这篇文章主要讲解了“Liunx下mysql源码安装步骤”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“Liunx下mysql源码安装步骤”吧！

环境：
虚拟机：CentOS-6.6-x86_64
mysql安装包：mysql-5.6.34

在安装源码包之前，需要安装一些rpm包
[root@potato ~]# rpm -qa|grep cmake
cmake-2.8.12.2-4.el6.x86_64
[root@potato ~]# rpm -qa|grep gcc
gcc-4.4.7-11.el6.x86_64
gcc-c++-4.4.7-11.el6.x86_64
[root@potato ~]# rpm -qa|grep make
make-3.81-20.el6.x86_64
[root@potato ~]# rpm -qa|grep make
[root@potato ~]# rpm -qa|grep libaio-devel
libaio-devel-0.3.107-10.el6.x86_64

创建用户mysql
[root@potato ~]# useradd mysql
从官网下载mysql数据库源码包，地址：
http://dev.mysql.com/downloads/mysql/
将下载的tar包进行解压
[root@potato ~]# cd Desktop/
[root@potato Desktop]#tar -zxvf /tmp/soft
创建软件存放目录
[root@potato Desktop]#mkdir /opt/mysql/mysql-5.6
[root@potato Desktop]#cd /tmp/soft
[root@potato soft]# cd mysql-5.6.34/
[root@potato mysql-5.6.34]#mkdir temp
开始编译，并指定软件存放目录
[root@potato temp]#cmake -DBUILD_CONFIG=mysql_release  -DCMAKE_INSTALL_PREFIX=/opt/mysql/mysql-5.6 ..
[root@potato temp]#make –j 
[root@potato temp]#make install
自此mysql软件安装完成

在/usr/local目录下配置mysql软连接，并设置PATH变量
[root@potato unbx]#  cd /usr/local/
[root@potato local]# ln -s /opt/mysql/mysql-5.6 mysql
[root@potato local]# echo "PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
[root@potato local]# source /etc/profile
[root@potato mysql]# echo $PATH
/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/root/bin:/usr/local/mysql/bin

创建data目录并赋权
[root@potato local]# mkdir -p /data/mysql/mytest_3306
[root@potato local]# chown -R mysql:mysql /data/mysql/mytest_3306
[root@potato local]# cd /usr/local/mysql
[root@potato mysql]# chown -R mysql:mysql *
创建配置文件my.cnf
[root@potato mysql]# cd /etc
[root@potato mysql]# vi /etc/my.cnf
注：可以在https://tools.percona.com，按步骤自动生成my.cnf
初始化数据库，指定my.cnf文件
[root@potato mysql]# ./scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

把mysql.server复制到/etc/init.d目录下，并开启mysql服务
[root@potato mysql]# cp support-files/mysql.server /etc/init.d/mysql
[root@potato mysql]# /etc/init.d/mysql start
Starting MySQL... SUCCESS! 
连接mysql
[root@potato mysql]# mysql
