单实例MySQL安装

1、建立账号

[[email protected] ~]# groupadd mysql

[[email protected] ~]# useradd -s /sbin/nologin -g mysql -Mmysql

useradd参数说明：

-s/sbin/nologin 表示禁止该用户登录

-gmysql 指定属于mysql组

-M表示不创建用户家目录

2、配置安装环境

创建目录并授权：

[[email protected] ~]# mkdir /home/tools

[[email protected] ~]# mkdir -p /usr/local/mysql

[[email protected] ~]#mkdir -p /data/mysql

[[email protected] ~]#chown -R mysql.mysql /usr/local/mysql/

[[email protected] ~]#chown -R mysql:mysql /data/mysql

安装系统软件包：

[[email protected] ~]# yum install gcc gcc-c++ make cmakencurses-devel bison perl

配置解析：

[[email protected] ~]# hostname

opsedu

[[email protected] ~]# vim /etc/hosts

10.47.129.177 opsedu        添加一条

安装cmake：

[[email protected] ~]# rpm -qa | grep cmake   使用系统自带cmake，编译时，有时候会报错

cmake-2.8.12.2-4.el6.x86_64         版本2.8.12

[[email protected] ~]# yum remove cmake –y

[[email protected] ~]# cd /home/tools

[[email protected] tools]# wget https://cmake.org/files/v2.8/cmake-2.8.12.tar.gz

[[email protected] tools]# tar -zxf cmake-2.8.12.tar.gz

[[email protected] tools]# cd cmake-2.8.12

[[email protected] cmake-2.8.12]# ./configure

[[email protected] cmake-2.8.12]# gmake

[[email protected] cmake-2.8.12]# gmake install

[[email protected] cmake-2.8.12]# cd ..

[[email protected] tools]# cmake --version

cmake version 2.8.12

3、安装mysql

[[email protected] tools]# wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz

[[email protected] tools]# tar -zxf mysql-5.5.37.tar.gz

[[email protected] tools]# cd mysql-5.5.37

[[email protected] mysql-5.5.37]# cmake \

[[email protected] mysql-5.5.37]#/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql--datadir=/data/mysql --user=mysql

启动mysql:

[[email protected] mysql-5.5.37]#  /usr/local/mysql/bin/mysqld_safe --user=mysql&

[[email protected] mysql-5.5.37]# netstat -lnt|grep 3306
