Linux中KVM桥接网卡br0

CentOS 6以上版本在使用KVM虚拟化的时，会需要配置到桥接网卡，下面简单的介绍一下桥接的方法：

1、查看网卡的现有状态：

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s25
UUID=f4656320-077f-4e68-ae2f-a697bddf2766
DEVICE=enp0s25
ONBOOT=yes

2、Copy一份网卡为br0

cp ifcfg-enp0s25 ifcfg-br0

3、修改 enp0s25：最后增加BRIDGE=br0，如果是静态地址，只需要修改 BOOTPROTO=static即可



TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s25
UUID=f4656320-077f-4e68-ae2f-a697bddf2766
DEVICE=enp0s25
ONBOOT=yes
BRIDGE=br0

4、修改br0，重点是TYPE和DEVICE，DHCP还是STATIC根据实际情况配置

TYPE=Bridge
BOOTPROTO=dhcp
DEVICE=br0
ONBOOT=yes

5、重启网卡服务，查看桥接情况

Windows下实现Nginx开机自启动
1.右击“新建”->点击“文本文档”->双击打开”文本文档”复制粘贴一下内容：
```

<service>
    <id>nginx</id>   
    <name>Nginx Service</name>   
    <description>High Performance Nginx Service</description>
    <env name="path" value="D:\Nginx-auto\nginx-1.14.0.57-A\"></env>
    <executable>nginx.exe</executable>
    <executable>nginx.exe -s stop</executable>
    <logpath>D:Nginx-auto\nginx-1.14.0.57-A\logs\</logpath>
    <log mode="roll-by-size">     
        <sizeThreshold>10240</sizeThreshold>     
        <keepFiles>8</keepFiles>   
    </log>
</service>
```
2.右击“新建”->点击“文本文档”->双击打开”文本文档”复制粘贴一下内容：
```
<configuration>  
    <startup>    
        <supportedRuntime version="v2.0.50727" />    
        <supportedRuntime version="v4.0" />  
    </startup>  
    <runtime>    
        <generatePublisherEvidence enabled="false"/>   
    </runtime>
</configuration>
```
Ctrl + s保存->右击“文本文档”->重命名” nginx-service.xml”

Ctrl + s保存->右击“文本文档”->重命名” nginx-service.exe.config”

3.下载“WinSW.NETCore.x64.exe”->重命名“nginx-service.exe”:

Win + R->cmd回车->nginx-service.exe install

注：执行完后即可在“服务”列表看到Nginx Service服务点击启动并设置自动即可。
（设置开机自启的同时reload将无法使用，只能执行ln-stop.bat关闭服务）

Nginx设置成开机自动启动服务

1、在/etc/init.d下创建文件nginx，文件的内容拷贝官网内容，主要修改下面两个参数的值

nginx=”/usr/sbin/nginx” #修改成nginx执行程序的路径。
NGINX_CONF_FILE=”/etc/nginx/nginx.conf” #修改成nginx.conf文件的路径。

样例如下：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid
 
# Source function library.
. /etc/rc.d/init.d/functions
 
# Source networking configuration.
. /etc/sysconfig/network
 
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
 
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
 
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
 
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
 
lockfile=/var/lock/subsys/nginx
 
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:.*--user=" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if [ -n "$user" ]; then
      if [ -z "`grep $user /etc/passwd`" ]; then

2、保存后设置文件的执行权限

chmod a+x /etc/init.d/nginx

3、将nginx服务加入chkconfig管理列表，加完这个之后，就可以使用service对nginx进行启动，重启等操作了。

chkconfig --add /etc/init.d/nginx
service nginx start
service nginx stop
service nginx restart
service nginx status

4、最后设置开机自动启动

chkconfig nginx on

运行python脚本后台执行

在Linux中，可以使用nohup将脚本放置后台运行，如下：

nohup python myscript.py params1 > nohup.out 2>&1 &

但直接使用上面代码，无法在程序运行过程中查看Python中的print “computing” 输出结果，比如在每次循环中使用print语句等。原因是python的输出有缓冲，导致nohup.out不能够马上看到输出。

解决方法：
使用-u参数，使得python不启用缓冲

修改命令如下：
nohup python -u myscript.py params1 > nohup.out 2>&1 &

pip安装requests时报https/tls/ssl错误

pip安装requests时报错，提示如下：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available
.",)) - skipping

经过多次测试，发现是url的来源的问题,换成了国内的pip源就可以正常安装了,我使用的是:

pip3 install requests -i http://pypi.douban.com/simple –trusted-host pypi.douban.com

还可以使用以下地址

1) http://mirrors.aliyun.com/pypi/simple/ 阿里云

2) https://pypi.mirrors.ustc.edu.cn/simple/  中国科技大学

3) http://pypi.douban.com/simple/  豆瓣

4) https://pypi.tuna.tsinghua.edu.cn/simple/ 清华大学

Linux升级openssl1.1.1l

1、下载openssl

wget https://www.openssl.org/source/openssl-1.1.1l.tar.gz

2、创建安装目录

mkdir -p usr/local/openssl

3、解压

tar -zxvf  openssl-1.1.1l.tar.gz

4、编译安装

cd openssl-1.1.1l
./config --prefix=/usr/local/openssl no-zlib #不需要zlib
make
make install

5、备份原配置

mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl/ /usr/include/openssl.bak

6、新版配置

ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/local/lib64/libssl.so
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl

7、修改系统配置，写入openssl库文件的搜索路径

echo "/usr/local/openssl/lib" >> /etc/ld.so.conf

8、使修改后的/etc/ld.so.conf生效

ldconfig -v

9、查看openssl版本

[root@test ~]#openssl version
OpenSSL 1.1.1l 24 Aug 2021
