librenms.conf nginx配置
server {

server_name librenms.XXX.com;
root /opt/librenms/html/;
index index.php;

observium.conf nginx配置
server {
listen 80;
root /opt/observium/html/;
index index.php;
server_name observium.XXX.com;
error_log /var/log/nginx/observium.error.log ;
access_log /var/log/nginx/observium.log ;

observium.sh 升级迭代版本
cd /opt
mv observium observium_old
wget http://www.observium.org/observium-community-latest.tar.gz -O -|tar xz
mv /opt/observium_old/{rrd,logs,config.php} /opt/observium/
/opt/observium/discovery.php -u
/opt/observium/discovery.php -h all
rm -rf observium_old
大致先更换vault源，然后执行切换升级。
# CentOS 8
minorver=8.5.2111
sudo sed -e "s|^mirrorlist=|#mirrorlist=|g" \

-i.bak \
/etc/yum.repos.d/CentOS-*.repo
然后dnf更新系统。
dnf install centos-release-stream -y
dnf swap centos-linux-repos centos-stream-repos -y
dnf distro-sync -y
可能有一些第三方包不能升级， 也有可能遇上centos-release-stream安装失败的情况。

用brew安装的mtr安装或多或少的会有一些问题，直接下载pkg来安装来的方便一些。

因为攻击原因UDP协议禁用了后影响到DNS解析了.
echo "options use-vc" >> /etc/resolv.conf
use-vc (since glibc 2.14)
Sets RES_USEVC in _res.options. This option forces
the use of TCP for DNS resolutions.

为了兼容老旧的solusvm进行系统管理, 最近更新fedora的系统模版发现官方已经抛弃原来的配置方式了.
解决方案如下
dnf remove NetworkManager -y
dnf install network-scripts -y
systemctl enable network
然后重新写入/etc/sysconfig/network-scripts/ifcfg-eth0的配置内容.
另外nmcli的网卡配置文件目录/etc/NetworkManager/system-connections/下面有eth0.nmconnection之类的文件保存着IP配置信息.

ipxe默认ZLIB GZIP IMAGE_COMBOOT所以自己编译一下, 编译EFI版本的时候要去掉IMAGE_COMBOOT.
还有通过EMBED预置脚本编译成iso后, 在没有dhcp的机器上也可以进行ipxe引导.
cat>/opt/tftp/boot.ipxe<<EOF
#!ipxe
isset ${ip} || dhcp || config
ifopen
show mac
route
chain --autofree http://你的pxe服务器地址/ipxe.php
EOF
cd /tmp
yum install git mkisofs gcc make xz-devel -y
git clone git://git.ipxe.org/ipxe.git
cd ipxe/src
cat>config/local/general.h<<EOF
#define DOWNLOAD_PROTO_HTTPS
#define IMAGE_COMBOOT
#define CONSOLE_CMD
#define VLAN_CMD
#define IMAGE_ZLIB
#define IMAGE_GZIP
EOF
make EMBED=/opt/tftp/boot.ipxe
cat>config/local/general.h<<EOF
#define DOWNLOAD_PROTO_HTTPS
#define CONSOLE_CMD
#define VLAN_CMD
#define IMAGE_ZLIB
#define IMAGE_GZIP
EOF
make bin-x86_64-efi/{ipxe.efi,snponly.efi} EMBED=/opt/tftp/boot.ipxe
install -p -D -m 0644 bin/{undionly.kpxe,undionly.kkpxe} /opt/tftp/
install -p -D -m 0644 bin-x86_64-efi/{ipxe.efi,snponly.efi} /opt/tftp/
还有 bin/ipxe.iso bin/ipxe.lkrn bin/ipxe.pxe bin/ipxe.usb可以复制一下, 做ipxe网络启动只要一个ipxe.efi和snponly.efi 以及ipxe.kkpxe就够了
最近在写自动装机管理, 等写完了才在github上发现一个项目https://github.com/OneB1t/uefihttpboot
当时要是多留个心, 也不至于后面走了很多弯路.

最近折腾得比较头大
准备工作先建立一个web服务.
将esxi的iso下载解压并将boot.cfg配置修改好
#自定义内容
esxiurl=http://$sesrver/VMware-VMvisor-Installer-6.5.0.XXXX.x86_64.iso
isoname=VMware_esxi.iso
tmppath=tmp
isocache=esxipath
#-------------------------------------------------------------------------------------
mkdir $isocache $tmppath
wget -c $esxiurl -O $isoname
mount $isoname $tmppath
rsync -az $tmppath/ $isocache/
umount $tmppath
sed -i 's#/##g' $isocache/boot.cfg
sed -i 's/prefix/#prefix/g' $isocache/boot.cfg
sed -i 's/kernelopt/#kernelopt/g' $isocache/boot.cfg
kickstart文件也可以一起丢到esxi的web目录下面
ipxe默认没有开启支持SYSLINUX COMBOOT,需要自己编译进去
yum install git mkisofs gcc make rsync
git clone git://git.ipxe.org/ipxe.git
cd ipxe/src
cat>>config/local/general.h<<EOF
#define DOWNLOAD_PROTO_HTTPS
#define IMAGE_COMBOOT
EOF
make bin/{ipxe.iso,undionly.kkpxe,ipxe.usb} bin-x86_64-efi/ipxe.efi
mkdir ipxe
cp bin/{ipxe.iso,undionly.kkpxe,ipxe.usb} bin-x86_64-efi/ipxe.efi ipxe
编译好的undionly.kkpxe放到tftp目录下, 然后dhcp引导加载
IPXE脚本部分:
#!ipxe
iseq ${platform} efi && goto is_efi ||
kernel {$mirror}/mboot.c32 -c {$mirror}/boot.cfg ks=http://{$server}/kickstart prefix={$mirror} nameserver={$dns} BOOTIF={$mac} ip={$ip} netmask={$netmask} gateway={$gateway} kernelopt=allowLegacyCPU=true
boot
:is_efi
kernel {$mirror}/efi/boot/bootx64.efi -c {$mirror}/boot.cfg ks=http://{$server}/kickstart prefix={$mirror} nameserver={$dns} BOOTIF={$mac} ip={$ip} netmask={$netmask} gateway={$gateway} kernelopt=allowLegacyCPU=true
boot
{$mirror}是esxi的iso解压出来可以http访问的地址
这里特别感谢https://blog.open4j.com/2019/05/30/ipxe-build-embedded-script/ 点破了COMBOOT的问题.
yum install git autoconf automake gcc libtool -y
git clone https://github.com/bgp/bgpq4
cd bgpq4
./bootstrap
./configure
make
make install
编译好后从as-set抓取IP直接生成配置
bgpq4 -Jl Baidu-list AS-55967
具体用法参考github上项目的说明文件.
虽然有第三方的,但是自己nginx里面写死配置来得安稳些.

弃用ntp换chrony做时间同步了
cat /usr/share/zoneinfo/Asia/Shanghai>/etc/localtime
yum install -y chrony
systemctl enable chronyd
systemctl start chronyd
Centos8(Caddy2)
yum -y -q install epel-release
yum -y copr enable @caddy/caddy
yum -y -q install caddy
/etc/caddy/Caddyfile的typecho配置例子
DOMAIN='blog.domian'
cat>/etc/caddy/Caddyfile<<EOF
${DOMAIN}, www.${DOMAIN}
{
tls [email protected]${DOMAIN}
root * /home/${DOMAIN}/
encode gzip
file_server
php_fastcgi unix//dev/shm/php-fpm.sock
handle_path / { try_files {path} {path}/index.php?{query} index.php?{query} }
}
EOF
“域名.后缀” 替换成自己的域名
/dev/shm/php-fpm.sock换成自己的php-fpm路径
多个域名用逗号和空格隔开, 可以绑定多个域名.
php自己安装配置, Caddyfile配置已经验证可用.
用caddy自动续签ssl太爽了, 之前编译安装太费心了,现在可以直接从epel安装.
但是如果要做4层协议转发,还是没有nginx效率强大.
Centos7
yum -y -q install epel-release
yum -y -q install caddy
