    使用一個腳本監控mysql進程

    進入 cd /backup
    如果沒mysql資料夾
    建立 mysql資料夾
    mkdir mysql
    然後
    nano /backup/mysql/mysql.sh

    #!/bin/sh
    ps -fe|grep mysqld |grep -v grep
    if [ $? -ne 0 ]
    then
    echo “start process….."
    service mysql start
    else
    echo “runing….."
    fi

    DATE=`date +%Y%m%d%H%M%S`
    echo $DATE >> /backup/mysql/test.txt

    存檔

    nano /etc/crontab

    */1 * * * * root /backup/mysql/mysql.sh

    存檔

    crontab /etc/crontab

    然後更改檔案權限(這是 permission denied 解決方案)
    chmod 777 /backup/mysql
    chmod 777 /backup/mysql/mysql.sh

    備註:
    假如是 mariadb
    service mysql start 請修改成 systemctl restart mariadb

    [CentOS7]啟用網卡 

    若沒特別設定 CentOS7預設裝好網卡是沒有啟動的
    要啟動網卡先去修改/etc/sysconfig/network-scripts

    1. vi ifcfg-enp2s0(可能會有不同名稱,通常會是ifcfg-enxxxx)

    更改以下內容
    BOOTPROTO=none(改成固定IP)
    IPV6INIT=no(不使用IPv6)
    ONBOOT=yes(開機時啟動網卡)
    IPADDR=x.x.x.x
    NETMASK=255.255.255.0
    GATEWAY=x.x.x.254
    DNS1=8.8.8.8

    #systemctl restart network

    指定對外網卡方式

    1. vi /etc/sysconfig/network

    加入GATEWAYDEV=eth0 (你要對外的那一張網卡)
    這是將默認gateway設定用對外網卡

    #systemctl restart network
