centos docker ssh 登錄
使用ifconfig，需要安裝net-tools窃祝。
yum install -y net-tools
安裝openssl，openssh-server
yum install -y openssl openssh-server
/usr/sbin/sshd -D

[root@master /]# cd
[root@master ~]# ssh-keygen -q -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key -N ''
[root@master ~]# ssh-keygen -q -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ''
[root@master ~]# ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key -N ''
接著修改sshd_config文件配置信息踱侣，路徑為 /etc/ssh/sshd_config
1.將 Port 22 前面的注釋去掉
2.將 PermitRootLogin 的 no 改為 yes
重新啟動sshd:命令結(jié)尾加個‘&’粪小，自動后臺運行，啟動成功會返回進程號
[root@master ~]# /usr/sbin/sshd -D &
[root@master ~]# ps aux |grep sshd

root 73 0.0 0.0 9104 828 pts/1 S+ 17:53 0:00 grep --color=auto sshd
重新設(shè)置root密碼等
yum install passwd
[root@master ~]# passwd
Changing password for user root.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.

mongo 安裝
啟動
mongod --config /usr/local/mongo/etc/mongodb.conf
或者使用
systemctl start mongodb.service
mongodb 位置：/usr/local/mongodb
mongodb 配置：mongod --config /usr/local/mongo/etc/mongodb.conf
dbpath=/usr/local/mongo/data/db # 指定數(shù)據(jù)存儲目錄
logpath=/usr/local/mongo/log/mongodb.log # 指定日志文件存儲目錄

Centos7升級openssl到1.1.1版本
一泻仙、升級openssl操作方法
1.1安裝telnet服務糕再，避免升級openssl和openssh導致主機不能遠程
1.2準備環(huán)境
yum install -y gcc gcc-c++ glibc make autoconf openssl openssl-devel pcre-devel pam-devel pam* zlib*
1.3下載openssl源碼包，我這里下載的版本是openssl-1.1.1g
wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz
1.4操作升級openssl
解壓：tar xf openssl-1.1.1g.tar.gz
進入openssl目錄：cd openssl-1.1.1g
編譯安裝：./config --prefix=/usr/local/openssl --openssldir=/etc/ssl --shared zlib
make -j4
make install
1.5備份當前的openssl
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl /usr/include/openssl.bak
1.6配置使用新版本
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
查看是否創(chuàng)建成功：ll /usr/bin/openssl;ll /usr/include/openssl
1.7更新動態(tài)鏈接庫數(shù)據(jù)
echo “/usr/local/openssl/lib” >> /etc/ld.so.conf
1.8重新加載動態(tài)鏈接庫
/sbin/ldconfig
1.9驗證openssl版本
openssl version
解決openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory錯誤
ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
