linux下apache安装ssl步骤

制作证书:

             参考:linux下运用opensll制作ssl证书

            生成三个证书 server.crt 、server-ca.crt、server.key

安装openssl

tar -xzvf openssl-1.0.2h.tar.gz
cd openssl-1.0.2h
./config -fPIC  enable-shared
make depend
make  && make install
make clean && make distclean

#openssl类库做软连接
ln -s /usr/local/ssl//lib/*.so.* /usr/lib64
ln -s /usr/local/ssl//lib/*.so.* /usr/lib

安装apache

     apache依赖包安装不详细说明,

tar xvzf httpd-2.4.18.tar.gz 
cd httpd-2.4.18
./configure \
    --prefix=/usr/local/cp-httpd-2.4.18 \
	--with-apr=/usr/local/cp-apr-1.5.2 \
	--with-apr-util=/usr/local/cp-apr-util-1.5.4 \
	--with-apr-iconv=/usr/local/cp-apr-iconv-1.2.1 \
	--with-ssl=/usr/local/ssl \
	--enable-so \
	--enable-ssl \
	--enable-mods-shared=all \
	--enable-cache \
	--enable-disk-cache \
    --enable-file-cache \
    --enable-mem-cache 	
make && make install
make clean && make distclean

配置apache的ssl

httpd.conf中配置

#启用ssl模块
sed -i 's:#LoadModule ssl_module modules/mod_ssl.so:LoadModule ssl_module modules/mod_ssl.so:' /usr/local/httpd/conf/httpd.conf
sed -i 's:#LoadModule socache_shmcb_module modules/mod_socache_shmcb.so:LoadModule socache_shmcb_module modules/mod_socache_shmcb.so:' /usr/local/httpd/conf/httpd.conf
sed -i 's:#Include conf/extra/httpd-ssl.conf:Include conf/extra/httpd-ssl.conf:' /usr/local/httpd/conf/httpd.conf
httpd-ssl.conf配置
sed -i 's:#SSLCertificateChainFile "/usr/local/httpd/conf/server-ca.crt":SSLCertificateChainFile "/usr/local/httpd/conf/server-ca.crt":' /usr/local/httpd/conf/extra/httpd-ssl.conf
拷贝server.crt 、server-ca.crt、server.key到/usr/local/httpd/conf目录下

apache结合openssl安装过程中出现的错误

  • 1、apache错误提示libz.a: could not read symbols: Bad value”
                   重新安装openssl 加上-fPIC和enable-shared参数
         ./config -fPIC --prefix=/usr/local/openssl1.0.1  enable-shared
  • 2、apache的httpd.conf缺乏LoadModule ssl_module modules/mod_ssl.so解决方法

                  原因是上一次编译的缓存存,需要清除掉才能重新生成执行

         make clean && make distclean

3、httpd: Syntax error on line 129 of /usr/local/cp-httpd-2.4.18/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: libssl.so.1.0.0: cannot open shared object file: No such file or directory
         ln -s /usr/local/ssl/lib/*.so /usr/lib64
         ln -s /usr/local/ssl//lib/*.so.* /usr/lib

                  这个问题比较奇怪,命名在httpd安装中指定了--enable-ssl和--with-ssl=/usr/local/openssl/还是无法生效,httpd只在/usr/lib64查找libssl.so.1.0.0,因此需要做个软连接处理。

配置rewrite规则实现访问http自动跳转到https

实现方法是定义一个.htaccess放在httdocs中,内容为:


  Options +FollowSymlinks
  RewriteEngine On

  RewriteCond %{SERVER_PORT} !^443$
  RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
 
  ErrorDocument 404 /404.html
  ErrorDocument 403 /404.html

特别说明:

     apache重新编译不会覆盖原有的httpd.conf文件,因此如果原有没有编译ssl的话,httpd.conf中必须手工加上mod_ssl.so模块配置
