A very cool thing: Install MYSQL from source without root access on LINUX
最近由于工作的需要，要在centos上安装MYSQL服务器。作为一名小兵中的小兵，当然是没有root权限的，为了能够使用mysql，只能使用源码安装了（因为binary安装方式似乎需要root access的）
一、Mysql下载
mysql.5.6.24
二、解压
tar zxvf mysql.tar.gz
三、配置
参考了许多地方，最后稀里糊涂进行了一下配置，关键是安装的位置，数据库的位置，配置文件的位置这三个吧
cmake ./ -DCMAKE_INSTALL_PREFIX=$HOME/local/mysql \
-DMYSQL_DATADIR=$HOMElocal/mysql/data \
-DSYSCONFDIR=$HOME/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=$HOME/local/tmp/mysqld.sock \
-DMYSQL_TCP_PORT=8812 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci
四、安装
make && make install
五、安装数据库
这里实际上刚开始一致不太成功，原因是mysql一直去找一个写默认的位置，当然是没有写的权限的，最后在[1]得到了非常大的启发。
实际上，为了屏蔽掉这些默认的设置我们只需要找一个配置文件作为这些命令的输入就可以了
./scripts/mysql_install_db --defaults-file=~/my.cnf --user=martin --basedir=$HOME --datadir=/home/martin/sql_data --socket=/home/martin/socket
上面的参数value要具体改为我们自己的value
上面的那个my.cnf文件非常关键，我们最好考一个安装成功之后再一定的目录下面
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

六、启动
./mysqld_safe --defaults-file=/home/guofeng/local/etc/mysql/my.cnf --skip-grant-tables&
ps -ef | grep mysql
七、进入数据库
mysql -u root -p
随便输入一个密码
进去之后创建一个新的用户[2]
创建用户，授权.
Sql代码
create user lzquan identified by '123456';
grant all privileges on *.* to 'lzquan'@'localhost' identified by '123456';
flush privileges;
Sql代码
删除用户,收回权限
Sql代码
delete from mysql.user where user='lzquan' and host='localhost';
revoke all on testuser .* from 'lzquan'@localhost;
八、如何通过ip地址访问数据库？
在实际当中访问数据库，当然要通过ip地址，但是mysql这是如果使用ip地址进行访问就会出现问题。
在[3]中找到了答案。
