解决redhat as4 下mysql登录找不到mysql.sock错误

c35r0z28nw

　　今天运维的重做了个虚机环境用来部署我们项目的测试环境，装redhat as4.由于项目中用的mysql5，系统自带mysql4.1.20应该先去掉。
　　
　　#rpm -qa|grep mysql
　　找到若干个包
　　mysqlclient10-3.23.58-4.RHEL4.1
mysql-4.1.20-1.RHEL4.1
　　
　　# rpm -e mysql-4.1.20-1.RHEL4.1
error: Failed dependencies:
        libmysqlclient.so.14 is needed by (installed) cyrus-sasl-sql-2.1.19-5.EL4.i386
　　
# rpm -e cyrus-sasl-sql-2.1.19-5.EL4.i386
　　
# rpm -e mysql-4.1.20-1.RHEL4.1
　　
# rpm -e mysqlclient10-3.23.58-4.RHEL4.1
　　
# rpm -qa|grep mysql
　　
　　没有内容，证明已经删除干净
　　安装mysql5
　　
　　# rpm -i MySQL-server-5.5.10-1.rhel4.i386.rpm
　　
　　#rpm -i MySQL-client-5.5.10-1.rhel4.i386.rpm
　　
　　完成登录msyql5，这时候出问题了
　　
　　# mysqladmin -u root password 'root'
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!
　　
　　# /etc/rc.d/init.d/mysql status
MySQL is not running                                       [FAILED]
　　
# /etc/rc.d/init.d/mysqld status
-bash: /etc/rc.d/init.d/mysqld: No such file or directory
　　
# service mysql start
Starting MySQL...                                          [  OK  ]
　　
# mysqladmin -u root password 'root'
　　
　　# mysql -uroot -proot
