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；

-- Check size of wchar_t - done

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

[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

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

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;
