Bash脚本更新ssl.conf中ssl证书文件的路径

我正在创建一个可重用的脚本，用于自动在服务器设置中设置新的SSL.我有几行需要更新文件路径.

I am creating a reusable script for automating the setup of new SSLs on server setups. I have a few different lines that need to get the file paths updated.

ssl.conf文件中的默认值如下所示(一个带有#号):

The defaults in the ssl.conf file look like this (One has leading # tag):

SSLCertificateFile /etc/pki/tls/certs/localhost.crt

我需要在bash脚本中对其进行动态设置，以使其最终像这样:

I need it to be dynamically set in the bash script, to end up like this:

SSLCertificateFile /etc/pki/tls/certs/example.crt

到目前为止，我是从这个开始的，但是我不确定自己在做什么.

So far I started out with this, but i'm not sure what I'm doing.

~/update_ssl_conf.sh

代码:

#!/bin/bash
SSL_CONFIG_PATH="/etc/httpd/conf.d/ssl.conf"

SSL_DEFAULT_CERT_PATH="SSLCertificateFile /etc/pki/tls/certs/localhost.crt"
SSL_CERT_PATH="SSLCertificateFile /etc/pki/tls/certs/example.crt"
sed "s/.*\b$SSL_DEFAULT_CERT_PATH\b.*/$SSL_CERT_PATH/" $SSL_CONFIG_PATH

***更新区域，还需要sed命令来更新以#开头的行.

***UPDATED AREA, Also need sed command to update lines that begin with #.

ssl.conf文件中的默认值看起来像这样(带有#号标记):

The defaults in the ssl.conf file look like this (Has leading # tag):

#SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt

我需要在bash脚本中对其进行动态设置，以使其最终像这样:

I need it to be dynamically set in the bash script, to end up like this:

 SSLCACertificateFile /etc/pki/tls/certs/example-ca-bundle.crt

到目前为止，我是从这个开始的，但是我不确定自己在做什么.

So far I started out with this, but i'm not sure what I'm doing.

~/update_ssl_conf.sh

代码:

#!/bin/bash
SSL_CONFIG_PATH="/etc/httpd/conf.d/ssl.conf"

SSL_DEFAULT_CA_CERT_PATH="#SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt" 
SSL_CA_CERT_PATH="SSLCACertificateFile /etc/pki/tls/certs/example-ca-bundle.crt"

我尝试了接受的

sed -i "s|.*\b#$SSL_DEFAULT_CA_CERT_PATH\b.*|$SSL_CA_CERT_PATH|" SSL_CONFIG_PATH

和

sed -i "s|(?s).*(?<!\\w)$SSL_DEFAULT_CA_CERT_PATH(?!\\w).*|$SSL_CA_‌​CERT_PATH|" $SSL_CONFIG_PATH

都不起作用，因为正则表达式不正确.

neither are working because the regular expression is not correct.
