Red hat Enterprise5再手工用rpm包装的mysql4.0，装完以后mysql不能通过service mysql start启动，只能通过/usr/share/mysql/mysql.server start启动，cp /usr/share/mysql/mysql.server /etc/init.d/mysql后可以用service mysql start，但是setup中添加自启动项无效，/etc/rc.local中加/usr/shar/mysql/mysql.server start或/usr/bin/mysqld_safe &均无效，手工可以启动mysql,程序就是自己启不来，很郁闷，怀疑是环境变量设置问题，哪位遇到过类似的问题........期待。

# /etc/my.cnf to set global options,

# installation this directory is /usr/local/hsltest/var) or

# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 2# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#

#master-user = root

# The password the slave will authenticate with when connecting to

现在发现as5中mysql的pid是/var/run/mysqld/mysqld.pid,而mysql4是/var/lib/myql/localhost.localdomain.pidpid文件是不是有区别？
