简介
采用yum安装lamp简单，快捷，在工作中也得到了普遍应用。但是如果我们需要某些特定模块功能，以及制定安装位置等，就需要用到编译安装了，接下来将编译安装lamp之mysql. mysql的简介网上已经有很多材料，这里就不再赘述，注重演示如何安装mysql.
系统环境及服务版本

移动解压包至/usr/local/目录之下
[root@ken ~]# mv mysql-5.5.-linux2.-x86_64 /usr/local
[root@ken ~]# cd /usr/local
[root@ken local]# ls
bin include libexec share
etc lib mysql-5.5.-linux2.-x86_64 src
games lib64 sbin
[root@ken local]# ln -s mysql-5.5.-linux2.-x86_64 mysql #对这个包做一个软连接名为mysql
创建用户mysql
[root@ken local]# groupadd -r mysql
[root@ken local]# useradd -g mysql -r -s /sbin/nologin mysql
[root@ken local]# cd mysql
[root@ken mysql]# chown -R mysql.mysql ./* #以mysql用户来运行mysql
创建数据库数据目录
[root@ken mysql]# mkdir /ken
[root@ken mysql]# chown -R mysql.mysql /ken

read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
thread_cache_size =
query_cache_size = 32M
# Try number of CPU's*2 for thread_concurrency
thread_concurrency =
datadir=/ken #40行左右添加刚才创建的数据保存路径 # Don't listen on a TCP/IP port at all. This can be a security enhancement,
...
生成mysql的服务管理脚本
[root@ken support-files]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@ken support-files]# chkconfig --add mysqld
[root@ken support-files]# chkconfig mysqld on
启动mysql
[root@ken support-files]# systemctl start mysqld
[root@ken support-files]# ss -tnl
