MYSQL安装

安装cmake:

1. tar zxvf cmake-2.8.4.tar.gz

2. cd cmake-2.8.4

3. ./configure --prefix=/usr/local/cmake

4. make && make install

安装mysql5.5.13

• groupadd mysql //所以在这里我们要建一个msyql的用户和组

useradd -g mysql mysql -s /usr/sbin/nologin mkdir /usr/local/mysql //创建目录 mkdir /usr/local/mysql/data

进入mysql-5.5.13的解压目录：

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql && make && make install

进入mysql的安装目录/usr/local/mysql下:

• scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql //初始化mysql数据库

cp support-files/my-medium.cnf /usr/local/mysql/my.cnf //copy配置文件 chown -R mysql:mysql /usr/local/mysql //更改权限

vi /usr/local/mysql/my.cnf //加上以下内容

[mysqld]

basedir = /usr/local/mysql

datadir = /usr/local/mysql/data

log-error = /usr/local/mysql/mysql_error.log

pid-file = /usr/local/mysql/mysql.pid

user = mysql

tmpdir = /tmp

启动mysql bin/mysqld_safe --user=mysql & 或使用下列命令把mysql添加为系统服务。

• cd /usr/local/mysql/support-files/

cp ./mysql.server /etc/init.d/mysqld /etc/init.d/mysqld start

高版本的mysql可以兼容低版本的。
