2020-01-01 解决docker使用的问题

1、启动nginx/usr/local/nginx/sbin/nginx -s reload 重新读取配置文件出错

使用默认的nginx.conf启动项目

[root@58a68b2af36c sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@58a68b2af36c sbin]# ./nginx -s reload 
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"
[root@localhost nginx]# cd logs
[root@localhost logs]# ls
access.log  error.log  nginx-access.log  nginx_error.log
# 果然没有/usr/local/nginx/logs/nginx.pid 文件
[root@58a68b2af36c sbin]# ./nginx -c /usr/local/nginx/conf/nginx.conf

2、解决docker交互式运行容器不能使用 ll 命令

[root@58a68b2af36c php]# echo  "alias ll='ls $LS_OPTIONS -l'" >> ~/.bashrc && source ~/.bashrc
[root@58a68b2af36c php]# vim ~/.bashrc

3、解决php-fpm启动报错

[root@58a68b2af36c sbin]# ./php-fpm 
[01-Jan-2020 20:48:48] ERROR: failed to open configuration file '/usr/local/php/etc/php-fpm.conf': No such file or directory (2)
[01-Jan-2020 20:48:48] ERROR: failed to load configuration file '/usr/local/php/etc/php-fpm.conf'
[01-Jan-2020 20:48:48] ERROR: FPM initialization failed

解决方法：

[root@58a68b2af36c sbin]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf  
[root@58a68b2af36c sbin]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
[root@58a68b2af36c sbin]# ./php-fpm 

4、解决nginx+php下访问不了php文件

2020/01/01 20:55:08 [error] 43#0: *4 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 223.74.101.69, server: localhost, request: "GET /i.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "121.40.191.171:8080"

• 配置问题 $document_root

        location ~ \.php$ {
            root           /usr/local/nginx/html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

• 文件访问权限
  ls

使用Dockerfile构建nginx+php环境

# 配置PHP文件
RUN cp /soft/php-7.2.25/php.ini-production /usr/local/php/lib/php.ini && \
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf && \
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/wwww.conf &&\
echo 'export PHP_HOME=/usr/local/php' >> /etc/profile && echo 'export PATH=$PATH:$PHP_HOME/bin' >> /etc/profile && \
source /etc/profile 

# 解决交互式启动docker无法使用ll命令
RUN echo  "alias ll='ls $LS_OPTIONS -l'" >> ~/.bashrc && source ~/.bashrc

# mysql 有点不成功，不知道docker内部怎么启动mysql，也用不了service命令

# COPY ./mysql-community-server-5.7.28-1.el7.x86_64.rpm /soft/
# COPY ./mysql-community-client-5.7.28-1.el7.x86_64.rpm /soft/

# RUN cd /soft && rpm -ivh  mysql-community-server-5.7.28-1.el7.x86_64.rpm --force --nodeps && \
# rpm -ivh mysql-community-client-5.7.28-1.el7.x86_64.rpm --force --nodeps

#EXPOSE 映射端口
EXPOSE 80 9000 

#CMD 运行以下命令
CMD /bin/bash

运行之后修改nginx配置文件并启动、php启动，测试就可以。
