1.3 安装相关包
1.3.1 cmake软件
cd /home/oldboy/tools/
tar xf cmake-2.8.8.tar.gz
cd cmake-2.8.8
./configure
#CMake has bootstrapped. Now run gmake.
gmake
gmake install
cd ../
1.3.2 依赖包
yum install ncurses-devel –y
1.4.1 创建用户和组
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql
1.4.2 解压编译MySQL
tar zxf mysql-5.5.32.tar.gz
cd mysql-5.5.32
1.4.2 解压编译MySQL
tar zxf mysql-5.5.32.tar.gz
cd mysql-5.5.32

ln -s /application/mysql-5.5.32/ /application/mysql
在mysql-5.5.32解压包中 复制配置文件到etc下
Cp support-files/my-small.cnf /etc/my.cnf
配置环境变量
或者
vim /etc/profile
最底下修改:
PATH="/application/mysql/bin/:$PATH"
tail -1 /etc/profile
source /etc/profile
给data目录授权
chown -R mysql.mysql /application/mysql/data/
数据库初始化
cd /application/mysql/scripts/
./mysql_install_db --basedir=/application/mysql --datadir=/application/data --user=mysql
#没有错误的话进行下一步
进入mysql解压目录
cp support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld
basedir=/application/mysql
datadir=/application/mysql/data
cp support-files/my-small.cnf /etc/my.cnf
或者
cp -f support-files/my-small.cnf /etc/my.cnf
/etc/init.d/mysqld start
/etc/init.d/mysqld stop
如果启动报错 启动不了 就重新初始化
pkill mysqld
lsof -i :3306
rm -rf /application/mysql/data/*
修改数据库密码
/application/mysql/bin/mysqladmin -u root password '123456'
进入mysql库
/application/mysql/bin/mysql
或者添加到mysql命令
优化：
delete from mysql.user where host="::1";
delete from mysql.user where host="www";
delete from mysql.user where user="";
