Linux实验4（FastDFS、nginx、docker）
Linux实验4
- FastDFS集群
- 复制一个虚拟机
- 1.修改一下路径
- 2.没有/etc/fdfs/mod_fastdfs.conf文件
- 3.fdfs_storaged /etc/fdfs/storage.conf start启动失败
- 4.没有/root/fdfs/logs/trackerd.log文件
- 5.fdfs_test
- 6.安装nginx
- 7.在浏览器上访问，长时间没有响应
- docker搭建LNMP-PHP
- 1.docker启动失败
- 2.之前配置的nginx浏览器访问不了，但是却可以curl
- 参考以下博客安装FastDFS集群.至少两台机器构成集群.并测试上传和访问成功.

后记：这个博文有点糟糕，推荐这个博文- 参考以下博客利用docker搭建LNMP-PHP运行环境
https://blog.csdn.net/UserPHP/article/details/100728267
所用环境:
VMWare12.5.7
CentOS-7-x86_64-Minimal-1908
FastDFS集群
复制一个虚拟机
- Linux先关机
- 在VMWare上，文件->导出为OVA，再导入，即可
1.修改一下路径
~/miao/fdfs-package
/root/miao/fdfs
2.没有/etc/fdfs/mod_fastdfs.conf文件
//在这里，复制一份
/root/miao/fdfs-package/fastdfs-nginx-module-1.20/src
3.fdfs_storaged /etc/fdfs/storage.conf start启动失败
process fdfs_trackerd already running, pid: 3159
4.没有/root/fdfs/logs/trackerd.log文件
tail -n10 ~/miao/fdfs/logs/trackerd.log
5.fdfs_test
新建~/miao/test_images/，rz一个图片
fdfs_test /etc/fdfs/client.conf upload ~/miao/test_images/卡布奇诺.jpg
6.安装nginx
下载安装包，./configure安装
//custom_configure
//去掉第2，3行
//最后一行修改
--add-module=/root/miao/fdfs-package/fastdfs-nginx-module-1.20/src/
//环境依赖
yum -y install gcc
yum -y install gcc-c++
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel
//若出现编译错误，还需要
yum -y install libxml2 libxml2-dev
yum -y install libxslt-devel
yum -y install gd-devel
yum -y install GeoIP GeoIP-devel GeoIP-data
//编译的时候出现错误
# 修改fastdfs-nginx-module的src/config文件
$ cd /root/miao/fdfs-package/fastdfs-nginx-module-1.20/src
$ vim config
# 修改一下两项：
ngx_module_incs="/usr/include/fastdfs /usr/include/fastcommon/"
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"
//如下安装成功
#可以记录一下

nginx path prefix: "/usr/share/nginx"
nginx binary file: "/usr/share/nginx/sbin/nginx"
nginx modules path: "/usr/share/nginx/modules"
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
nginx pid file: "/run/nginx.pid"
nginx error log file: "/var/log/nginx/error.log"
nginx http access log file: "/var/log/nginx/access.log"

nginx http proxy temporary files: "/var/lib/nginx/proxy"
nginx http fastcgi temporary files: "/var/lib/nginx/fastcgi"
nginx http uwsgi temporary files: "/var/lib/nginx/uwsgi"
nginx http scgi temporary files: "/var/lib/nginx/scgi"
配置nginx
文件/etc/nginx/nginx.conf
location / {
#root html;
#index index.html index.htm;
root /root/miao/fdfs/data;
ngx_fastdfs_module;
}
开启nginx
//新建目录
mkdir /var/lib/nginx/body
nginx
关闭防火墙(添加信任)
//打开文件
vim /etc/sysconfig/iptables
//添加
-A INPUT -p tcp -m state --state NEW -m tcp --dport 9270 -j ACCEPT
可以利用curl -i 192.168.17.220:9270测试（建议端口号同一改成9270）
7.在浏览器上访问，长时间没有响应
推荐查看一下nginx的日志文件,根据error.log日志debug
tail -f /var/log/nginx/access.log
tail -f /var/log/nginx/error.log
//查看进程
netstat -tupln
//kill掉ngnix
//重新启动nginx
nginx
日志报错
[2015-11-10 21:04:04] ERROR - file: …/common/fdfs_global.c, line: 52,the format of filename “group1/M00/00/00/xxxxxxxxxxx” is invalid
//解决办法
vim /etc/fdfs/mod_fastdfs.conf
url_have_group_name = true
ERROR - file: /root/miao/fdfs-package/fastdfs-nginx-module-1.20/src//common.c, line:1100, stat file:/root/miao/fdfs/storage/data/00/00/wKgR3F6dvzGAAAi2AADDeM3aQtc887_big.jpg fail, errno: 13, error info: Permission denied
vim /etc/nginx/nginx.conf
#在第一行加上
user root;
如果在浏览器上访问，可以看见图片就完成了
docker搭建LNMP-PHP
1.docker启动失败
Process: 16369 ExecStart=/usr/bin/dockerd -H fd://
–containerd=/run/containerd/containerd.sock (code=exited, status=1/FAILURE) Main PID: 16369 (code=exited, status=1/FAILURE)4月 21 01:26:58 localhost.localdomain systemd[1]: docker.service: main

可能原因和解决办法
- /etc/docker/daemon.json文件错误
- 升级内核
yum update -y kernel
reboot
之后按照步骤来，就完成了
2.之前配置的nginx浏览器访问不了，但是却可以curl
#关闭firewalld
service firewalld stop
#永久关闭
systemctl disable firewalld
常用命令
docker ps -a # 查看容器
docker ps #查看正在运行的容器
docker stop mynginx # 停止正在运行的容器
docker start mynginx # 启动一个已经停止的容器
docker restart mynginx # 重启一个容器
docker rm mynginx # 删除容器
docker logs 容器名
docker run xxxxxxx
docker run命令 宿主机内容:容器内容
-network 指定网络
-name 指定容器名字
-p端口映射
-v文件/目录映射
