fedora8 下mysql 安装的安装方法,安装mysql8.0.19

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.

修改root 密码 #cd /usr/local/mysql/ #bin/mysqladmin -u root -p password yourpassword

一切ok. 一切ok...
