php ready to handle connections,php-fpm 问题，就解

如果你遇到 "php ready to handle connections" 或者 "php-fpm 问题"，可能是由于以下原因：

1. PHP-FPM 进程没有启动
2. PHP-FPM 配置文件中的错误
3. PHP-FPM 进程的权限问题
4. 系统资源不足

解决方法：

1. 确保 PHP-FPM 进程已经启动。可以通过以下命令检查进程是否已经启动：

   ps aux | grep php-fpm

2. 检查 PHP-FPM 配置文件中是否有语法错误。可以使用以下命令检查：

   php-fpm -t

3. 检查 PHP-FPM 进程的权限问题。确保 PHP-FPM 进程有足够的权限来访问所需的目录和文件。

4. 如果系统资源不足，可以尝试增加服务器的内存和 CPU 配置。

希望这些方法可以帮助你解决问题。

详细描述一下 ansible-varnish-nginx-php-fpm-ftp-mysql的部署流程

非常感谢您的提问，我将为您详细描述 ansible-varnish-nginx-php-fpm-ftp-mysql 的部署流程。

前置条件：

- 安装 Ansible 工具
- 所有主机都配置好 SSH 免密登录
- 所有主机都已安装 Python 2.x 或 Python 3.x

步骤：

1. 编写 Ansible 配置文件

创建一个名为 inventory 的文件，并在其中定义要部署的主机列表和相关变量：

[web]
webserver ansible_host=192.168.1.10 ansible_user=<your_user> ansible_ssh_private_key_file=<your_ssh_key>
dbserver ansible_host=192.168.1.11 ansible_user=<your_user> ansible_ssh_private_key_file=<your_ssh_key>

[web:vars]
nginx_version=1.14.1
php_version=7.2
mysql_version=5.7

2. 编写 Ansible Playbook

创建一个名为 playbook.yml 的文件，并编写 Ansible Playbook。以下是一个示例 Playbook，包含安装和配置 varnish、nginx、PHP-FPM、FTP 和 MySQL。

- hosts: web
  become: true
  vars_files:
    - vars.yml
  tasks:
    # 安装 Varnish
    - name: Install Varnish
      yum:
        name: varnish
        state: present

    # 安装 Nginx
    - name: Install Nginx
      yum:
        name: nginx
        state: present
      notify:
        - Restart Nginx

    # 配置 Nginx
    - name: Configure Nginx
      template:
        src: templates/nginx.conf.j2
        dest: /etc/nginx/nginx.conf
      notify:
        - Restart Nginx

    # 安装 PHP-FPM
    - name: Install PHP-FPM
      yum:
        name: php-fpm
        state: present
      notify:
        - Restart PHP-FPM

    # 配置 PHP-FPM
    - name: Configure PHP-FPM
      template:
        src: templates/php-fpm.conf.j2
        dest: /etc/php-fpm.conf
      notify:
        - Restart PHP-FPM

    # 安装 FTP
    - name: Install FTP
      yum:
        name: vsftpd
        state: present
      notify:
        - Restart FTP

    # 配置 FTP
    - name: Configure FTP
      template:
        src: templates/vsftpd.conf.j2
        dest: /etc/vsftpd/vsftpd.conf
      notify:
        - Restart FTP

    # 安装 MySQL
    - name: Install MySQL
      yum:
        name: mysql-community-server
        state: present
      notify:
        - Start MySQL

    # 配置 MySQL
    - name: Configure MySQL
      template:
        src: templates/my.cnf.j2
        dest: /etc/my.cnf
      notify:
        - Start MySQL

  handlers:
    # 重启 Nginx
    - name: Restart Nginx
      systemd:
        name: nginx
        state: restarted

    # 重启 PHP-FPM
    - name: Restart PHP-FPM
      systemd:
        name: php-fpm
        state: restarted

    # 重启 FTP
    - name: Restart FTP
      systemd:
        name: vsftpd
        state: restarted

    # 启动 MySQL
    - name: Start MySQL
      systemd:
        name: mysqld
        state: started

3. 准备模板文件

创建模板文件，用于生成配置文件。以下是模板文件示例代码：

nginx.conf.j2

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

events {
    worker_connections 1024;
    use epoll;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile on;

    keepalive_timeout 65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  /var/log/nginx/host.access.log  main;

        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$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

    }

    include /etc/nginx/conf.d/*.conf;

}

php-fpm.conf.j2

[global]
pid = /var/run/php-fpm/php-fpm.pid
error_log = /var/log/php-fpm/error.log
emergency_restart_threshold = 5
emergency_restart_interval = 1m
process_control_timeout = 10
daemonize = no

[www]
user = nginx
group = nginx
listen = 127.0.0.1:9000
listen.owner = nginx
listen.group = nginx
listen.mode = 0660
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 500

vsftpd.conf.j2

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
xferlog_file=/var/log/xferlog
xferlog_std_format=YES
chroot_local_user=YES
allow_writeable_chroot=YES
local_root=/var/www/html/
listen=YES
listen_ipv6=NO
pam_service_name=vsftpd
userlist_enable=YES

my.cnf.j2

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
symbolic-links=0
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 256M
table_open_cache = 16384
sort_buffer_size = 512K
net_buffer_length = 16K
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size = 16M
query_cache_limit = 1M
log-bin=mysql-bin
binlog_format=ROW
server-id=1
innodb_buffer_pool_size = 256M
innodb_log_file_size = 64M
default-storage-engine=innodb
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci

[client]
socket=/var/lib/mysql/mysql.sock

[mysql]
socket=/var/lib/mysql/mysql.sock

4. 运行 Ansible Playbook

运行以下命令来运行 Ansible Playbook：

$ ansible-playbook -i inventory playbook.yml

此命令将在指定主机上按顺序执行 Playbook 中的每个任务，安装和配置所有必需的软件包和服务，最终实现 ansible-varnish-nginx-php-fpm-ftp-mysql 的部署。

redis安装Ready to accept connections

要使Redis安装完成并准备好接受连接，你需要进行以下几个步骤：

首先，在终端中输入以下命令来启用Redis服务：
[root@localhost bin]# systemctl enable redis.service

接下来，使用以下命令将Redis安装到指定的路径：
[root@localhost redis-5.0.3]# make install PREFIX=/usr/local/redis

最后，使用以下命令来启动Redis服务：
[root@localhost bin]# systemctl start redis.service

完成这些步骤后，Redis将会准备好接受连接，并可以开始提供服务了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
