## 安装 ##

#!/bin/sh
    
    DIR=`pwd`
    KEEPALIVED_USR_DIR=/usr/local/keepalived
    KEEPALIVED_DIR=/usr/local/keepalived-1.2.18
    CONF=/etc/keepalived/keepalived.conf
    CONF_BAK=/etc/keepalived/keepalived.conf.bak
    CHECK=/etc/keepalived/onos_check.sh
    CHECK_BAK=/etc/keepalived/onos_check.sh.bak
    CHECK_REQ=/etc/keepalived/onos_check_req.sh
    CHECK_REQ_BAK=/etc/keepalived/onos_check_req.sh.bak
    
    
    echo "-----------------------------------install keepalived-------------------------------"
    
    if [ -d $KEEPALIVED_DIR ]; then
        echo "keepalived has installed"
        # 替换配置文件
        ## 备份原来的文件和检查脚本
        mv -f $CONF $CONF_BAK
        mv -f $CHECK $CHECK_BAK
        mv -f $CHECK_REQ $CHECK_REQ_BAK
        ## 拷贝新文件
        cd $DIR
        cp -f ./keepalived/keepalived.conf $CONF
        chmod 777 ./keepalived/onos_check.sh
        chmod 777 ./keepalived/onos_check_req.sh
        # cp -f ./keepalived/onos_check.sh $CHECK
    
        # 重启数据库
        service keepalived restart
        exit 3
    fi
    
    ## 解压keepalived.tar.gz
    cd $DIR
    mkdir -p $KEEPALIVED_DIR
    tar -vxf keepalived-1.2.18.tar.gz -C $KEEPALIVED_DIR --strip-components 1
    
    ## 编译keepalived
    cd $KEEPALIVED_DIR && ./configure --prefix=$KEEPALIVED_USR_DIR
    make && make install
    
    ## 将keepalived制作成系统服务
    ### 首先创建文件夹，将keepalived配置文件进行复制
    mkdir -p /etc/keepalived
    
    cd $DIR
    ### 复制配置文件
    # cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
    cp -f ./keepalived/keepalived.conf /etc/keepalived/
    ### 检查脚本复制
    chmod 777 ./keepalived/onos_check.sh
    #### 先不把检查脚本复制，等onos启动之后再复制过去
    #cp onos_check.sh $CHECK
    
    ### 然后复制keepalived脚本文件
    cp -f /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
    cp -f /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
    ln -sf /usr/local/sbin/keepalived /usr/sbin/
    ln -sf /usr/local/keepalived/sbin/keepalived /sbin/
    
    ### 设置开机启动
    chkconfig keepalived on
    
    ### 解决启动报错
    cd /usr/sbin/
    rm -f keepalived
    cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
    
    echo "-----------------------------------install keepalived success-------------------------------"
    
    service keepalived start
    
    cd $DIR

## 卸载 ##

#!/bin/sh
    
    service keepalived stop
    
    rm -rf /usr/local/keepalived
    rm -rf /usr/local/keepalived-1.2.18
    rm -rf /etc/keepalived
    rm -rf /etc/init.d/keepalived
    rm -rf /etc/sysconfig/keepalived
    rm -rf /usr/local/sbin/keepalived
    rm -rf /usr/sbin/keepalived
    rm -rf /sbin/keepalived
