fedora8 下mysql 安装的安装方法

Question

如题所述

Answer 1

我下载的是目前最新的版本mysql-5.0.45-linux-i686.tar.gz
   安装过程：
su 到root 权限。
   #tar -zvxf mysql-5.0.45-linux-i686.tar.gz
   #mv mysql-5.0.45/ /usr/local/mysql
   #cd /usr/local/mysql
   #groupadd mysql
   #useradd -g mysql mysql
   #chown -R mysql .
   #chgrp -R mysql .
   #scripts/mysql_install_db --user=mysql
   #chown -R root .
   #chown -R mysql data
   #bin/mysqld_safe --user=mysql
   按照官方文档说这就应该能启动了，可是报错如下：
   
nohup: ignoring input and redirecting stderr to stdout
   Starting mysqld daemon with databases from /var/lib/mysql
   STOPPING server from pid file /var/run/mysqld/mysqld.pid
   071112 00:22:06  mysqld ended
查看日志：
＃less /var/log/mysqld.log
   其中有一段如下：
   071112  0:22:06 [ERROR] /usr/local/mysql/bin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2)
   071112  0:22:06 [ERROR] Can't start server: can't create PID file: No such file or directory
   071112 00:22:06  mysqld ended
#cd /var/run/
   #ls
   mysqld目录不存在
   #mkdir /var/run/mysqld
   #cd /var/run/mysqld
   创建文件mysqld.pid
   #touch mysqld.pid
   #cd..
   #chown -R mysql mysqld .
#cd /usr/local/mysql/
   #bin/mysqld_safe --user=mysql
   nohup: ignoring input and redirecting stderr to stdout
   Starting mysqld daemon with databases from /var/lib/mysql
能正常启动
#bin/mysqladmin -u root password root
又出错
[root@localhost mysql]# bin/mysqladmin -u root password root
   bin/mysqladmin: connect to server at 'localhost' failed
   error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
   Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
[root@localhost mysql]# bin/mysql -u root -p
   Enter password:
   ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
分析：是/tmp/mysql.sock 不存在
   # cd /var/lib/mysql/
   ibdata1      ib_logfile0  ib_logfile1  mysql/       mysql.sock   test/
   由于mysql 默认的mysql.sock 是在/var/lib/mysql/mysql.sock,
创建符号连接：
   # ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
   # bin/mysql -u root
   Welcome to the MySQL monitor.  Commands end with ; or /g.
   Your MySQL connection id is 1
   Server version: 5.0.45 MySQL Community Server (GPL)
Type 'help;' or '/h' for help. Type '/c' to clear the buffer.
mysql
修改root 密码
   #cd /usr/local/mysql/
   #bin/mysqladmin -u root -p password yourpassword
一切ok.
   一切ok...
