Linux安装mysql教程

1,设置安装路径

安装文件下载目录:/data/software
Mysql目录安装位置:/usr/local/mysql
数据库保存位置:/data/mysql
日志保存位置:/data/log/mysql

2,下载Mysql

在官网:http://dev.mysql.com/downloads/mysql/ 中,选择以下版本的mysql下载:

执行如下命名:
#mkdir /data/software
#cd /data/software

--下载安装包 

--建议:在windows上下载,然后用工具(Xftp)上传到 /data/software目录下;
#wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

3,解压压缩包到目标位置

#cd /data/software

--解压压缩包

#tar -xzvf /data/software/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

--移动并修改文件名

#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql

4,创建数据仓库目录

--/data/mysql 数据仓库目录
# mkdir /data/mysql         
#ls /data/

5,新建mysql用户、组及目录

#      ---新建一个msyql组
# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql     ---新建msyql用户禁止登录shell

6,改变目录属有者

#cd /usr/local/mysql
#pwd
#chown -R mysql .
#chgrp -R mysql .

 #chown -R mysql /data/mysql

7,配置参数

# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

此处需要注意记录生成的临时密码,如上文结尾处的:YLi>7ecpe;YP
#bin/mysql_ssl_rsa_setup  --datadir=/data/mysql

8,修改系统配置文件

#cd /usr/local/mysql/support-files

技术图片

# cp my-default.cnf /etc/my.cnf
# cp mysql.server /etc/init.d/mysql

# vim /etc/init.d/mysql

修改以下内容:

 9,启动mysql

# /etc/init.d/mysql start

--登陆

# mysql -hlocalhost -uroot -p

  --如果出现:-bash: mysql: command not found

  --就执行: # ln -s /usr/local/mysql/bin/mysql /usr/bin --没有出现就不用执行

--输入第6步生成的临时密码

--修改密码

mysql> set password=password(‘root‘);

--设置root账户的host地址(修改了才可以远程连接)

mysql>grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘;
mysql>flush privileges;

--查看表

mysql> use mysql;
mysql> select host,user from user;

--这里就可以使用远程连接测试了;

如提示不能成功连接,可能需要添加需要监听的端口

/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

 10,添加系统路径

# vim /etc/profile
添加:
export PATH=/usr/local/mysql/bin:$PATH
如下:

 技术图片

# source /etc/profile

11,配置mysql自动启动

# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on

注意:

--退出mysql命令窗口

#exit

 --查看mysql状态

#service mysql status

--停止mysql

#service mysql stop

--启动mysql

#service mysql start

12,附my.cnf

/etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/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.

[mysqld]

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 10G

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.

basedir = /usr/local/mysql
datadir = /export/mysql/var
port = 3306
server_id = 22206

binlog_format = statement

join_buffer_size = 128M

read_rnd_buffer_size = 2M
log_bin_trust_function_creators = on
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

lower_case_table_names=1
