CentOS下源码安装MySQL软件

步骤

1. 安装依赖包

   yum -y install gcc make cmake ncurses-devel libxm12-devel libtool-ltdl-devel gcc-c++ autoconf automake bison zlib-devel

2. 获取源码软件包

   yum -y install wget #安装wget
   wget http://cdn.mysql.com/archives/mysql-5.6/mysql-5.6.11.tar.gz #从官网拉去mysql软件源码包

3. 为数据库进程创建用户及组账户

   groupadd mysql # 添加用户组mysql
   useradd -r -s /sbin/nologin -g mysql mysql # 添加用户账户mysql

4. 将源码包解压到/usr/src/目录下

   tar -xzf mysql-5.6.11.tar.gz -C /usr/src/

5. 编译安装MySQL软件

   cd /usr/src/mysql-5.6.11/ #进入源码目录
   cmake . -DENABLE_DOWNLOADS=1 # 编译MySQL
   make && make install # 编译MySQL
   chown -R mysql.mysql /usr/local/mysql #改变文件夹归属

6. 初始化数据库

   使用mysql_install_db脚本初始化数据库，user定义数据库账户，basedir定义软件主目录，datadir定义数据库存放目录
   /usr/local/mysql/scripts/mysql_install_db –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data
   将mysql主配置文件mysql.cnf复制一份到/etc/目录下
   cp /usr/local/mysql/my.cnf /etc/my.cnf

7. 启动mysqld服务，并设置为开机启动

   使用mysqld_safe进程手动启动数据库服务进程
   /usr/local/mysql/bin/mysqld_safe –user=mysql &
   设置mysql开启启动
   cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
   chkconfig –add mysqld
   chkconfig mysqld on

8. 将mysql命令添加到环境变量中

   PATH= PATH:/usr/local/mysql/bin/echo“exportPATH= P A T H : / u s r / l o c a l / m y s q l / b i n / e c h o “ e x p o r t P A T H = PATH:/usr/local/mysql/bin/” >> /etc/profile

9. 更改数据库默认设置

   mysql -u root -e “select User,Host,Password from mysql.user”
   /usr/local/mysql/bin/mysql_secure_installation
