Percona-Server-5.5.33二进制安装
一、删除percona server1.关闭mysqldservice mysqld stop，再删除 rm -rf /etc/my.cnf
2.删除rm -rf /usr/local/Percona-Server-5.5.33-rel31.1-566.Linux.x86_64文件夹
3.删除软链接 rm -rf /usr/local/mysql
4.chkconfig --del mysqld
删除rm -rf /etc/init.d/mysqld
5.删除mysql用户，和组 /usr/sbin/userdel mysql
6.去掉环境变量
# cat uninstall.sh
#!/bin/bash
/sbin/service mysqld stop &&
/bin/rm -rf /etc/my.cnf &&
/bin/rm -rf /usr/local/Percona-Server-5.5.33-rel31.1-566.Linux.x86_64 &&
/bin/rm -rf /usr/local/mysql &&
/sbin/chkconfig --del mysqld &&
/bin/rm -rf /etc/init.d/mysqld &&
/usr/sbin/userdel mysql
二、自动安装
说明：
1.将二进制percona文件：Percona-Server-5.5.33-rel31.1-566.Linux.x86_64.tar.gz拷贝到 /usr/local目录中
2.基本的目录（percona解压文件软连接到/usr/local/mysql）：
MYSQL_DIR="/usr/local"
DATA_DIR="/usr/local/mysql/data"
BASE_DIR="/usr/local/mysql"
3.将脚本拷贝到/root目录下，赋执行权限直接执行就好了
4.需要增加判断，是否已经安装有mysql了，安装过就直接退出了
# cat mysqinstall.sh
#!/bin/bash
MYSQL_DIR="/usr/local"
DATA_DIR="/usr/local/mysql/data"
BASE_DIR="/usr/local/mysql"
echo "-------checking mysql ENV now! please wait-------"
username=`cat /etc/passwd|grep mysql|cut -c 1-5`
if [[ $username == "mysql" ]];then
echo "user check,mysql user already have,can not install mysql!!"
else
echo "please input mysql version:"
read VERSION
echo"your mysql version is Percona-Server-$VERSION-rel31.1-566.Linux.x86_64.tar.gz"
if [ -e "$MYSQL_DIR/Percona-Server-$VERSION-rel31.1-566.Linux.x86_64.tar.gz" ]
then
echo "Please waitting"
sleep 3
/usr/sbin/groupadd mysql &&
/usr/sbin/useradd -r -g mysql mysql &&
tar zxvf $MYSQL_DIR/Percona-Server-$VERSION-rel31.1-566.Linux.x86_64.tar.gz -C $MYSQL_DIR/ &&
cd $MYSQL_DIR/Percona-Server-$VERSION-rel31.1-566.Linux.x86_64 &&
echo "PATH=$PATH:$HOME/bin:/usr/local/mysql/bin" >> /root/.bash_profile && source /root/.bash_profile
ln -s $MYSQL_DIR/Percona-Server-$VERSION-rel31.1-566.Linux.x86_64 $MYSQL_DIR/mysql &&
cd $MYSQL_DIR/mysql &&
/bin/chown -R mysql . &&
/bin/chgrp -R mysql . &&
sh /usr/local/mysql/scripts/mysql_install_db --user=mysql
/bin/chown -R root . &&
/bin/chown -R mysql data
/bin/cp $BASE_DIR/support-files/my-medium.cnf /etc/my.cnf
/bin/cp $BASE_DIR/support-files/mysql.server /etc/init.d/mysqld
/sbin/chkconfig --add mysqld
/sbin/service mysqld start
else
echo "Your input mysql versionis not in $MYSQL_DIR"
