SilverLight's questions

看看所有的 openconnect 版本和这个。

sudo yum remove ocserv
wget ftp://ftp.infradead.org/pub/ocserv/ocserv-0.12.3.tar.xz
mkdir /usr/local/ocserv
tar xvf ocserv-0.12.3.tar.xz -C /usr/local/ocserv
cd /usr/local/ocserv/ocserv-0.12.3
sudo ./configure && make && make check
sudo make install

就这样yum remove ocserv告诉No Match for argument: ocserv。
并以这种方式sudo systemctl start ocserv告诉Failed to start ocserv.service: Unit not found.

wget https://kojipkgs.fedoraproject.org//packages/ocserv/0.12.3/1.el7/x86_64/ocserv-0.12.3-1.el7.x86_64.rpm
yum localinstall ocserv-0.12.3-1.el7.x86_64.rpm

查看所有 openconnect 版本。
现在我想安装ocserv-0.12.3.tar.xz在 CentOS 7 机器上。

对于安装（tar.xz）包我做了这些命令，但没有安装：

sudo yum remove ocserv
wget ftp://ftp.infradead.org/pub/ocserv/ocserv-0.12.3.tar.xz
mkdir /usr/local/ocserv
tar xvf ocserv-0.12.3.tar.xz -C /usr/local/ocserv
cd /usr/local/ocserv/ocserv-0.12.3
sudo ./configure && make && make check
sudo make install

我做错了什么？
在 CentOs 7 上安装 (tar.xz) 软件包的正确方法是什么？

[root@Hamoon ocserv-0.12.3]# sudo ./configure

To many yes during ./configure

看看所有的 openconnect 版本和这个。

在 CentOs 7 上安装 openconnect(ocserv-0.12.3) 软件包的正确方法是什么？

我尝试了这些命令：

sudo yum -y install epel-release
sudo yum repolist enabled
sudo yum info ocserv

但它显示的是 0.12.2 版，而不是 0.12.3 版！
现在我该如何安装 0.12.3 版？

我有 centos 7.6 并在上面安装了 squid 4.5。

sudo yum -y install squid

我关注了这个链接。 没有身份验证 squid 可以正常工作。这是添加部分 后的 squid.conf ：Basic Authentication

请看# Basic Authentication部分。
问题是：
/usr/lib64/squid/basic_ncsa_auth文件不存在。
那个文件在哪里？
我该如何解决这个问题？

Description : Squid is a high-performance proxy caching server for Web clients,
            : supporting FTP, gopher, and HTTP data objects. Unlike traditional
            : caching software, Squid handles all requests in a single,
            : non-blocking, I/O-driven process. Squid keeps meta data and especially
            : hot objects cached in RAM, caches DNS lookups, supports non-blocking
            : DNS lookups, and implements negative caching of failed requests.
            :
            : Squid consists of a main server program squid, a Domain Name System
            : lookup program (dnsserver), a program for retrieving FTP data
            : (ftpget), and some management and client tools.

我在 centos 7.6 上安装了 stunnel 4.5。

sudo yum -y install stunnel

现在我想在 centos 7.6 上将 stop-start-restart-status stunnel 作为服务。
下面的命令不起作用：

systemctl start stunnel

我怎样才能做到这一点？

stunnel /etc/stunnel/stunnel.conf

作品。
但是命令

kill `cat /var/run/stunnel/stunnel.pid`

不起作用。它告诉：

cat: /var/run/stunnel/stunnel.pid: 没有这样的文件或目录

编辑：
这是stunnel.conf我在此路径（/etc/stunnel/stunnel.conf）中创建的文件。

client = no
[squid]
accept  = 1800
connect = 127.0.0.1:8080
cert = /etc/stunnel/stunnel.pem

它工作正常。
