MySQL源码编译安装

创建MySQL所需目录

mkdir /usr/local/mysql
mkdir /usr/local/mysql/etc
mkdir /usr/local/mysql/database

创建MySQL使用的用户和组

useradd mysql

检查编译环境，在检查完成后可通过“echo $?”命令检查是否有错误，当输入结果为0是表示没有错误

cd mysql
./configure --prefix-/usr/local/mysql --sysconfdir=/usr/local/mysql/etc \
--localstatedir=/usr/local/mysql/database --with-character=utf8

编译、安装MySQL

make & make install

安装mysql、test 和information_schema数据库

cd /usr/local/mysql/
./bin/mysql_install_db --user=mysql

建立MySQL配置文件

cd /usr/local/mysql/
cp /usr/local/mysql/share/mysql/my-huge.cnf /etc/my.cnf
cp /usr/local/mysql/share/mysql.server /etc/rc.d/init.d/mysqld
chown -R mysql:mysql /usr/local/mysql/database/
chown -R mysql:mysql /usr/local/mysql/lib/
./bin/mysql_safe --user=mysql &

增加MySQL服务、启动服务并设置为下次启动自动加载

chkconfig --add mysqld
service mysqld restart
chkconfig mysqld onn

将MySQL相关命令复制到/sbin目录

cp /usr/local/mysql/bin/* /sbin

使用mysqladmin创建MySQL管理员及密码

mysqladmin -u root password abc123
