一、准备环境
1、安装确保以下系统相关库文件
gcc gcc-c++ autoconf automake zlib* libxml* ncurses-devel libmcrypt* libtool*(libtool-ltdl-devel*)
# yum –y install gcc gcc-c++ autoconf automake zlib* libxml* ncurses-devel libmcrypt* libtool*
2、建立mysql安装目录及数据存放目录
# mkdir /usr/local/mysql
# mkdir /var/mysqldata
3、创建用户和用户组
# groupadd mysql
# useradd -g mysql mysql
4、赋予数据存放目录权限
# chown mysql.mysql –R /var/mysqldata/
5、安装cmake
mysql5.5以后是通过cmake来编译的
通过以下路径下载cmake-2.8.4.tar.gz,也可在网站进行下载
# wget
# tar zxvf cmake-2.8.4.tar.gz
# cd cmake-2.8.4
# ./configure
# make && make install
二、安装MySQL 5.5.13
1、获取解压mysql-5.5.13.tar.gz
通过以下路径下载mysql-5.5.13.tar.gz,也可在官网网站进行下载
# wget
# tar zxvf mysql-5.5.13.tar.gz
# cd mysql-5.5.13
2、编译mysql-5.5.13
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/var/mysqldata/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/var/mysqldata \
-DMYSQL_USER=mysql \
-DMYSQL_TCP_PORT=3306
# make
# make install
3、复制配置文件
# cp support-files/my-medium.cnf /etc/my.cnf
4、初始化数据库
执行前需赋给scripts/mysql_install_db文件执行权限
# chmod 755 scripts/mysql_install_db
# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ \
--datadir=/var/mysqldata/
注:basedir:mysql安装路径 datadir:数据库文件储存路径
5、设置mysqld的开机启动
# cp support-files/mysql.server /etc/init.d/mysql
# chmod 755 /etc/init.d/mysql
# chkconfig mysql on
6、为MySQL配置环境变量
将mysql的bin目录加到PATH中,有利于以后管理和维护,在/etc/profile中加入myslq/bin,同时增加两个别名方便操作:
# export PATH=/usr/local/mysql/bin:$PATH
# alias mysql_start="mysqld_safe &"
# alias mysql_stop="mysqladmin –u root -p shutdown"
7、启动mysql服务
# /etc/init.d/mysql start
启动完成之后用ps -ef |grep mysql 命令查看是否启动
8、登陆mysql
# mysql -u root –p
三、MySQL标准设置
1、为root帐户设置初始密码
# /usr/local/mysql/bin/mysqladmin -u root password 'new-password'
或者限制只能通过本机登陆
# /usr/local/mysql/bin/mysqladmin -u root -h ‘hostname’ password 'new-password'
2、删除本机匿名连接的空密码帐号
本机登录mysql
mysql>use mysql; //选择默认数据库mysql
mysql>update user set password=’root123’ where user = '127.0.0.1';
mysql>delete from user where password="";//不允许root密码为空
mysql>flush privileges;
mysql>quit
容许root用户是远程登录
对于root账号,如果考虑安全应该新建其他账号用于远程登录,,root账号可以不必开启远程登录。不过对于一般使用,没有太多安全需求,允许root用户远程登录可以方便管理,毕竟使用专用管理软件的图形界面在操作方面要方便的多。
3、设置MySQL远程连接
1) mysql 数据库端设置
# /mysql -u root -p //进入数据库
mysql>use mysql
mysql>select user,password,host from user;
mysql>update user set host = '192.168.%' where user = '127.0.0.1';
mysql>grant all privileges on *.* to root@'%' identified by "root123";//给以root@ip登录的远程连接赋予权限,能够连接数据库。远程无法连接的常见问题原因。并把远程登录用户的密码设置为root
mysql> flush privileges;
mysql>quit
2) Windows下MySQL客户端
MySQL官方GUI客户端:

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
