Mysql快速配置安装方法(备)
Mysql5.5安装配置在Centos上，由于以后有项目要进行几个架构的探讨，所以先自己在虚拟机上测试一套主从，读写分离的集群来测试环境！
虚拟机采用的是，vmware workstation8.0，linux：centos5.5版本的！
虚拟机装系统很简短就不再截图出来，网络采用桥接方式，并且要求能联网ping通。为了以后更新RPM包使用yum命令，减少依赖包的障碍！
一、安装cmake
# 安装所需依赖包
yum -y install gcc libxml2-dev curl screen \
libpng12-dev autoconf libpcre3-dev make bzip2 \
libevent-dev patch libjpeg62-dev libcurl4-openssl-dev \
libfreetype6-dev g++ libtool libncurses5-dev psmisc lrzsz
同时也要更更新以下的包；
Yum –y install gcc* gcc-c++* autoconf* automake* zlib* libxml* ncurses-devel*libgcrypt* libtool*
# 下载文件
wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz
# 编译安装
tar zxvf cmake-2.8.5.tar.gz
cd cmake-2.8.5
./boostarp
make
make install
cmake –version
这里我把所有的包都存放到/usr/local/这个目录下，包括下面下载的mysql安装包；
[root@slave01 local]# ls
bin cmake-2.8.5.tar.gz etc games include lib libexec sbin share src
[root@slave01 cmake-2.8.5]# cmake -version
cmake version 2.8.5
二、 安装配置mysql
# 下载源文件
wgethttp://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.17.tar.gz/from/ftp://ftp.ntu.edu.tw/pub/MySQL/
# 或
wget ftp://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.5/mysql-5.5.17.tar.gz
以上连个链接有问题，大家随便到网上搜搜，就有很多mysql5.5的安装包，这个不难。
# 创建用户和组
groupadd mysql
useradd -g mysql -s /usr/sbin/nologin mysql
# 创建安装目录
mkdir /usr/local/ mysql
# 创建数据库目录
mkdir /usr/local/ mysql/data
# 解压
tar -zxvf mysql-5.5.17.tar.gz
cd mysql-5.5.17
# 编译及安装mysql
# cmake编译：
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_unicode_ci \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_DEBUG=0
运行以后出现以下错误；

Warning: Bisonexecutable not found in PATH
-- Configuring incomplete, errors occurred!
You have mail in /var/spool/mail/root
安装下bison包，
Yum –y install bison*
再次运行出现新错误，不要着急，遇到错误，应该是很欣慰，现在知道了，以后就有把握自己处理，不必再百度，谷歌，满世界询问了

此错误提示很清楚，有个包缺少，yum下即可。遇错误一定仔细看错误信息，这是你成为牛人的关键一步；
[root@slave01 mysql-5.5.13]# cmake-DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data-DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_unicode_ci -DWITH_READLINE=1-DWITH_SSL=system -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1-DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1-DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_DEBUG=0

我装好包以后再次运行，依然有err出现，这里是因为，我们在多次运行的时候cmake有个文件我们需要删除，需要在安装新包的情况下，重新应用下相关的文件；
删除当前目录CMakeCache.txt并重新运行：
Cmake .
看清楚有个点，并且有个空格；
再次运行cmake命令就会正常；
# 安装mysql
make && make install
# 复制配置文件
cp support-files/my-medium.cnf /etc/my.cnf
# 设置权限
chmod +x /usr/local/mysql
chown -R mysql.mysql /usr/local/mysql
chown -Rmysql:mysql /usr/local/mysql/data
# 配置开机自启动
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig –add mysqld
chkconfig mysqldon
# 修改my.cnf配置
vim /etc/my.cnf
# [mysqld] 添加：
datadir=/usr/local/mysql/data
default-storage-engine=MyISAM
# 以下可选：
log-error =/usr/local/mysql/data/error.log
pid-file = /usr/local/mysql/data/mysql.pid
user = mysql
tmpdir = /tmp
# 初始化数据库
/usr/local/mysql/scripts/mysql_install_db --user=mysql--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &
# 启动MySQL
/usr/local/mysql/bin/mysqld_safe –defaults-file=/etc/my.cnf &
或者：
/etc/init.d/mysql start （service mysql start）
# 测试MySQL是否启动
# 1）查看是否有进程mysql
ps -ef | grep mysql
# 2）查看端口是否运行
netstat -tnl | grep 3306
# 3）读取mysql版本信息
/usr/local/mysql/bin/mysqladmin version
# 至此，MySQL安装完成
安装的mysql的root密码一般都是空，我们可以设置它为我们指定的密码；
首先登陆mysql，然后执行下面命令即可；
SET PASSWORD FOR 'root'@'localhost' =PASSWORD('your new password');
flush privileges;
