這篇“CentOS下怎么使用OpenSSL編譯安裝OpenSSH”文章的知識點大部分人都不太理解,所以小編給大家總結了以下內容,內容詳細,步驟清晰,具有一定的借鑒價值,希望大家閱讀完這篇文章能有所收獲,下面我們一起來看看這篇“CentOS下怎么使用OpenSSL編譯安裝OpenSSH”文章吧。
# rpm -qa | grep openssh openssh# rpm -qa | grep openssh openssl
卸載用rpm -e 如果出現依賴包導致無法卸載,在最后面加上–nodeps即可,例:
# rpm -e openssl --nodeps
具體安裝過程如下:
http://ftp5.usa.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.3p1.tar.gz http://www.openssl.org/source/openssl-1.0.2j.tar.gz http://www.openssl.org/source/openssl-fips-2.0.13.tar.gz
# yum install -y zlib-devel pam-devel tcp_wrappers-devel
具體說明見 http://www.openssl.org/docs/fips ;
# tar zxpf openssl-fips-2.0.5.tar.gz# cd openssl-fips# ./config# make && make install
# tar zxpf openssl-1.0.1h.tar.gz# cd openssl-1.0.1h# ./config fips --shared# make && make install
# echo "/usr/local/ssl/lib" >> /etc/ld.so.conf# ldconfig
# tar zxpf openssh-6.6p1.tar.gz# cd openssh-6.6p1# ./configure \ --prefix=/usr \ --sysconfdir=/etc/ssh \ --with-md5-passwords \ --with-pam \ --with-tcp-wrappers \ --with-ssl-dir=/usr/local/ssl# make && make install# ssh -V
修改相關配置
# cp -p contrib/redhat/sshd.init /etc/init.d/sshd (此處的contrib路徑為解壓后的OpenSSH包路徑)# chmod u+x /etc/init.d/sshd (加執行權限)# chkconfig --add sshd (增加sshd服務)# chkconfig sshd on (把sshd加入啟動項)# yum install openssh (安裝OpenSSH客戶端)# vim /etc/ssh/sshd_configPermitRootLogin yes #允許root賬戶登錄,單root賬戶必須加上,其他的參數請自行修改
# /etc/init.d/sshd startssh-keygen: illegal option -- A Usage: ssh-keygen [options] Options: -a trials Number of trials for screening DH-GEX moduli. -B Show bubblebabble digest of key file. -b bits Number of bits in the key to create. -C comment Provide new comment. -c Change comment in private and public key files. -e Convert OpenSSH to IETF SECSH key file. -F hostname Find hostname in known hosts file. -f filename Filename of the key file. -G file Generate candidates for DH-GEX moduli. -g Use generic DNS resource record format. -H Hash names in known_hosts file. -i Convert IETF SECSH to OpenSSH key file. -l Show fingerprint of key file. -M memory Amount of memory (MB) to use for generating DH-GEX moduli. -N phrase Provide new passphrase. -P phrase Provide old passphrase. -p Change passphrase of private key file. -q Quiet. -R hostname Remove host from known_hosts file. -r hostname Print DNS resource record. -S start Start point (hex) for generating DH-GEX moduli. -T file Screen candidates for DH-GEX moduli. -t type Specify type of key to create. -v Verbose. -W gen Generator to use for generating DH-GEX moduli. -y Read private key file and print public key. Starting sshd: [ OK ]
sshd文件的ssh-keygen參數有問題,暫時不知道怎么解決,但是不影響使用。
