linux下免安装版本mysql5.5 配置

进入/usr/local

#cd /usr/local

下载

#wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.39-linux2.6-x86_64.tar.gz

#解压

tar zxvf mysql-5.5.39-linux2.6-x86_64.tar.gz

#软链

ln -s mysql-5.5.39-linux2.6-x86_64 mysql

cd mysql

#授权

groupadd mysql

useradd -g mysql mysql

chown -R mysql .

chgrp -R mysql .

用mysql_install_db创建MySQL授权表初始化

scripts/mysql_install_db --user=mysql

chown -R mysql data

复制配置文件至etc

#cp /usr/local/mysql/support-files/my-huge.cnf /etc/my.cnf

启动

#bin/mysqld_safe --user=mysql &

### 启动时如果报了 mysqld_safe mysqld from pid file /usr/local/mysql/data/XXXX.pid ended

解决方案是：在配置文件中加入

user=root

datadir=/usr/local/mysql/data

[mysqld]
user =root
port = 3306
socket = /tmp/mysql.sock
datadir=/usr/local/mysql/data

### Starting mysqld daemon with databases from /usr/local/mysql/var 表示正常启动

注：如果任然报这个错重新执行一下

#scripts/mysql_install_db --user=mysql

设置root密码。默认安装密码为空

#/usr/local/mysql/bin/mysqladmin -uroot password yourpassword

拷贝编译目录的一个脚本，设置开机自动启动

cp support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod  /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig --level  mysqld on

ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

启动mysqld服务
#service mysqld start

查看3306端口是否打开。要注意在防火墙中开放该端口
#netstat -atln
