shell 安裝MYSQL

一、安裝腳本
 #!/bin/bash

MYSQL_HOME=/usr/local/mysql
# 將你的mysql安裝程序解壓後的文件名設置爲MYSQL_DIR，將安裝程序(mysql-xxx.tar.gz)放到當前目錄
MYSQL_DIR=mysql-standard-5.0.20-linux-i686-glibc23
MYSQL_DIR_OLD=$PWD/${MYSQL_DIR}
MYSQL_DIR_NEW=/usr/local/${MYSQL_DIR}
MYSQL_SOURCE=$MYSQL_DIR_OLD.tar.gz

if [ ! -f ${MYSQL_SOURCE} ]
then
    echo "MySQL package not found!"
    exit 1
fi

id mysql > /dev/null 2>&1
if [ $? -eq 1 ]
then
    # If user mysql does not exist,
    # delete group mysql fisrt if exists
    sed -i '/^mysql/d' /etc/group
    echo "Add group mysql"
    groupadd mysql
    echo "Add user mysql"
    useradd -g mysql mysql
fi

echo "Unzip MySQL-5.0.20"
tar zxvf ${MYSQL_SOURCE} > /dev/null 2>&1

echo "Move MySQL to the right place"
mv ${MYSQL_DIR_OLD} ${MYSQL_DIR_NEW}

echo "Create mysql linkage"
ln -s ${MYSQL_DIR_NEW} ${MYSQL_HOME}

echo "Change mysql directory to the right user and group"
cd $MYSQL_HOME
chown -R root  .
cd $MYSQL_HOME
chown -R mysql data
cd $MYSQL_HOME
chgrp -R mysql .

echo "Create mysql system database"
$MYSQL_HOME/scripts/mysql_install_db --user=mysql > /dev/null

echo "Set environment PATH"
sed -i '/export PATH=\/usr\/local\/mysql\/bin:$PATH/d' /etc/profile
echo 'export PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile
. /etc/profile

echo "Set mysql as system service"
cp $MYSQL_HOME/support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
/etc/init.d/mysql start

echo -n "Please input password of mysql user root: "
stty -echo
read ROOT_PASSWORD
stty echo
echo

if [ -z $ROOT_PASSWORD ]
then
    echo "ERROR: The password is null!"
    exit 1
fi

mysqladmin -uroot password "$ROOT_PASSWORD"
mysql -uroot -p$ROOT_PASSWORD -e"grant all on *.* to root@localhost identified by '$ROOT_PASSWORD'"
if [ $? -eq 0 ]
then
    echo "Set mysql user root password successfully!"
fi

二、卸載腳本
#!/bin/bash

MYSQL_HOME=/usr/local/mysql
# 將你的mysql安裝程序解壓後的文件名設置爲MYSQL_DIR
MYSQL_DIR=mysql-standard-5.0.20-linux-i686-glibc23
MYSQL_DIR_NEW=/usr/local/${MYSQL_DIR}

echo "Kill mysql demon"
pkill mysql > /dev/null 2>&1
echo "Clean mysql from PATH"
sed -i '/export PATH=\/usr\/local\/mysql\/bin:$PATH/d' /etc/profile

chkconfig mysql off
rm -f /etc/init.d/mysql
rm -f /etc/rc2.d/*mysql
rm -f /etc/rc3.d/*mysql
rm -f /etc/rc4.d/*mysql
rm -f /etc/rc5.d/*mysql
rm -f /etc/rc6.d/*mysql

echo "Remove mysql source file"
rm -rf ${MYSQL_HOME}
rm -rf ${MYSQL_DIR_NEW}

echo "Remove user mysql"
sed -i '/^mysql/d' /etc/group
sed -i '/^mysql/d' /etc/passwd

三、安裝成功後，運行. /etc/profile將mysql路徑添加進去
