Linux下MySQL二进制部署

1.下载mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz，linux下已经安装了vmware-tools，就可以直接把下载下来的包拖到linux桌面，如果没有下载的话，安装sercureCRT ，终端下输入rz，选择本地文件下载到linux桌面

2.判断一下电脑之前是否安装MySQL

下图所示之前未安装MySQL

已安装过mysql

3.解压文件和对文件进行重命名

tar -xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

 mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

4.创建用户组和用户

groupadd -g 101 dba

创建一个dba组，组号是101 ，又创建一个514的用户，主组是dba组，-d重定向到家目录，专门创建一个mysqladmin用户

为什么要创建mysqladmin/dba？
1.一个用户只对一个组件
2.dba组

5.复制环境变量配置文件至mysqladmin用户的home目录中

6.在/etc目录下创建my.cnf配置文件

vi  my.cnf进行编辑，gg跳转到第一行，dG清空文件，复制以下文字到my.cnf，注意保存退出

注意：innodb_buffer_pool_size = 2048M  最好改为 innodb_buffer_pool_size = 512M（虚拟机内存限制）

7.修改用户和用户组的名字以及权限

8.创建arch目录进行第一次安装

mkdir arch

scripts/mysql_install_db          scripts脚本文件中的mysql_install_db进行安装

--user=mysqladmin 

--basedir=/usr/local/mysql 

--datadir=/usr/local/mysql/data

注意：1.可能出现的问题缺少libaio包 ，yum -y install libaio

2.在/etc/my.cnf下修改内存时多了空格号

如果要重新部署mysql ,把这个目录删除:rm -rf arch/*  data/*  再重新进行安装

9.配置mysql文件和开机自启动

#将服务文件拷贝到init.d下，并重命名为mysql
[[email protected] mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 
#赋予可执行权限
[[email protected] mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[[email protected] mysql]# chkconfig --del mysql
#添加服务
[[email protected] mysql]# chkconfig --add mysql

[[email protected] mysql]# chkconfig --level 345 mysql on

10.启动mysql并查看进程以及监听端口

su - mysqladmin
rm -rf my.cnf        配置的my.cnf文件位于etc/my.cnf

 bin/mysqld_safe &   启动数据库

ps -ef|grep mysqld  检查mysql进程是否存在

netstat tulnp|grep mysql   查看端口情况

11.登入mysql

1.终端下输入mysql 回车进入

2.mysql -uroot -p 直接回车2次 root 空密码
