HomeDatabaseMysql TutorialUbuntu12.04中编译Mysql5.6.17_MySQL

Ubuntu

1.安装Mysql

(1)安装编译源码需要的包
sudo apt-get install make cmake gcc g++ bison libncurses5-dev

(2)下载并解压缩
wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.17.tar.gz
tar -zxvf mysql-5.6.17.tar.gz
cd mysql-5.6.17

(3)编译安装
编译配置:

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITHOUT_FEDERATED_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock -DMYSQL_TCP_PORT=3306 -DCOMPILATION_COMMENT="lq-edition"-DENABLE_DTRACE=1 -DOPTIMIZER_TRACE=1 -DWITH_DEBUG=1

编译:
make

安装:
sudo make install


2.配置MySQL

(1)新建运行Mysql的用户和组
sudo groupadd mysql
sudo useradd -g mysql mysql

(2)设置Mysql安装目录的权限
cd /usr/local/mysql
sudo chown -R mysql:mysql ./

(3)建立配置文件
cp support-files/my-default.cnf /etc/my.cnf
sudo chown mysql:mysql /etc/my.cnf

修改配置文件:
sudo vi /etc/my.cnf
[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock

[mysqld]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
basedir = /usr/local/mysql
datadir  = /usr/local/mysql/data

(4)初始化数据库
sudo scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/

(5)启动mysql服务

方法1:
直接启动
bin/mysqld_safe &
检查MySQL服务是否启动:
ps -ef |grep mysql

方法2:
通过服务启动
添加服务,复制启动脚本到/etc/init.d目录:
cp support-files/mysql.server /etc/init.d/mysql
设置文本的权限:
sudo chmod 755 /etc/init.d/mysql
启动:
sudo /etc/init.d/mysql start
(关闭mysql服务:sudo /etc/init.d/mysql stop)
或者
sudo service mysql start
(关闭mysql服务:sudo service mysql stop)

检查MySQL服务是否启动:
ps -ef |grep mysql

(6)配置环境变量
为了直接调用mysql,需要将mysql的bin目录加入PATH环境变量。
编辑/etc/profile文件:
sudo vim /etc/profile
在文件最后 添加如下两行:
PATH=$PATH:/usr/local/mysql/bin
export PATH
关闭文件,运行下面的命令,让配置立即生效:
source /etc/profile

(7)修改root密码(因为默认密码为空)
mysql -h127.0.0.1 -uroot -p
update mysql.user set password=password("mysqldba") where user='root';
flush privileges;

测试一下:

select now(),user(),version();
show databases;

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.
