1. 镜像下载

官方下载链接: https://www.centos.org/download/

2. 网络配置

[root@localhost root]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
ONBOOT=no —> ONBOOT=yes
[root@localhost root]# systemctl restart network

2.1 NAT模式

2.2 Host-Only

3. yum源

[root@localhost root]# ll /etc/yum.repos.d/
total 44
-rw-r--r--. 1 root root 1572 Dec  1  2016 CentOS-Base.repo
...

这里以网易Yum源为例。

1. mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2. wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
3. yum clean all && yum makecache

4. 常用软件

sudo yum install net-tools
sudo yum install openssh-server
sudo yum install make
sudo yum install git
sudo yum install gdb
sudo yum install cmake
sudo yum install gcc
sudo yum install wget
sudo yum install tcpdump
sudo yum install vim
sudo yum install tree
sudo yum list mariadb*
sudo yum install mariadb-server
sudo yum install libcurl-devel
sudo yum install libstdc++-devel
sudo yum install jansson-devel
sudo yum install gcc-c++
sudo yum install rpm-build
sudo yum install mariadb-devel
sudo yum install java-1.8.0-openjdk
sudo yum install nmap-ncat
sudo yum install cloc
sudo yum install autoconf
sudo yum install pcre pcre-devel
sudo yum install lsof
sudo yum install ntpdate
sudo yum install rpmdevtools
sudo yum install nss-devel libcap-ng-devel
sudo yum install libxml2-devel

5. 更新时间

ntpdate time.windows.com

6. git配置

[root@localhost root]# git config --global user.name "root"
[root@localhost root]# git config --global user.email "root@root.com"
[root@localhost root]# git config --global color.ui true
[root@localhost root]# git config --global alias.st status
[root@localhost root]# git config --global credential.helper store
[root@localhost root]# git config --list
user.name=root
user.email=root@root.com
color.ui=true
alias.st=status
credential.helper=store

7. Go配置

1. 环境下载

[root@localhost root]# wget https://dl.google.com/go/go1.14.3.linux-amd64.tar.gz

2. 修改进程path

[root@localhost root]# tar -C /usr/local -xzf go1.14.3.linux-amd64.tar.gz

3. 修改环境变量，添加customer.sh

[root@localhost root]# cat /etc/profile.d/customer.sh
export GOROOT=/usr/local/go
export GOPATH=/workspace/golang
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

4. 修改动态库搜索目录

[root@localhost /]# cat /etc/ld.so.conf.d/customer.conf 
/usr/lib64/
[root@localhost /]# ldconfig

8. mysql配置

[root@localhost root]# systemctl start mariadb
[root@localhost root]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@localhost root]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.

[root@localhost root]# ss -nultp | grep 3306

9. Mac免密登陆Centos

参考链接

1. 生成密钥

ssh-keygen -t rsa -b 4096

2. 查看密钥

cat ~/.ssh/id_rsa.pub

3. 设置环境变量

export PUBKEYPATH="$HOME/.ssh/id_rsa.pub"
export USER_AT_HOST="taozhihao@localhost"

4. 密钥拷贝

ssh-copy-id -i "$PUBKEYPATH" "$USER_AT_HOST" -p 2224

5. 免密登陆

ssh -p 2224 taozhihao@localhost

10. 编译git遇到错误

[root@localhost git-2.9.5]# make all doc info
    SUBDIR perl
/usr/bin/perl Makefile.PL PREFIX='/usr' INSTALL_BASE='' --localedir='/usr/share/locale'
Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 3.
BEGIN failed--compilation aborted at Makefile.PL line 3.
make[1]: *** [perl.mak] Error 2
make: *** [perl/perl.mak] Error 2
[root@localhost git-2.9.5]# yum install perl-ExtUtils-MakeMaker

11. 创建新用户名和密码

[root@localhost ~]# adduser test

11.1 简单密码设置

[root@localhost ~]# cat /etc/pam.d/system-auth | grep password
#password    requisite     pam_pwquality.so try_first_pass local_users_only retry=3 authtok_type=
#password requisite pam_cracklib.so try_first_pass retry=3 minlen=8 dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 enforce_for_root reject_username
#password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
#password    sufficient    pam_sss.so use_authtok
#password    required      pam_deny.so
password sufficient pam_unix.so nullok md5 shadow

12. DNS

• 查看DNS配置

[root@localhost ~]# cat /etc/resolv.conf

• 添加静态DNS

[root@sec-eva-server00 taozhihao]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.1       www.test.com

13. 服务

• 查看服务列表

systemctl list-unit-files --type=service

• 重新加载某个服务的配置文件

systemctl daemon-reload
