第1章 概述

Dataviz在部署的时候需要一个数据库来运行支撑库，有时候就需要在客户的Linux环境上安装MySQL。

第2章 安装步骤

  1. 获取mysql-5.5.57-linux-glibc2.12-x86_64.tar.gz，并把mysql-5.5.57-linux-glibc2.12-x86_64.tar.gz上传到 /usr/local
  2. 检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称） rpm -qa | grep -i mysql
    mysql-libs-5.1.66-2.el6_3.x86_64
    yum -y remove mysql-libs*
  3. 进入usr/local/目录 cd /usr/local/
  4. 解压 tar -zxvf mysql-5.5.57-linux-glibc2.12-x86_64.tar.gz
  5. 重命名文件夹名称 mv mysql-5.5.57-linux-glibc2.12-x86_64 mysql
  6. 添加系统mysql组和mysql用户 groupadd mysql useradd -r -g mysql mysql
  7. 进入mysql目录 cd mysql
  8. 修改当前目录拥有者为mysql用户 chown -R mysql:mysql ./
  9. 进入support-files目录，查看是否有my_default.cnf文件 cd support-files / ll ./MySQL_on_linux/1
  10. 如果没有，则需要创建一个my_default.cnf文件上传到/usr/local/mysql/support-files目录下。文件内容如下：
# 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.

  1. 安装数据库 cd .. ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql
  2. 复制配置文件，提示是否覆盖 输入“Y” cp support-files/my-default.cnf /etc/my.cnf
  3. 添加开机启动，提示是否覆盖 输入“Y” cp support-files/mysql.server /etc/init.d/mysql
  4. 修改启动脚本 vi /etc/init.d/mysql
  5. 修改项： basedir=/usr/local/mysql/ datadir=/usr/local/mysql/data/mysql
  6. 创建socket目录，并授权 mkdir -p /var/run/mysqld chown mysql:mysql /var/run/mysqld
  7. 启动服务 service mysql start
  8. 查看是否启动成功 ps -ef|grep mysql ./MySQL_on_linux/2

  9. 加入环境变量，这样可以在任何地方用mysql的命令了 export PATH=$PATH:/usr/local/mysql/bin source /etc/profile

  10. 修改root账户密码 mysqladmin -u root password '密码'

  11. 连接mysql mysql –uroot –p
  12. 输入密码后连进入控制台

./MySQL_on_linux/3

  1. 修改可远程访问 set sql_safe_updates=0; use mysql update user set host = '%' where user = 'root'; flush privileges; exit
  2. 如果有防火墙还需要修改防火墙的配置，开通3066端口 vi /etc/sysconfig/iptables
  3. 添加一行 -A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT
  4. 重启防火墙 service iptables restart
