MYSQL 5.1自动安装脚本

    因为经常会涉及到部署mysql到各个环境（正式、性能、测试等），因此将安装步骤写成shell脚本，减少重复的工作   
    下面是一个自动化安装mysql 5.1.63的脚本，贴上来，大家可以下载my.cnf文件解压后和脚本放统一目录下，执行安装脚本就可以了。
做一下备忘,脚本内容如下：

#!/bin/bash
echo "-----------------------start install mysql----------------------"
yum -y install gcc gcc-c++ ncurses ncurses-devel openssl openssl-devel libtool*
mkdir -p /data/dbdata
if [ `grep "mysql" /etc/passwd | wc -l` -eq 0 ];then
echo "adding user mysql"
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
else
echo "mysql user is exist"
fi
wget
echo "tar xzvf mysql-5.1.63.tar.gz"
tar xzvf mysql-5.1.63.tar.gz
cd mysql-5.1.63
echo "configuring mysql,please wait-----------------"
./configure  '--prefix=/usr/local/mysql' '--localstatedir=/data/dbdata/' '--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock' '--with-charset=utf8' '--with-extra-charsets=complex' '--with-pthread' '--enable-thread-safe-client' '--with-ssl' '--with-client-ldflags=-all-static' '--with-mysqld-ldflags=-all-static' '--with-plugins=partition,federated,innobase,csv,blackhole,myisam,innodb_plugin,heap,archive' '--enable-shared' '--enable-assembler'

if [ $? -ne 0 ];then
echo "configure filed ,please check it out!"
exit 1
fi

echo "make mysql, please wait for 20 minutes"
make
if [ $? -ne 0 ];then
echo "make filed ,please check it out!"
exit 1
fi

make install

chown -R mysql:mysql /usr/local/mysql
chown -R mysql.mysql /data/dbdata/

/usr/local/mysql/bin/mysql_install_db --user=mysql

cp ../my.cnf /etc/my.cnf

cp /usr/local/mysql/share/mysql/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 2345 mysqld on

echo "mysql starting"
/etc/rc.d/init.d/mysqld start
if [ $? -ne 0 ];then
echo "mysql start filed ,please check it out!"
else
echo "mysql start successful,congratulations!"
fi

my.cnf的压缩附件如下：
