linux安装mysql5.6实时教程和配置


今天数据库服务器可以使用了，现在下一步就是安装mysql，决定mysql 版本为5.6.14

检查系统中是否已经安装过mysql。
rpm -qa | grep mysql
如下图：
\
如果存在，则需要删除。
yum -y remove mysql*
继续检查一下是否还存在mysql
rpm -qa " grep -i mysql
\
然后下一步就是下载rpm包了。需要下载：
MySQL-client-5.6.15-1.el6.x86_64.rpm
MySQL-devel-5.6.15-1.el6.x86_64.rpm
MySQL-server-5.6.15-1.el6.x86_64.rpm

逐一执行命令：
wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-client-5.6.15-1.el6.x86_64.rpm
wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-devel-5.6.15-1.el6.x86_64.rpm
wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-server-5.6.15-1.el6.x86_64.rpm

\
接下来就是安装了分别依次执行：
[root@iZ25in7iu0fZ rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm

修改配置文件位置。
[root@iZ25in7iu0fZ rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf初始化MySQL及设置密码
cp /usr/share/mysql/my-default.cnf /etc/my.cnf
/usr/bin/mysql_install_db
cat /root/.mysql_secret
记录最后的密码
mysql -p ---输入记录的密码，即可登录mysql。
set password for 'root'@'localhost' =password('新密码');
flush privileges;
exit设置自启动
chkconfig mysql on

MySQL的默认安装位置

1 /var/lib/mysql/ #数据库目录
2 /usr/share/mysql #配置文件目录
3 /usr/bin #相关命令目录
4 /etc/init.d/mysql #启动脚本
修改字符集和数据存放目录
原来配置文件：
\

更改之后为：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It"s a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.


[client]
port = 3306
default-character-set=utf8




[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 = /mnt/data/mysql
port = 3306
# server_id = .....
# socket = .....


lower_case_table_names=1


max_connections=1000


collation_server = utf8_general_ci
character_set_server = utf8


# default-character-set=utf8
# init_connect='SET NAMES utf8'




# 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


[mysql]
default-character-set = utf8

注意标红的。


然后就是修改数据库的数据目录：
vi /etc/init.d/mysql

\

重启数据库：


service mysql restart
大功告成。
