从17年开始三年了，购买使用了不下十台vps，每次购买新的vps之后都需要对他进行初始化设置，很是繁琐，所以最近在写一个一键脚本，这样可以一键安装并设置所有需要的软件，方便了许多。目前脚本还没有完成，所以我先把初始化的这些步骤全部记录下来，既是方便自己，也可以为大家提供一份参考。
前期重要软件更新与安装
yum install nano git
yum update
ssh设置
首先打开sshd_config
nano /etc/ssh/sshd_config
首先将Port 22取消注释，然后添加一行 Port 1022。保存退出
再将sshd服务重启。
systemctl restart sshd
这时候使用ssh连接工具连接你设置的端口（我的是1022），如果成功连接，则可以重复上述步骤将Port 22一行注释掉，这样22端口就不会暴露出来，部分保证安全。如果不能连接，可以去服务器提供商控制面板找找有没有端口开放设置。
安全设置
创建一个目录名叫AutoTasks，新建一个脚本，名称为auto_block_failed_ip.sh
脚本内添加如下内容：
#! /bin/bash
cat /var/log/secure|awk '/Failed/{print $(NF-3)}'|sort|uniq -c|awk '{print $2"="$1;}' > /usr/local/bin/black.list
for i in `cat /usr/local/bin/black.list`
do
IP=`echo $i |awk -F= '{print $1}'`
NUM=`echo $i|awk -F= '{print $2}'`
if [ ${#NUM} -gt 1 ]; then
grep $IP /etc/hosts.deny > /dev/null
if [ $? -gt 0 ];then
echo "sshd:$IP:deny" >> /etc/hosts.deny
fi
fi
done
保存退出
chmod +x auto_block_failed_ip.sh
将脚本添加可执行权限。
crontab -e
# 然后添加如下一行
0 * * * * /bin/sh /root/AutoTasks/auto_block_failed_ip.sh
# 注意将地址改为你设置的地址
# 作用是每天0点执行一次 封禁多次尝试登录失败的ip
安装caddy前的准备
创建一个新目录：
mkdir /var/www
cd /var/www
git clone https://github.com/librespeed/speedtest
cd speedtest
mv example-singleServer-pretty.html index.html
rm -rf example-*
如果想要真正的测速服务器，请参考我的这篇文章。
安装caddy
请查看官方脚本进行设置。如下只是本文写成时官方的操作指南。
yum install yum-plugin-copr
yum copr enable @caddy/caddy
yum install caddy
创建一个Caddyfile
nano /etc/caddy/Caddyfile
# 粘贴如下内容
:80 {
root * /var/www/speedtest
file_server
reverse_proxy /mineray localhost:8888
}
启动caddy
systemctl enable caddy
systemctl start caddy
# 可以使用如下命令查看是否启动成功
systemctl status caddy
安装acme.sh
curl https://get.acme.sh | sh
执行下面的命令:
# 注意将下方的your.site.name改为你的域名地址。
mkdir -p /root/cert/sites/your.site.name
#首先在acme注册，使用自己的邮箱。
acme.sh --register-account -m [email protected]
./acme.sh --issue -d your.site.name --webroot /var/www/speedtest
./acme.sh --install-cert -d your.site.name \
--fullchain-file /root/cert/sites/your.site.name/your.site.name.crt \
--key-file /root/cert/sites/your.site.name/your.site.name.key \
--reloadcmd "systemctl restart caddy"
安装V2RAY
bash <(curl -L https://raw.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-release.sh)
# 安装最新发行的 geoip.dat 和 geosite.dat
bash <(curl -L https://raw.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-dat-release.sh)
脚本设置：
nano /usr/local/etc/v2ray/config.json
# 粘贴如下内容, 将clients里面的id改成自己的，可以在这里生成：
# https://www.uuidgenerator.net/

安装 Trojan

注意，Xray和上面的v2ray、trojan是互斥的，装了上面的，就不要装Xray了。

启用bbr
参考这篇文章
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
yum --enablerepo=elrepo-kernel install kernel-ml -y
rpm -qa | grep kernel
# 下面这句执行后选中需要的内核，从0开始排序
egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'
grub2-set-default 0
# 这里reboot
sudo modprobe tcp_bbr
echo "tcp_bbr" | sudo tee --append /etc/modules-load.d/modules.conf
echo "net.core.default_qdisc=fq" | sudo tee --append /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" | sudo tee --append /etc/sysctl.conf

sysctl net.ipv4.tcp_available_congestion_control
sysctl net.ipv4.tcp_congestion_control
lsmod | grep bbr
