scl enable devtoolset-4 bash #在配置前,要先设置下环境变量,这样才能用到 devtoolset-4 套装里的gcc
make -j4 && make install #-j4 表示开 4 个并发编译进程,加速编译,根据机器 CPU 核数调整,一般是 CPU 核数 + 1
8、编辑配置文件

pid-file = /usr/local/mysql/mysql.pid
chown mysql.mysql /etc/my.cnf
chmod 600 /etc/my.cnf
9、初始化数据库:(初始化的时候要注意,会生成一个root的随机密码,后面登录会用到)
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、设置环境变量
vim /etc/profile
export PATH=$PATH:/usr/local/mysql/bin:/usr/local/mysql/lib
11、复制 mysql 服务启动配置文件
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod a+x /etc/init.d/mysqld
12、启动数据库进程
service mysqld start
13、修改root密码,设置远程登录
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'; #授权远程登录用户名为root,如果报错,ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY',不予理会
AliSQL [mysql]>flush privileges;
AliSQL [mysql]>grant all on . to "root"@"172.30.41.72" identified by "123456"; #授权172.30.41.72以root用户远程登录访问数据库,root密码为123456
AliSQL [mysql]>grant all on . to "root"@"%" identified by "123456"; #授权所有ip都可以以root用户远程登录访问数据库,root密码为123456
AliSQL [mysql]>grant all on . to "root"@"localhost" identified by "123456"; #授权localhost以root用户远程登录访问数据库,root密码为123456
AliSQL [mysql]>select user from user; #查看所有用户
14、重启mysql
service mysqld restart
chkconfig mysqld on
15、下载phpMyAdmin
wget https://files.phpmyadmin.net/phpMyAdmin/4.7.0/phpMyAdmin-4.7.0-all-languages.zip
16、解压phpMyAdmin-4.7.0-all-languages.zip
unzip phpMyAdmin-4.7.0-all-languages.zip
17、打开libraries下的config.default.php文件,依次找到下面各项,按照说明配置即可:
a.访问网址
$cfg['pmaabsoluteuri'] = '192.168.1.5';这里填写phpmyadmin的访问网址
b.mysql主机信息
$cfg['servers'][$i]['host'] = 'localhost'; // mysql hostname or ip address
填写localhost或mysql所在服务器的ip地址,如果mysql和该phpmyadmin在同一服务器,则按默认localhost
$cfg['servers'][$i]['port'] = ''; // mysql port - leave blank for default port
mysql端口,如果是默认3306,保留为空即可
c.mysql用户名和密码
$cfg['servers'][$i]['user'] = 'root'; // mysql user访问phpmyadmin使用的mysql用户名
fg['servers'][$i]['password'] = 'rootoo'; // mysql password (only needed对应上述mysql用户名的密码
d.认证方法
$cfg['servers'][$i]['auth_type'] = 'http';
在此有四种模式可供选择,cookie,http,http,config
config方式即输入phpmyadmin的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。
当该项设置为cookie,http或http时,登录phpmyadmin需要数据用户名和密码进行验证,,具体如下:
php安装模式为nginx/apache,可以使用http和cookie;
php安装模式为cgi,可以使用cookie
e.短语密码(blowfish_secret)的设置
$cfg['blowfish_secret'] = '';
如果认证方法设置为cookie,就需要设置短语密码,但是不能留空,否则会在登录phpmyadmin时提示错误
f.配置
1、打开 /libraries/config.default.php文件(旧版本是根目录下的config.inc.php文件),用写字板(不要用记事本,这是utf8编码)进行编辑,按照说明配置即可。
2、查找 $cfg['pmaabsoluteuri']=‘'; // 修改为你将上传到空间的phpmyadmin的网址
如:$cfg['pmaabsoluteuri'] =‘http: // 网站域名/phpmyadmin/';
3、查找 $cfg['servers'][$i]['host'] =‘localhost'; // 通常用默认,也有例外,可以不用修改
4、查找 $cfg['servers'][$i]['auth_type'] =‘config'; // 在自己的机子里调试用config;如果在网络上的空间用cookie.
18、http://192.168.1.5/phpMyAdmin/ 输入用户名root密码rootoo后,访问正常
常见的错误:#2002 - Permission denied — 服务器没有响应(或本地服务器的套接字没有正确设置)。
报错原因:如果未指定指定主机名或指定了特殊的主机名localhost,将使用Unix套接字。
Unix套接字默认为/tmp/mysql.sock,如果没有配置这样的套接字文件或者配置不正确,所以自然是连接失败了。
解决方法:$cfg['servers'][$i]['host'] =‘localhost';改为$cfg['servers'][$i]['host'] =‘127.0.0.1';
