从mysql.com下载了一个最新的mysql.5.6.17后安装后,因原机器安装过mysql,启动总是报错
检查了一下mysql的原安装目录里面有个一新的myql-new.conf。
对比了下原/etc/my.conf和mysql-net.conf在mysql.5.6.17这个版本下有很大不同
原my.conf配置内容
[root@nginx01 bin]# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
mysql_enable="YES"
mysql_args="--skip-grant-tables --skip-networking"
新配置的my.conf
[root@nginx01 mysql]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
其中这个网址http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html是mysql.5.6.17最新的配置
将安装目录下面的这个文件覆盖后
重启mysql
[root@nginx01 bin]# ./mysqld_safe --user=mysql &
[1] 30069
[root@nginx01 bin]# 140518 11:21:42 mysqld_safe Logging to '/usr/local/mysql/data/nginx01.err'.
