无root权限安装mysql过程分享
因为没有权限，编译高版本容易进入安装依赖软件的死胡同，属于选择V5.5、V5.6相对较容易编译。
1、安装编译工具
此处仅讲cmake，其他的软件在configure过程会提示。到http://www.cmake.org/files/选择最新版的cmake链接，然后下载安装：
wget http://www.cmake.org/files cd cmake ./configure --prefix=/home/cmake make && make install
然后将cmake目录加入环境变量(或者在~/local/bin下面建立链接cmake可执行程序的软链接, ~/local/bin是我自己的bin目录, 已经加入到环境变量$PATH中)：编辑~/.bashrc或者~/.bash_profile，加入以下内容：
export PATH=/home/cmake:$PATH
让其生效
. ~/.bashrc
2、编译、安装MySQL
（1）到mysql历史版本下载地址https://downloads.mysql.com/archives/community/下载合适的版本。
tar -zxvf mysql.tar.gz cd mysql cmake -DCMAKE_INSTALL_PREFIX=/home/mysql -DMYSQL_TCP_PORT=39393 make && make install
检查端口是否别占用：netstat -apn | grep 39393
（2）将MySQL的bin目录和scripts目录加入环境变量：编辑~/.bashrc或者~/.bash_profile，加入以下内容：
export PATH=~/local/app/mysql/bin:~/local/app/mysql/scripts:$PATH
让其生效
. ~/.bashrc
（3） 配置mysql配置文件my.cnf(本博客的重点）
# Example MySQL config file for very large systems.
# This is for a large system with memory of 1G-2G where the system runs mainly
# MySQL.
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 39393
socket = /home/mysql/mysql.sock
[mysqld]
port = 39393
socket = /home/mysql/mysql.sock
basedir = /home/mysql
datadir = /home/mysql/data
tmpdir= /home/mysql/tmp
innodb_data_home_dir = /home/mysql/data
innodb_data_file_path = ibdata1:1000M:autoextend
#loose-skip-innodb
default-storage-engine = MyISAM
innodb_use_sys_malloc = 0（4）执行安装命令：./script/mysql_install_db --defaults-file=my.cnf --user=user
（5）启动mysql
bin/mysqld_safe --defaults-file=my.cnf
（6）进入mysql
bin/mysql --socket=mysql.sock -uroot -p

解决方案：在my.cnf中加入
#loose-skip-innodb
default-storage-engine = MyISAM本文纪念摸索3天让自己濒临崩溃的安装经历。
