linux 下安装 myslq

环境：Centos7.2_64

　　

　　1. 安装编译工具及库文件

[root@centos7 src]# yum -y install gcc gcc-c++ make autoconf libtool-ltdl-devel gd-devel freetype-devel libxml2-devel libjpeg-devel libpng-devel openssl-devel curl-devel bison patch unzip libmcrypt-devel libmhash-devel ncurses-devel sudo bzip2 flex libaio-devel

 

　　2. 安装 cmake 编译器   版本：cmake-3.1.1。

安装 cmake 编译器 版本：cmake-3.1.1。
[root@centos7 src]# wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

解压安装包
[root@centos7 src]# tar zxvf cmake-3.1.1.tar.gz

进入安装包目录
[root@centos7 src]# cd cmake-3.1.1

编译安装 （安装过程有点慢，需要耐心等）
[root@centos7 src]# ./bootstrap
[root@centos7 src]# make && make install

 

 　　3. 查看 mysql 版本

[root@centos7 mysql-5.6.15]# /usr/local/webserver/mysql/bin/mysql --version

 

 　　4. 创建 mysql 运行用户

[root@centos7 mysql-5.6.15]# /usr/sbin/groupadd mysql
[root@centos7 mysql-5.6.15]# /usr/sbin/useradd -g mysql mysql

　　

　　5. 创建binlog和库的存储路径并赋予mysql用户权限

[root@centos7 mysql-5.6.15]# mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql
[root@centos7 mysql-5.6.15]# chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/

　　

　　6. 修改 mysql 配置文件 my.cnf  （地址：/etc/my.cnf）（建议先备份）

 　　7. 初始化 MySQL 数据库

[root@centos7 mysql-5.6.15]# cd /usr/local/webserver/mysql
[root@centos7 mysql]# /usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

　　

　　8. 创建开机启动脚本

[root@centos7 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld 
[root@centos7 mysql]# chkconfig --add mysqld 
[root@centos7 mysql]# chkconfig --level 35 mysqld on

 

 　　9. 启动mysql服务器

[root@centos7 mysql]# chown mysql. mysql /usr/local/webserver/mysql
[root@centos7 mysql]# service mysqld start

　　　　　　先修改一下权限：

　　　　　　启动 mysql 服务

 　　　　　连接 MySQL　　　

[root@centos7 mysql]# /usr/local/webserver/mysql/bin/mysql -u root -p

　　　　　　如有报错使用如下命令操作mysql： 

systemctl restart mysqld.service 
systemctl start mysqld.service 
systemctl stop mysqld.service

 

 　　10. 修改MySQL当前用户密码

mysql> SET PASSWORD = PASSWORD('newpassword');

　　　　创建新用户并授权　　

grant all privileges on *.* to 用户名@'%' identified by '密码' with grant option;

　　

　　11. 其他命令

启动：service mysqld start
停止：service mysqld stop
重启：service mysqld restart
重载配置：service mysqld reload
