篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了服务器环境配置nginx / php / php-fpm相关的知识,希望对你有一定的参考价值。

  1. 登陆,升级应用,查询和关闭selinux
    yum update
    getenforce
    setenforce 0
    vi /etc/selinux

     

  2. 添加非root用户
    adduser deploy
    passwd deploy
    usermod -a -G wheel deploy
    vi /etc/sudoers
    %wheel ALL=(ALL) ALL

     

  3. ssh配置
    技术分享
    ssh [email protected]
    ssh-keygen
    mkdir ~/.ssh
    scp ~/.ssh/id_rsa.pub [email protected]:
    touch ~/.ssh/authorized_keys
    cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
    chown -R deploy:deploy ~/.ssh
    chmod 700 ~/.ssh
    chmod 600 ~/.ssh/authorized_keys

  4. 禁止密码与root登陆,先确定sudo权限,打开 /etc/ssh/sshd_config,修改 PasswordAuthentication 的值为 no,取消注释。修改PermitRootLogin同上。重启SSHD。
    service sshd restart

     

  5. php、PHP-FPM 安装
    技术分享
    sudo rpm -Uvh  http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm;  
    //32位地址 http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
    sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm;

    sudo yum -y --enablerepo=epel,remi,remi-php56 install php-fpm php-cli php-gd php-mbstring php-mcrypt php-mysqlnd php-opcache php-pdo php-devel;

  6. PHP-FPM配置
    sudo vi /etc/php-fpm.conf
    //修改以下两处,1分钟内子进程失败达到10个就优雅重启
    emergency_restart_threshold = 10
    emergency_restart_interval = 1m

    在配置文件中有 include=/etc/php-fpm.d/*.conf   , 表示池定义 pool definition 在php-fpm.d目录下

    技术分享
    vi /etc/php-fpm.d/www.conf
    //修改用户,尽量每个网站一个用户
    user = deploy
    group = deploy
    //与nginx请求处理的端口
    listen = 127.0.0.1:9000
    //服务器内存除以进程占用内存
    pm.max_children = 50
    //开启服务时自动开启的准备进程数
    pm.start_servers = 3
    //每个池的最大进程数
    pm.max_requests = 1000
    //慢日志
    slowlog = /path/to/slowlog.log
    request_slowlog_timeout = 5s
    //最后重启服务
    sudo service php-fpm restart
    chkconfig php-fpm on

  7. 安装nginx
    sudo yum install nginx;
    sudo systemctl enable nginx.service;
    sudo systemctl start nginx.service;

     

  8. 建立网站目录与日志目录
    mkdir -p /home/deploy/apps/example.com/current/public
    mkdir -p /home/deploy/apps/logs
    chmod -R +rx /home/deploy

    建立 /etc/nginx/conf.d/example.conf

  9. 技术分享
    server 
    {
        listen 80;
        server_name example.com;
        index index.php;
        client_max_body_size 50M;
        error_log /home/deploy/apps/logs/example.error.log;
        access_log /home/deploy/apps/logs/example.access.log;
        root /home/deploy/apps/example.com/current/public;
        location / 
        {
            try_files $uri $uri/ /index.php$is_args$args;
        }
        location ~ \.php {
            try_files $uri=404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
            fastcgi_index index.php;
            fastcgi_pass 127.0.0.1:9000;
        }
    }

  10. 重启
    sudo systemctl restart nginx.service
    sudo chkconfig nginx on //如果权限失败了, 以root权限启动 sudo /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

     

  11. 检查防火墙,检查端口,检查selinux /getenforce ,最后可以编辑一个phpinfo页面放在网站根目录,在主机设置好hosts映射到虚拟机,终于可以在主机浏览器中输入虚拟机地址,见到php页面了。
  12. 多虚拟机参考http://www.androiddev.net/webserver-apache-to-nginx/
  13. 配置参考  http://huoding.com/2013/10/23/290

    server {
        listen 80;
        server_name foo.com;
    
        root /path;
        index index.html index.htm index.php;
    
        location / {
            try_files $uri $uri/ /index.php$is_args$args;
        }
    
        location ~ \.php$ {
            try_files $uri =404;
    
            include fastcgi.conf;
            fastcgi_pass 127.0.0.1:9000;
        }
    }

    fastcgi_pass unix:/dev/shm/php-fpm.sock;
