fedora8下mysql安裝
fedora8下mysql安裝
記得在fedora7 中按照mysql 的安裝文檔一步步來就行，可在fedora 8 中卻出現了問題，經多方查找原因終於解決，慶祝一下。
我下載的是目前最新的版本mysql-5.0.45-linux-i686.tar.gz
安裝過程：
su 到root 權限。
#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 &
按照官方文檔說這就應該能啓動了，可是報錯如下：
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
查看日誌：
＃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目錄不存在
#mkdir /var/run/mysqld
#cd /var/run/mysqld
創建文件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
能正常啓動
#bin/mysqladmin -u root password root
又出錯
[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/
由於mysql 默認的mysql.sock 是在/var/lib/mysql/mysql.sock,
創建符號連接：
# 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 密碼
#cd /usr/local/mysql/
#bin/mysqladmin -u root -p password yourpassword
一切ok。
