要注意,會生成一個root的隨機密碼,后面登錄會用到)
chmod 777 scripts/mysql_install_db
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --defaults-file=/etc/my.cnf
10、設置環境變量
vim /etc/profile
export PATH=$PATH:/usr/local/mysql/bin:/usr/local/mysql/lib
11、復制 mysql 服務啟動配置文件
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod a+x /etc/init.d/mysqld
12、啟動數據庫進程
service mysqld start
13、修改root密碼,設置遠程登錄
mysql -u root
AliSQL [mysql]>use mysql;
AliSQL [mysql]>select host, user from user;
AliSQL [mysql]>update user set password=PASSWORD('rootoo')where user='root';
AliSQL [mysql]>update user set host = '%' where user = 'root'; #授權遠程登錄用戶名為root,如果報錯,ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY',不予理會
AliSQL [mysql]>flush privileges;
AliSQL [mysql]>grant all on . to "root"@"172.30.41.72" identified by "123456"; #授權172.30.41.72以root用戶遠程登錄訪問數據庫,root密碼為123456
AliSQL [mysql]>grant all on . to "root"@"%" identified by "123456"; #授權所有ip都可以以root用戶遠程登錄訪問數據庫,root密碼為123456
AliSQL [mysql]>grant all on . to "root"@"localhost" identified by "123456"; #授權localhost以root用戶遠程登錄訪問數據庫,root密碼為123456
AliSQL [mysql]>select user from user; #查看所有用戶
14、重啟mysql
service mysqld restart
chkconfig mysqld on
15、下載phpMyAdmin
wget https://files.phpmyadmin.net/phpMyAdmin/4.7.0/phpMyAdmin-4.7.0-all-languages.zip
16、解壓phpMyAdmin-4.7.0-all-languages.zip
unzip phpMyAdmin-4.7.0-all-languages.zip
17、打開libraries下的config.default.php文件,依次找到下面各項,按照說明配置即可:
a.訪問網址
$cfg['pmaabsoluteuri'] = '192.168.1.5';這里填寫phpmyadmin的訪問網址
b.mysql主機信息
$cfg['servers'][$i]['host'] = 'localhost'; // mysql hostname or ip address
填寫localhost或mysql所在服務器的ip地址,如果mysql和該phpmyadmin在同一服務器,則按默認localhost
$cfg['servers'][$i]['port'] = ''; // mysql port - leave blank for default port
mysql端口,如果是默認3306,保留為空即可
c.mysql用戶名和密碼
$cfg['servers'][$i]['user'] = 'root'; // mysql user訪問phpmyadmin使用的mysql用戶名
fg['servers'][$i]['password'] = 'rootoo'; // mysql password (only needed對應上述mysql用戶名的密碼
d.認證方法
$cfg['servers'][$i]['auth_type'] = 'http';
在此有四種模式可供選擇,cookie,http,http,config
config方式即輸入phpmyadmin的訪問網址即可直接進入,無需輸入用戶名和密碼,是不安全的,不推薦使用。
當該項設置為cookie,http或http時,登錄phpmyadmin需要數據用戶名和密碼進行驗證,,具體如下:
php安裝模式為nginx/apache,可以使用http和cookie;
php安裝模式為cgi,可以使用cookie
e.短語密碼(blowfish_secret)的設置
$cfg['blowfish_secret'] = '';
如果認證方法設置為cookie,就需要設置短語密碼,但是不能留空,否則會在登錄phpmyadmin時提示錯誤
f.配置
1、打開 /libraries/config.default.php文件(舊版本是根目錄下的config.inc.php文件),用寫字板(不要用記事本,這是utf8編碼)進行編輯,按照說明配置即可。
2、查找 $cfg['pmaabsoluteuri']=‘'; // 修改為你將上傳到空間的phpmyadmin的網址
如:$cfg['pmaabsoluteuri'] =‘http: // 網站域名/phpmyadmin/';
3、查找 $cfg['servers'][$i]['host'] =‘localhost'; // 通常用默認,也有例外,可以不用修改
4、查找 $cfg['servers'][$i]['auth_type'] =‘config'; // 在自己的機子里調試用config;如果在網絡上的空間用cookie.
18、http://192.168.1.5/phpMyAdmin/ 輸入用戶名root密碼rootoo后,訪問正常
常見的錯誤:#2002 - Permission denied — 服務器沒有響應(或本地服務器的套接字沒有正確設置)。
報錯原因:如果未指定指定主機名或指定了特殊的主機名localhost,將使用Unix套接字。
Unix套接字默認為/tmp/mysql.sock,如果沒有配置這樣的套接字文件或者配置不正確,所以自然是連接失敗了。
解決方法:$cfg['servers'][$i]['host'] =‘localhost';改為$cfg['servers'][$i]['host'] =‘127.0.0.1';
