安装mysql

#查看是否已经安装mysql 如果有则删除

rpm -qa|grep -i mysql

rpm -ev mysql-libs-*

rpm -ev mysql-server-5.1.73-3.el6_5.i686

rpm -ev mysql-devel-5.1.73-3.el6_5.i686

1，二进制安装

#解压

tar -zxvf mysql-5.5.33-linux2.6-i686.tar.gz

mv mysql-5.5.33-linux2.6-i686 /application/mysql

cd /application/mysql/

#创建用户和用户组

groupadd mysql

useradd mysql -g mysql -M -s /sbin/nologin

　　

2，cmake安装

groupadd mysql

useradd mysql -g mysql -M -s /sbin/nologin

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。

添加mysql到环境变量

vim /etc/profile  

在最后面添加

PATH="/application/mysql/bin/:$PATH"

 source  /etc/profile 

或者

echo 'export PATH=/application/mysql/bin/:$PATH' >> /etc/profile
tail -l /etc/profile
source /etc/profile
echo $PATH

给data目录授权

chown  -R mysql.mysql  /application/mysql/data

chmod -R 1777 /tmp/

　　

初始化mysql

 ./scripts/mysql_install_db  --user=mysql --basedir=/application/mysql/ --datadir=/application/mysql/data/

 #没有错误的话进行下一步

一般会出现两个ok表示成功

Installing MySQL system tables...
OK
Filling help tables...
OK

　　

进入mysql解压目录 启动文件

 cp support-files/mysql.server  /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld 

 vim /etc/init.d/mysqld

basedir=/application/mysql

datadir=/application/mysql/data

　　

配置文件：回到安装目录/application/ mysql-5.5.32

cp mysql-5.5.32/support-files/my-small.cnf /etc/my.cnf

启动：

/etc/init.d/mysqld start

/etc/init.d/mysqld stop

 

设置密码：

/application/mysql/bin/mysqladmin  -u root password '123456'
