Linux 安装 mysql5.5.19
在官网上下载mysql-5.5.19-linux2.6-i686.tar.gz压缩包,此包解压后为编译好的文件,不需要咱们自己编译、安装,直接修改配置即可用。 1、将 mysql-5.5.19-linux2.6-x86_64.tar.gz拷贝至 /opt 目录 2、解压 # tar -zxvfmysql-5.5.19-linux2.6-i686.tar.gz -C
在官网上下载mysql-5.5.19-linux2.6-i686.tar.gz压缩包,此包解压后为编译好的文件,不需要咱们自己编译、安装,直接修改配置即可用。
1、将
2、解压
# tar -zxvfmysql-5.5.19-linux2.6-i686.tar.gz -C /usr/local/ ;
注意:解压到/usr/local/ 非常重要
3.将
注意:现在mysql的目录为:/usr/local/mysql(如果放在其他目录,安装问题会很多)
4、建立数据库的用户组和用户
# groupaddmysql
# useradd -gmysql mysql
5、将mysql启动脚本mysql.server复制到/etc/rc.d/init.d目录中,命名为mysql;
# cpsupport-files/mysql.server /etc/rc.d/init.d/mysql
7、复制mysql配置文件my-medium.cnf到/etc/目录中,命名为my.cnf;
# cpsupport-files/my-medium.cnf /etc/my.cnf
8、修改mysql目录权限;
# chown -Rroot
# chgrp -Rmysql/usr/local/mysql
# chown -Rmysql/usr/local/mysql/data
9、生成mysql系统数据库。执行/usr/local/mysql/scripts/mysql_install_db安装授权表.
#/usr/local/mysql/scripts/mysql_install_db--user=mysql&
10、启动mysql服务.运行/usr/local/mysql/bin/mysqld_safe
#/usr/local/mysql/bin/mysqld_safe--user=mysql&
如果出现:Starting mysqld daemon withdatabase from /usr/local/mysql/data代表正常启动mysql服务器。
11、启动mysql服务
#/etc/rc.d/init.d/mysql start
12、启动mysql
#/usr/local/mysql/bin/mysql
出现mysql>
到此,mysql就搞定了,你可以操作数据库,可以修改管理员密码了……
启动mysql注意问题:
(1)要启动mysql必须先启动mysql_safe服务(上边第10步)。
# /usr/local/mysql/bin/mysqld_safe--user=mysql&
# /etc/rc.d/init.d/mysql start
(3)然后启动mysql
# /usr/local/mysql/bin/mysql
二、登录mysql方法:
(1)如果你已经在/usr/local/mysql/bin目录
执行:#./mysql
如果root用户设置了密码
执行:
./mysql -u root-p
输入mysql root的密码,然后回车。
(2)如果你在其他目录
执行:# /usr/local/mysql/bin/mysql
如果root用户设置了密码
执行:
/usr/local/mysql/bin/mysql-u
root -p
输入mysql root的密码,然后回车。
三、Linux 下 让mysql自动启动
在MySQL安装程序的解压包/usr/local/mysql/support-files有一个叫myslq.server的启动脚本程序。把它复制到/etc/rc.d/init.d目录里面:
# cd /etc/rc.d/init.d
# cp /usr/local/mysql/support-files/mysql.server mysql
接着把它的属性改为“x”(executable,可执行)
# chmod +x mysql
最后,运行chkconfig把MySQL添加到你系统的启动服务组里面去。
执行chkconfig --add mysql
四、修改root用户密码:
/usr/local/mysql/bin/mysqladmin -u root password'new-password'
/usr/local/mysql/bin/mysqladmin -u root -h test11 password'new-password'
