采用源码安装，可以根据实际生产环境加入一些参数，提升mysql性能

mysql官网https://www.mysql.com/

本文采用5.1版本尽心安装说明，后面版本如5.5安装方法会有些不一样，在公司的一些生产环境中也有用到

5.1版本mysql。

下载mysql源码

解压tar zxf mysql-5.1.72.tar.gz

cd mysql-5.1.72

配置

./configure --prefix=/usr/local/mysql \

--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock \

--localstatedir=/usr/local/mysql/data\

--enable-assemble \

--enable-thread-safe-client \

--with-mysqld-user=mysql \

--with-big-tables \

--with-pthread \

--with-extra-charsets=complex \

--with-readline \

--with-ssl \

--with-mysqld-ldflags=-all-static \

--with-client-ldflags=-all-static

[root@backupserver mysql-5.1.72]# ./configure --help 查看具体的配置参数

make&&make install

这里采用开发测试模板

/bin/cp support-files/my-small.cnf/etc/my.cnf

创建数据库文件

mkdir -p /usr/local/mysql/data

chown -R mysql /usr/local/mysql授权mysql用户可以访问mysql目录

/usr/local/mysql/bin/mysql_install_db --user=mysql安装mysql数据库文件

安装完后会有一些相关说明，如如何启动等等。

安装安装说明方法启动mysql

/usr/local/mysql/bin/mysqld_safe/usr/local/mysql/bin/mysqld_safe &&表示后台运行

为了更方便的启动mysql，可以将mysql加到全局变量中

将mysql加到全局变量中echo 'export PATH=$PATH:/usr/local/mysql/bin'>>/etc/profile

source /etc/profile

执行mysql进入数据库

[root@backupserver mysql-5.1.72]# mysql

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 1

配置/etc/init.d/mysqld启动mysql

cp support-files/mysql.server /etc/init.d/mysqld

chmod 700 /etc/init.d/mysqld 授权，

将mysql服务加到开机启动

[root@backupserver mysql-5.1.72]# chkconfig --add mysqld

[root@backupserver mysql-5.1.72]# chkconfig mysqld on

mysql进入数据库

设置密码set password for root@localhost=PASSWORD('123456');

后续采用mysql -uroot -p形式进入mysql数据库
