编译安装Mysql5.5数据库软件
准备环境：Centos6.5（6系列操作系统）# yum -y install gcc gcc-c++ ncurses-devel libxml2-devel zlib-devel pcre-devel
# tar zxvf bison-2.5.tar.gz
# cd bison-2.5
# ./configure &&make &&make install
# tar zxvf cmake-2.8.7.tar.gz
# cd cmake-2.8.7
# ./bootstrap &&gmake &&gmake install
# tar zxvf mysql-5.5.22.tar.gz
# cd mysql-5.5.22
# useradd mysql
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DSYSCONFDIR=/etc/ &&make &&make install
参数注释：安装目录、默认编码、校验字符集、安装所有扩展字符集、配置文件目录
# chown -R :mysql /usr/local/mysql
# cd /usr/local/mysql/support-files
# cp my-medium.cnf /etc/my.cnf
# cp mysql.server /etc/init.d/mysqld
# cd ../scripts/
下面操作将进行mysql初始化，指定基础目录，存放数据目录，及运行用户
# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
# /etc/init.d/mysqld start
# echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
# source /etc/profile
# mysqladmin -u root password 'redhat'设置mysql运行账户及密码，这个root可不是系统用户的root哦！
# mysql -u root -p
Enter password:
OK，安装完成
