Linux 下 Mysql 源码包安装简述
1.下载
从 www.mysql.com 下载所需的 mysql 版本（源码包）
如 mysql-x.x.xx.tar.gz
2.解压、安装
cd /opt
tar -zxvf mysql-x.x.xx.tar.gz
cd mysql-x.x.xx
./configure --prefix=/opt/mysql-x.x.xx
make;make install clean
3.配置
添加用户
useradd -M -d /dev/null -s /sbin/nologin mysql
初始化 mysql
cd /opt/mysql-x.x.xx/bin
./mysql_install_db
cd ..
chown -R mysql:mysql var
chgrp root var
4.测试
cd /opt/mysql-x.x.xx/bin
启动 mysql
./mysqld_safe &
( 注：早些时期的版本这里是 safe_mysqld )
netstat -an | grep LISTEN | grep 3306
如果看到如下一行
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
就说明安装配置均 OK 了
如果没有这行或在启动 mysql 时报错，则检查 /opt/mysql-x.x.xx/var 下的
主机名.err （这里主机名是指主机的名称，可用 hostname 命令察看）
5.编写启动脚本
echo "#! /bin/sh" > /etc/init.d/mysqld
echo " " >> /etc/init.d/mysqld
echo "case /"/$1/" in" >> /etc/init.d/mysqld
echo " start)" >> /etc/init.d/mysqld
echo " echo /"Starting mysqld/"" >> /etc/init.d/mysqld
echo " /opt/mysql-x.x.xx/bin/mysqld_safe &" >> /etc/init.d/mysqld
echo " ;;" >> /etc/init.d/mysqld
echo " stop)" >> /etc/init.d/mysqld
echo " echo /"Shutting down mysqld/"" >> /etc/init.d/mysqld
echo " killall /opt/mysql-x.x.xx/libexec/mysqld" >> /etc/init.d/mysqld
echo " ;;" >> /etc/init.d/mysqld
echo " restart|reload)" >> /etc/init.d/mysqld
echo " /$0 stop && /$0 start" >> /etc/init.d/mysqld
echo " ;;" >> /etc/init.d/mysqld
echo " *)" >> /etc/init.d/mysqld
echo " echo /"Usage: /$0 {start|stop|restart|reload}/"" >> /etc/init.d/mysqld
echo " exit 1" >> /etc/init.d/mysqld
echo "esac" >> /etc/init.d/mysqld
echo "exit 0" >> /etc/init.d/mysqld
chmod 750 /etc/init.d/mysqld
cd /etc/rc3.d
ln -s ../init.d/mysqld S88mysqld
完成
