服务器环境配置nginx / php / php-fpm（一）

登陆，升级应用，查询和关闭selinux

yum update

getenforce

setenforce 0

vi /etc/selinux

添加非root用户

adduser deploy

passwd deploy

usermod -a -G wheel deploy
vi /etc/sudoers
%wheel ALL=(ALL) ALL

ssh配置

ssh deploy@123.456.78.90

ssh-keygen

mkdir ~/.ssh

scp ~/.ssh/id_rsa.pub deploy@123.456.78.90:

touch ~/.ssh/authorized_keys

cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

chown -R deploy:deploy ~/.ssh

chmod 700 ~/.ssh

chmod 600 ~/.ssh/authorized_keys

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
```

PHP、PHP-FPM 安装

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;

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

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

安装nginx

sudo yum install nginx;

sudo systemctl enable nginx.service;

sudo systemctl start nginx.service;

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

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;

    }

}

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

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。
多虚拟机参考http://www.androiddev.net/webserver-apache-to-nginx/

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;
