Linux - 安装
Linux - 安装注意事项:
修改网卡名: 在安装界面设置 注意不是换行!是空格!
net.ifnames=0 biosdevname=0

进行网卡配置:
修改localhost,自动链接网络
关闭SELinux:
修改配置文件:需要重启服务器 sed -i 's$=enforcing$=disbale$g' /etc/selinux/config 修改临时关闭: setenforce 查看状态: getenforce
修改网卡配置

Linux - 常用命令
cat:
cat -n cs.txt # 控制台显示行号
sed:
只查看ett.txt文件(共100行)内第20到第30行的内容 seq 40 > /oldboy/ett.txt cat /oldboy/ett.txt [root@oldboyedu-s8 oldboy]# #sed默认输出文件的每一行 [root@oldboyedu-s8 oldboy]# sed -n '20p' ett.txt 20 [root@oldboyedu-s8 oldboy]# #-n 取消默认输出 [root@oldboyedu-s8 oldboy]# 取20到 30行 [root@oldboyedu-s8 oldboy]# sed -n '20,30p' ett.txt
tar
创建压缩包: tar z # 通过gzip 软件进行压缩 tar c # create 归档 tar f # file 指定压缩包 查看压缩包内容: tar tf # 查看压缩包内容 解压缩: tar zxvf # 解压缩 v:显示解压过程
Linux - RPM包
""" 安装: rpm -ivh bask-completion.rpm """
Linux - 防火墙
在CentOS7开始,默认是没有iptables的,而是使用了firewall防火墙.
[root@ClementLinux ~]# systemctl stop firewalld.service # 停止服务
[root@ClementLinux ~]# systemctl status firewalld.service # 查看服务状态
[root@ClementLinux ~]# systemctl disable firewalld.service # 禁止开机自启
[root@ClementLinux ~]# systemctl is-active firewalld.service # 是否处于活动状态
[root@ClementLinux ~]# systemctl is-enabled firewalld.service # 是否开机自启
Linux - 定时任务
-e:编辑该用户的计时器设置; -l:列出该用户的计时器设置; -r:删除该用户的计时器设置; -u<用户名称>:指定要设定计时器的用户名称。 crontab文件:指定包含待执行任务的crontab文件。 文件路径:/etc/crontab
符号:
* : 每; 分/时/日/月/周
/ : 间隔; 分/时/日/月/周
Linux - 时间同步
pass
Linux - 那些有意思的RPM
yum install sl cowsay -y
Linux - Nginx安装
编译三部曲:
./configure \ --prefix=/application/nginx-1.12.2 \ --with-http_stub_status_module \ --with-http_ssl_module
会出先错误
./configure: error: the HTTP rewrite module requires the PCRE library. You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre=<path> option.
提示:缺少PCRE library
解决办法:
yum install -y pcre-devel
继续./configure
提示缺少OpenSSL
./configure: error: SSL modules require the OpenSSL library. You can either do not enable the modules, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-openssl=<path> option.
解决办法:
yum install -y openssl-devel
提示成功!
