CentOS 7安裝完成后初始化的方法

更新時間：2016年10月26日 14:45:36 作者：shaonbean

這篇文章主要介紹了CentOS 7安裝完成后初始化的方法,本文分步驟給大家介紹的非常詳細，具有參考借鑒價值，需要的朋友可以參考下

1、添加用戶

新增名為"wang"的用戶

[root@vdevops ~]# useradd wang #添加賬戶
[root@vdevops ~]# passwd wang #設置密碼
Changing password for user wang.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@vdevops ~]# exit #退出
以用戶"wang"為例，設置其為唯一擁有管理員權(quán)限的賬戶
[root@vdevops ~]# usermod -G wheel wang
[root@vdevops ~]# vim /etc/pam.d/su
[html] view plain copy print?
#%PAM-1.0 
auth sufficient pam_rootok.so 
# Uncomment the following line to implicitly trust users in the "wheel" group. 
#auth sufficient pam_wheel.so trust use_uid 
# Uncomment the following line to require a user to be in the "wheel" group. 
# 取消下面一行的注釋 
auth required pam_wheel.so use_uid 
auth substack system-auth 
auth include postlogin 
account sufficient pam_succeed_if.so uid = 0 use_uid quiet 
account include system-auth 
password include system-auth 
session include system-auth 
session include postlogin 
session optional pam_xauth.so 
設置root賬戶的郵件轉(zhuǎn)發(fā)
# Person who should get root's mail
# 最后一行，取消注釋，改變用戶名稱
root: wang

2、設置防火墻和SELINUX

【1】防火墻

查看防火墻狀態(tài)

[root@vdevops ~]# systemctl status firewalld 
● firewalld.service - firewalld - dynamic firewall daemon 
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) 
Active: active (running) since Wed 2016-10-26 01:09:49 CST; 1h 36min ago 
Main PID: 744 (firewalld) 
CGroup: /system.slice/firewalld.service 
└─744 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid 
Oct 26 01:09:46 vdevops.com systemd[1]: Starting firewalld - dynamic firewall daemon... 
Oct 26 01:09:49 vdevops.com systemd[1]: Started firewalld - dynamic firewall daemon.

防火墻基本操作

[root@vdevops ~]# systemctl start firewalld #啟動防火墻 
[root@vdevops ~]# systemctl enable firewalld #設置防火墻開機自啟

默認情況下，“public”區(qū)域應用于NIC，dhcpv6-client和ssh是允許的。

當使用“firewall-cmd”命令操作時，如果輸入命令不帶“--zone = ***”規(guī)范，則配置設置為默認區(qū)域。

#顯示默認區(qū)域 
[root@vdevops ~]# firewall-cmd --get-default-zone 
public 
#顯示當前設置 
[root@vdevops ~]# firewall-cmd --list-all 
public (default, active) 
interfaces: eno16777736 
sources: 
services: dhcpv6-client ssh 
ports: 
masquerade: no 
forward-ports: 
icmp-blocks: 
rich rules: 
#顯示全部區(qū)域 
[root@vdevops ~]# firewall-cmd --list-all-zones 
block 
interfaces: 
sources: 
services: 
ports: 
masquerade: no 
forward-ports: 
icmp-blocks: 
rich rules: 

dmz 
interfaces: 
sources: 
services: ssh 
ports: 
masquerade: no 
forward-ports: 
icmp-blocks: 
rich rules: 
... 
#顯示特定區(qū)域允許的服務 
[root@vdevops ~]# firewall-cmd --list-service --zone=external 
ssh 
#改變默認區(qū)域 
[root@vdevops ~]# firewall-cmd --set-default-zone=external 
success 
#改變制定區(qū)域的接口 
[root@vdevops ~]# firewall-cmd --change-interface=eth1 --zone=external 
success 
#顯示制定區(qū)域的狀態(tài) 
[root@vdevops ~]# firewall-cmd --list-all --zone=external 
external (default, active) 
interfaces: eno16777736 eth1 
sources: 
services: ssh 
ports: 
masquerade: yes 
forward-ports: 
icmp-blocks: 
rich rules: 
#注：改變制定區(qū)域的接口，前提是次接口在當前系統(tǒng)是存在的

顯示默認定義的服務

[root@vdevops ~]# firewall-cmd --get-services 
RH-Satellite-6 amanda-client bacula bacula-client dhcp dhcpv6 dhcpv6-client dns freeipa-ldap freeipa-ldaps freeipa-replication ftp high-availability http https imaps ipp ipp-client ipsec iscsi-target kerberos kpasswd ldap ldaps libvirt libvirt-tls mdns mountd ms-wbt mysql nfs ntp openvpn pmcd pmproxy pmwebapi pmwebapis pop3s postgresql proxy-dhcp radius rpc-bind rsyncd samba samba-client smtp ssh telnet tftp tftp-client transmission-client vdsm vnc-server wbem-https 
#定義文件路徑如下，如果需要添加新的定義文件，在下面目錄添加相應的XML文件 
[root@vdevops ~]# ls /usr/lib/firewalld/services 
amanda-client.xml freeipa-ldap.xml ipp.xml libvirt.xml pmcd.xml RH-Satellite-6.xml tftp-client.xml 
bacula-client.xml freeipa-replication.xml ipsec.xml mdns.xml pmproxy.xml rpc-bind.xml tftp.xml 
bacula.xml ftp.xml iscsi-target.xml mountd.xml pmwebapis.xml rsyncd.xml transmission-client.xml 
dhcpv6-client.xml high-availability.xml kerberos.xml ms-wbt.xml pmwebapi.xml samba-client.xml vdsm.xml 
dhcpv6.xml https.xml kpasswd.xml mysql.xml pop3s.xml samba.xml vnc-server.xml 
dhcp.xml http.xml ldaps.xml nfs.xml postgresql.xml smtp.xml wbem-https.xml 
dns.xml imaps.xml ldap.xml ntp.xml proxy-dhcp.xml ssh.xml 
freeipa-ldaps.xml ipp-client.xml libvirt-tls.xml openvpn.xml radius.xml telnet.xml

添加或刪除允許的服務，重新啟動系統(tǒng)后，更改將恢復。如果永久更改設置，請?zhí)砑印?-permanent”選項。

#以添加http服務為例 
[root@vdevops ~]# firewall-cmd --add-service=http 
success 
[root@vdevops ~]# firewall-cmd --list-service 
http ssh 
#移除添加的http 
<pre name="code" class="html">[root@vdevops ~]# firewall-cmd --remove-service=http 
success 
[root@vdevops ~]# firewall-cmd --list-service 
ssh 
#添加http服務，永久生效 
[root@vdevops ~]# firewall-cmd --add-service=http --permanentsuccess
[root@vdevops ~]# firewall-cmd --reloadsuccess[root@vdevops ~]# firewall-cmd --list-servicehttp ssh

添加和移除端口

[root@vdevops ~]# firewall-cmd --add-port=465/tcp #添加端口 
success 
[root@vdevops ~]# firewall-cmd --list-port 
465/tcp 
[root@vdevops ~]# firewall-cmd --remove-port=465/tcp #移除端口 
success 
[root@vdevops ~]# firewall-cmd --list-port 
[root@vdevops ~]# firewall-cmd --add-port=465/tcp --permanent #添加端口，永久生效 
success 
[root@vdevops ~]# firewall-cmd --reload 
success 
[root@vdevops ~]# firewall-cmd --list-port 
465/tcp

加或刪除禁止的ICMP類型

[root@dlp ~]# firewall-cmd --add-icmp-block=echo-request #添加禁止回應請求 
success 
[root@dlp ~]# firewall-cmd --list-icmp-blocks 
echo-request 
[root@dlp ~]# firewall-cmd --remove-icmp-block=echo-request #移除添加的參數(shù) 
success 
[root@dlp ~]# firewall-cmd --list-icmp-blocks 
[root@dlp ~]# firewall-cmd --get-icmptypes #顯示ICMP支持的功能 
destination-unreachable echo-reply echo-request parameter-problem redirect 
router-advertisement router-solicitation source-quench time-exceeded

【2】如果不需要防火墻服務，關(guān)閉如下

[root@vdevops ~]# systemctl stop firewalld #停止防火墻服務 
[root@vdevops ~]# systemctl disable firewalld #禁止防火墻開機自啟 
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. 
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service. 
3、SELinux
[html] view plain copy print?
[root@vdevops ~]# getenforce #查看SELINUX工作模式 
Enforcing 
[root@vdevops ~]# sed -i 's/SELINUX=Enforcing/SELINUX=disabled/' /etc/selinux/config #禁用SELINUX 
[root@vdevops ~]# setenforce 0 #臨時禁用SELINUX，無需重啟

4、網(wǎng)絡設置

【1】、設置靜態(tài)IP和改變接口名稱

[root@vdevops ~]# nmcli c modify eno16777736 ipv4.addresses 10.1.1.56/24 #設置靜態(tài)IP 
[root@vdevops ~]# nmcli c modify eno16777736 ipv4.gateway 10.1.1.1 #設置網(wǎng)關(guān) 
[root@vdevops ~]# nmcli c modify eno16777736 ipv4.dns 10.1.1.1 #設置DNS 
[root@vdevops ~]# nmcli c modify eno16777736 ipv4.method manual #設置ipv4的類型為靜態(tài) 
[root@vdevops ~]# nmcli c down eno16777736;nmcli c up eno16777736 #重啟網(wǎng)絡接口 
Connection 'eno16777736' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/0) 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1) 
[root@vdevops ~]# nmcli d show eno16777736 #查看網(wǎng)絡接口狀態(tài) 
GENERAL.DEVICE: eno16777736 
GENERAL.TYPE: ethernet 
GENERAL.HWADDR: 00:0C:29:B6:F5:5E

valid_lft forever preferred_lft forever 
inet6 fe80::20c:29ff:feb6:f55e/64 scope link 
valid_lft forever preferred_lft forever

【2】禁用IPV6

[root@vdevops ~]# vim /etc/default/grub 
#第六行，添加 
GRUB_CMDLINE_LINUX="crashkernel=auto <span style="color:#FF0000;">ipv6.disable=1</span> rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet" 
[root@vdevops ~]# grub2-mkconfig -o /boot/grub2/grub.cfg 
Generating grub configuration file ... 
Found linux image: /boot/vmlinuz-3.10.0-327.36.2.el7.x86_64 
Found initrd image: /boot/initramfs-3.10.0-327.36.2.el7.x86_64.img 
Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64

done 
[root@vdevops ~]# reboot #重啟系統(tǒng)

【3】如果要將網(wǎng)絡接口名稱用作ethX，請按如下所示進行配置。

[root@vdevops ~]# vim /etc/default/grub 
#第六行添加 
GRUB_CMDLINE_LINUX="crashkernel=auto ipv6.disable=1 <span style="color:#FF0000;">net.ifnames=0</span> rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet 
[root@vdevops ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

done

4、服務設置

[1]、查看服務狀態(tài)

# 顯示正在運行的服務 
[root@vdevops ~]# systemctl -t service 
UNIT LOAD ACTIVE SUB DESCRIPTION 
auditd.service loaded active running Security Auditing Service 
avahi-daemon.service loaded active running Avahi mDNS/DNS-SD Stack 
crond.service loaded active running Command Scheduler

tuned.service loaded active running Dynamic System Tuning Daemon 
LOAD = Reflects whether the unit definition was properly loaded. 
ACTIVE = The high-level unit activation state, i.e. generalization of SUB. 
SUB = The low-level unit activation state, values depend on unit type. 
39 loaded units listed. Pass --all to see loaded but inactive units, too. 
To show all installed unit files use 'systemctl list-unit-files'. 
# 顯示所有服務 
[root@vdevops ~]# systemctl list-unit-files -t service 
UNIT FILE STATE 
auditd.service enabled 
autovt@.service disabled 
avahi-daemon.service enabled 
blk-availability.service disabled 
brandbot.service static

... 
systemd-user-sessions.service static 
systemd-vconsole-setup.service static 
teamd@.service static 
tuned.service enabled 
wpa_supplicant.service disabled 
125 unit files listed.

[2]、設置停止啟動自動的服務

[root@vdevops ~]# systemctl stop postfix #停止服務 
[root@vdevops ~]# systemctl disable postfix 
Removed symlink /etc/systemd/system/multi-user.target.wants/postfix.service. 
[root@vdevops ~]# systemctl start postfix 
[root@vdevops ~]# systemctl enable postfix 
Created symlink from /etc/systemd/system/multi-user.target.wants/postfix.service to /usr/lib/systemd/system/postfix.service. 
[root@vdevops ~]# systemctl status postfix 
● postfix.service - Postfix Mail Transport Agent 
Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled) 
Active: active (running) since Wed 2016-10-26 18:40:35 CST; 15s ago

Hint: Some lines were ellipsized, use -l to show in full.

[3]、還有一些SysV服務。它們由chkconfig控制，如下所示

[root@vdevops ~]# chkconfig --list 
Note: This output shows SysV services only and does not include native 
systemd services. SysV configuration data might be overridden by native 
systemd configuration. 
If you want to list systemd services use 'systemctl list-unit-files'. 
To see services enabled on particular target use 
'systemctl list-dependencies [target]'. 
netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off 
network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

5、更新系統(tǒng)添加其他源

yum update -y

添加其它源

添加一些有用的外部存儲庫來安裝有用的軟件

【1】安裝插件以向每個安裝的存儲庫添加優(yōu)先級。

[root@vdevops ~]# yum -y install yum-plugin-priorities 
# 設置官方源的優(yōu)先級為[priority=1] 
[root@vdevops ~]# sed -i -e "s/\]$/\]\npriority=1/g" /etc/yum.repos.d/CentOS-Base.repo

【2】添加從Fedora項目提供的EPEL存儲庫

[root@vdevops ~]# yum -y install epel-release 
# 設置優(yōu)先級[priority=5] 
[root@vdevops ~]# sed -i -e "s/\]$/\]\npriority=5/g" /etc/yum.repos.d/epel.repo 
# 可以通過設置enabled=0，來控制安裝軟件包時使用相應的源 
[root@vdevops ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/epel.repo 
# 如果[enabled=0], 使用下面命令安裝軟件包 
[root@vdevops ~]# yum --enablerepo=epel install [Package]

【3】添加CentOS SCLo軟件集合存儲庫。

[root@vdevops ~]# yum -y install centos-release-scl-rh centos-release-scl 
# 設置優(yōu)先級[priority=10] 
[root@vdevops ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo 
[root@vdevops ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo 
# 設置 [enabled=0] 
[root@vdevops ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo 
[root@vdevops ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo 
# 設置[enabled=0], 通過下面命令使用相應源 
[root@vdevops ~]# yum --enablerepo=centos-sclo-rh install [Package] 
[root@vdevops ~]# yum --enablerepo=centos-sclo-sclo install [Package]

【4】添加Remi的RPM存儲庫，它提供了許多有用的包

[root@vdevops ~]# yum -y install http://rpms.famillecollet.com/enterprise/remi-release-7.rpm 
# 設置優(yōu)先級 [priority=10] 
[root@vdevops ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/remi-safe.repo

6、配置特色的vim

【1】安裝vim

[root@vdevops ~]# yum -y install vim-enhanced

【2】設置別名

設置命令別名。（適用于以下所有用戶，如果您申請某個用戶，請在“〜/ .bashrc”中寫入相同的設置）

[root@dlp ~]# vi /etc/profile 
# 在最后添加下面一行內(nèi)容 
alias vi='vim' 
[root@dlp ~]# source /etc/profile #重載

或者

echo "alias vi='vim'" >> /etc/profile && source /etc/profile

【3】配置vim，針對所有用戶生效修改/etc/vimrc，針對特定用戶生效修改~/.vimrc

主要用語法高亮，插件使用，自動縮進等功能，本文不做詳細操作，后續(xù)會專門寫一篇關(guān)于優(yōu)化vim使用的博文，工欲善其事必先利其器

7、設置sudo

配置sudo以區(qū)分用戶的職責，如果一些人共享權(quán)限，必手動安裝sudo，因為它默認安裝，即使“最小安裝”

【1】設置普通用戶擁有root的所有權(quán)限

[root@vdevops ~]# visudo 
# 添加下面一行，使用戶“wang”擁有root的所有權(quán)限 
wang ALL=(ALL) ALL 
# 普通用戶使用root命令 
# 確保用戶為 'wang' 
[wang@vdevops ~]$ /usr/bin/cat /etc/shadow 
cat: /etc/shadow: Permission denied# denied normally 
[wang@vdevops ~]$ sudo /usr/bin/cat /etc/shadow 
[sudo] password for cent:# own password 
daemon:*:16231:0:99999:7::: 
adm:*:16231:0:99999:7::: 
lp:*:16231:0:99999:7::: 
... 
... 
# 輸入wang的密碼可以看到執(zhí)行結(jié)果

【2】設置用戶不能執(zhí)行危險命令

[root@vdevops ~]# visudo 
# 49行: 定義別名SHUTDOWN 
Cmnd_Alias SHUTDOWN = /sbin/halt, /sbin/shutdown, /sbin/poweroff, /sbin/reboot, /sbin/init 
# 設置用戶wang不能執(zhí)行別名SHUTDOWN對應的命令 
wang ALL=(ALL) ALL, !SHUTDOWN 
# 確保用戶為'wang' 
[wang@vdevops ~]$ sudo /sbin/shutdown -r now 
Sorry, user cent is not allowed to execute '/sbin/shutdown -r now' as root on vdevops.com. # denied normally

【3】創(chuàng)建一個特殊的組，組用戶可以執(zhí)行部分root命令

[root@vdevops ~]# visudo 
# 51行: 為管理用戶的幾個命令設置別名為USERMGR 
Cmnd_Alias USERMGR = /usr/sbin/useradd, /usr/sbin/userdel, /usr/sbin/usermod, /usr/bin/passwd 
# 最后一行添加 
%usermgr ALL=(ALL) USERMGR 
[root@vdevops ~]# groupadd usermgr 
[root@vdevops ~]# usermod -G usermgr wang 
# 確保用戶為wang 
[wang@vdevops ~]$ sudo /usr/sbin/useradd testuser 
#輸入用戶wang的密碼，查看創(chuàng)建結(jié)果，顯示成功 
[wang@vdevops ~]$ sudo /usr/bin/passwd testuser 
Changing password for user testuser. 
New UNIX password: 
Retype new UNIX password: 
passwd: all authentication tokens updated successfully.

【4】設置sudo日志

sudo的日志保存在/ var / log / secure中，但它中有很多種類的日志。如果你想保持只有sudo的日志在一個文件，設置如下：

[root@vdevops ~]# visudo 
# 最后一行添加 
Defaults syslog=local1 
[root@vdevops ~]# vi /etc/rsyslog.conf 
# 在54行修改，添加<span style="color:#FF6666;">local1.none</span> 
*.info;mail.none;authpriv.none;cron.none;<span style="color:#FF6666;">local1.none</span> 
/var/log/messages 
# 添加下面一行內(nèi)容 
local1.* /var/log/sudo.log 
[root@vdevops ~]# systemctl restart rsyslog #重啟rsyslog服務
