Python写一个CentOS系统上安装LNMP的运维小脚本

介绍

以下是一个简单的Python脚本，用于在CentOS系统上使用Yum自动安装并配置LNMP（Linux、Nginx、MySQL、PHP）环境。

脚本实现

import os
# Step 1: Install EPEL repositoryos.system('yum install -y epel-release')
# Step 2: Install Nginxos.system('yum install -y nginx')
# Step 3: Start Nginxos.system('systemctl start nginx')os.system('systemctl enable nginx')
# Step 4: Install MySQL (MariaDB)os.system('yum install -y mariadb-server mariadb')os.system('systemctl start mariadb')os.system('systemctl enable mariadb')
# Step 5: Install PHPos.system('yum install -y php php-mysql php-fpm')
# Step 6: Configure PHP-FPMos.system("sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/g' /etc/php.ini")os.system("sed -i 's/listen = 127.0.0.1:9000/listen = /var/run/php-fpm/php-fpm.sock/g' /etc/php-fpm.d/www.conf")os.system("sed -i 's/;listen.owner = nobody/listen.owner = nginx/g' /etc/php-fpm.d/www.conf")os.system("sed -i 's/;listen.group = nobody/listen.group = nginx/g' /etc/php-fpm.d/www.conf")os.system("sed -i 's/user = apache/user = nginx/g' /etc/php-fpm.d/www.conf")os.system("sed -i 's/group = apache/group = nginx/g' /etc/php-fpm.d/www.conf")
# Step 7: Start PHP-FPMos.system('systemctl start php-fpm')os.system('systemctl enable php-fpm')
# Step 8: Configure Nginx to use PHP Processornginx_conf = """server {    listen       80;    server_name  localhost;
    location / {        root   /usr/share/nginx/html;        index  index.php index.html index.htm;    }
    error_page   500 502 503 504  /50x.html;    location = /50x.html {        root   /usr/share/nginx/html;    }
    location ~ \.php$ {        root           /usr/share/nginx/html;        fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;        include        fastcgi_params;    }}"""with open('/etc/nginx/conf.d/default.conf', 'w') as f:    f.write(nginx_conf)
# Step 9: Restart Nginxos.system('systemctl restart nginx')

    请注意，这个脚本需要在有root权限的系统上运行。

请注意，这个脚本只完成了基本的安装和配置工作，你可能需要根据自己的需求对其进行进一步的修改和配置。

注意：在生产环境中，你还需要考虑如何设置防火墙规则，如何配置MySQL的安全选项，如何处理PHP的错误报告，如何限制PHP的资源使用等等。
