一、准备工作

创建Download

bash 复制代码 
[root@centos001 ~]# 
[root@centos001 ~]# cd /opt/
[root@centos001 opt]# mkdir download
mkdir: 无法创建目录"download": 文件已存在
[root@centos001 opt]# ls
download

更换源

bash 复制代码 
[root@centos001 download]# vi /etc/yum.repos.d/CentOS-Base.repo
bash 复制代码 
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

一、安装MySQL

1.1 预安装的依赖

bash 复制代码 
安装GCC：yum install gcc -y
安装PERL：yum install perl -y
安装AUTOCONF：yum  install autoconf -y
安装LIBAIO：yum install  libaio -y

1.2 安装MySQL

1、配置ip映射

修改主机名：/etc/hostname

修改ip映射：/etc/hosts

bash 复制代码 
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.101 c001
bash 复制代码 
[root@centos001 ~]# ping c001

[root@centos001 mysql]#

4、配置环境变量

bash 复制代码 
[root@centos001 mysql]# vi /etc/profile
#mysql环境变量
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

记得刷新~！！！！！！！！

bash 复制代码 
[root@c001 mysql]# source /etc/profile
[root@c001 mysql]# clear
[root@c001 mysql]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket 
'/tmp/mysql.sock' (2)

5、创建mysql专属用户和用户组

切记不要设置密码~！！！！！！！

bash 复制代码 
[root@centos001 mysql]# groupadd mysql
[root@centos001 mysql]# useradd -g mysql mysql
[root@centos001 mysql]#

6、创建数据目录

1.3 远程访问

1、关闭防火墙

bash 复制代码 
#centos7之前
关闭命令：service iptables stop
永久关闭防火墙：chkconfig iptables off
查看防火墙关闭状态 ：service iptables status
#centos7之后
临时关闭：systemctl stop firewalld
永久关闭：systemctl disable firewalld
查看防火墙状态：systemctl status firewalld
[root@c001 /]# systemctl stop firewalld
[root@c001 /]# systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
[root@c001 /]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
