【MySQL学习笔记】CentOS 6.6上二进制方式安装MySQL 5.6

二进制安装时基于已安装好的MysqL，

可以参考这个：【MySQL学习笔记】CentOS 6.6上源码编译方式安装MySQL 5.6

把已安装好的MysqL，也就是把/usr/local/MysqL 目录直接打包压缩，把压缩文件放到要安装MysqL的机器上，解压之后，MysqL就安装好了。

不过，安装好之后，好需要进行各种配置。

安装、配置过程如下：

一、把MysqL程序打包压缩

[root@wc1 MysqL]# cd /usr/local/MysqL
[root@wc1 MysqL]# tar -zcvf /root/Desktop/MysqL-5.6.12.bin.tar.gz

二、把压缩包复制到要安装MysqL的机器上解压，然后移动到目标目录

[root@wc1 MysqL]# cd /root/Desktop
[root@wc1 Desktop]# tar -zxvf /root/Desktop/MysqL-5.6.12.bin.tar.gz 
[root@wc1 Desktop]# mv usr/local/MysqL  /usr/local

三：在shell脚本中执行su命令、转换文件格式
由于脚本文件在运行的过程中要切换到MysqL 用户，也就是命令：su - MysqL，导致接下去的命令行都不执行，只有在输入 exit 命令后，才会继续运行，但是运行之后也是有问题的。
然后，搜索解决的办法，从这篇文章中受到启发：http://blog.csdn.net/huashnag/article/details/43967237，感谢作者。

另外，由于shell脚本是在windows下编辑的，linux环境中无法运行，报错：

command not found 3：
command not found 4
command not found 5

QQ群中一个热心的网友说，这是格式问题，需要安装dos2unix，把windows下编辑的文件，转成unix格式的，类似这样：

dos2unix 文件名

然后，在网上搜索安装方法，安装dos2unix：

[root@wc1 Desktop]# yum -y dos2unix unix2dos
Loaded plugins: fastestmirror,refresh-packagekit,security
No such command: dos2unix. Please use /usr/bin/yum --help
[root@wc1 Desktop]# yum -y install dos2unix unix2dos

Complete!
[root@wc1 Desktop]#

四、脚本

主要有2个脚本文件。

1、MysqL_run.sh：在root账号下运行，主要是做一些预备的工作，最后会调用 MysqL.sh脚本。

2、MysqL.sh：在MysqL账号下运行。

五、MysqL_run.sh

#1.创建用户组、用户、修改目录属主
groupadd MysqL

useradd -g MysqL MysqL

chown -R MysqL:MysqL /usr/local/MysqL


#2.修改用户的bash配置文件，在用户登录后，设置语言、执行路径 环境变量
echo "export LANG=zh_CN.UTF-8" >> /home/MysqL/.bash_profile
echo "export PATH=/usr/local/MysqL/bin:\$PATH" >> /home/MysqL/.bash_profile


#3.创建MysqL要用的数据目录
mkdir -p /data/MysqLdata/{3306/{data,tmp,binlog},backup,scripts} 

chown -R MysqL:MysqL /data/MysqLdata 


#4.设置开机自启动项，里面引用到的脚本是在MysqL.sh脚本中创建的
#  通过sed编辑/etc/sudoers文件:
#         1.通过增加 MysqL   ALL=(ALL)   ALL,使得MysqL账号能使用sudo命令,#         2.注释 Defaults    requiretty，在终端tty也能执行sudo命令
#
echo "">>  /etc/rc.local 
echo "#autostart MysqL">> vi /etc/rc.local
echo "sudo -i -u MysqL /data/MysqLdata/scripts/MysqL_db_startup.sh 3306 > /home/MysqL/MysqL_db_startup.log 2>&1" >> /etc/rc.local 

sed -i -e '/^root\s*ALL=(ALL)\s*ALL$/a\MysqL    ALL=(ALL)    ALL' -e's/^Defaults    requiretty/#Defaults    requiretty/'  /etc/sudoers


#5.在/etc/security/limits.conf文件中增加nproc最大能打开的进程数、nofile最大能打开的文件数 限制
echo "MysqL    soft    nproc           2047" >>/etc/security/limits.conf
echo "MysqL    hard    nproc           16384" >>/etc/security/limits.conf
echo "MysqL    soft    nofile           1024" >>/etc/security/limits.conf
echo "MysqL    hard    nofile           65536" >>/etc/security/limits.conf


#6.把MysqL.sh文件拷贝到MysqL账户的home目录下，设置执行权限
cp MysqL.sh /home/MysqL/MysqL.sh
chmod 777 /home/MysqL/MysqL.sh


su - MysqL -c ./MysqL.sh

六：MysqL.sh

#7.安装mysl数据库
cd /usr/local/MysqL/scripts

./MysqL_install_db --datadir=/data/MysqLdata/3306/data --basedir=/usr/local/MysqL
