1、Mysql数据库企业生产常用的几种安装方法。
（1）yum方式安装
yum方式安装适合对数据库要求不太高的场合，例如并发不大，公司内部，企业内部的一些应用场景
,大的门户把源码根据企业的需求制作成rpm,搭建yum仓库，yum install xxx-y。
（2）采用cmake方式编译安装
由于MySQL5.5.xx-5.6.xx产品系列特殊性，采用cmake方式编译安装。即./cmake;make;make install。生产场景的具体命令及参数为：

tar zxt mysql-5.5.32.tar.gz
cd mysql-5.5.32
.......

（3）采用二进制方式安装

2、mysql安装

1)
 1008  mkdir /home/oldboy/tools 
 1009  cd /home/oldboy/tools
 1010  rz -y #上传cmake安装包
 1011  tar -xf cmake-2.8.8.tar.gz 
 1012  cd cmake-2.8.8
 1013  ./configure #编译
 1014  gmake
 1015  gmake install
 1016  cd ../

2)依赖包
 yum install ncurses-devel -y 

3)创建用户和组
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql
 

4)开始安装
tar zxf mysql-5.5.32.tar.gz 
cd mysql-5.5.32
cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \
-DMYSQL_DATADIR=/application/mysql-5.5.32/data \
-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
-DWITH_FAST_MUTEXES=1 \
-DWITH_ZLIB=bundled \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH_DEBUG=0

make && make install

#成功后，软链接
ln -s /application/mysql-5.5.32/ /application/mysql

*选择配置文件
cp mysql-5.5.32/support-files/my-small.cnf /etc/my.cnf
测试环境选小的，生产环境可以根据硬件选择，如my innodeb heavy 4G.conf

*配置环境变量
echo 'export PATH=/application/mysql/bin:$PATH'>>/etc/profile
tail -1 /etc/profile
source /etc/profile
echo $PATH

*初始化数据文件(容易出错的步骤)
chown -R mysql.mysql /application/mysql/data/
chmod -R 1777 /tmp/
cd /application/mysql/scripts/
./mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql

*启动
cd /home/oldboy/tools/mysql-5.5.32
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
/etc/init.d/mysqld start

摘录：
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 开始安装mysql
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
cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32
-DMYSQL_DATADIR=/application/mysql-5.5.32/data
-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii
-DENABLED_LOCAL_INFILE=ON
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_FEDERATED_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1
-DWITHOUT_PARTITION_STORAGE_ENGINE=1
-DWITH_FAST_MUTEXES=1
-DWITH_ZLIB=bundled
-DENABLED_LOCAL_INFILE=1
-DWITH_READLINE=1
-DWITH_EMBEDDED_SERVER=1
-DWITH_DEBUG=0

#-- Build files have been written to: /home/oldboy/tools/mysql-5.5.32
提示，编译时可配置的选项很多，具体可参考结尾附录或官方文档：
make
#[100%] Built target my_safe_process
make install
ln -s /application/mysql-5.5.32/ /application/mysql
如果上述操作未出现错误，则MySQL5.5.32软件cmake方式的安装就算成功了。
