使用docker-compose部署LNMP环境

1、创建相关compose存放目录

< 5 docker-test - [root]: > mkdir -p /apps/compose_lnmp/nginx
< 5 docker-test - [root]: >  cd !$
< 5  docker-test - [root]: /apps/compose_lnmp/nginx >

2、下载nginx软件包，创建dockerfile

< 6  docker-test - [root]: /apps/compose_lnmp/nginx > # wget http://nginx.org/download/nginx-1.14.2.tar.gz

< 7  docker-test - [root]: /apps/compose_lnmp/nginx > # vim Dockerfile

FROM centos:7
MAINTAINER gujiwork
RUN yum install -y gcc gcc-c++ make openssl-devel pcre-devel
ADD nginx-1.14.2.tar.gz /tmp
RUN cd /tmp/nginx-1.14.2 && ./configure --prefix=/usr/local/nginx && ma
5b4
ke -j 4 && make install
COPY nginx.conf  /usr/local/nginx/conf

EXPOSE 80
WORKDIR /usr/local/nginx
CMD ["./sbin/nginx", "-g", "daemon off;"]

3、这里面用到了nginx.conf，放到compose_lnmp/nginx目录下，将 fastcgi_pass 127.0.0.1:9000改成php容器名， fastcgi_pass php-cgi:9000;

#user  nginx;
worker_processes  2;
worker_cpu_affinity 0101 1010;

#error_log  logs/error.log;
error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
worker_connections  10240;
}

http {
include       mime.types;
default_type  application/octet-stream;
server_tokens off;

#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  logs/access.log  main;

sendfile        on;
tcp_nopush on;
tcp_nodelay on;
server_names_hash_bucket_size 128;
server_names_hash_max_size 512;
client_header_timeout 15s;
client_body_timeout 15s;
send_timeout 60s;

#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
listen       80;
server_name  localhost;

#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {
root   html;
index
b68
index.html index.htm;
}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
#    proxy_pass   http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root           html;
fastcgi_pass   php-cgi:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
include        fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
#    deny  all;
#}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#    listen       8000;
#    listen       somename:8080;
#    server_name  somename  alias  another.alias;

#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}

# HTTPS server
#
#server {
#    listen       443 ssl;
#    server_name  localhost;

#    ssl_certificate      cert.pem;
#    ssl_certificate_key  cert.key;

#    ssl_session_cache    shared:SSL:1m;
#    ssl_session_timeout  5m;

#    ssl_ciphers  HIGH:!aNULL:!MD5;
#    ssl_prefer_server_ciphers  on;

#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}
include vhost/*.conf;
}

4、创建mysql目录，数据和配置文件做持久化，这里我们使用mysql官方镜像，因此不需要写dockerfile

< 39  docker-test - [root]: /apps/compose_lnmp > # tree  mysql/
mysql/
|-- conf
|   `-- my.cnf
`-- data

< 40  docker-test - [root]: /apps/compose_lnmp > # cat mysql/conf/my.cnf
[mysqld]
user=mysql
port=3306
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.socket
pid-file=/var/run/mysql/mysql.pid
log_error=/var/log/mysql/error.log
character_set_server = utf8
max_connections=3600

5、创建php目录及dockerfile，php.ini主要修改了时区为shanghai

< 49  docker-test - [root]: /apps/compose_lnmp > # tree  php/
php/
|-- Dockfile
|-- php-5.6.31.tar.gz
`-- php.ini

< 50  docker-test - [root]: /apps/compose_lnmp > # cat php/Dockfile
FROM centos:7
MAINTAINER gujiwork
RUN yum install -y gcc gcc-c++ gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel make
ADD php-5.6.31.tar.gz /tmp/
RUN cd /tmp/php-5.6.31 && \
./configure --p
5ac
refix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--with-mysql --with-mysqli \
--with-openssl --with-zlib --with-curl --with-gd \
--with-jpeg-dir --with-png-dir --with-iconv \
--enable-fpm --enable-zip --enable-mbstring && \
make -j 4 && make install && \
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf && \
sed -i "s/127.0.0.1/0.0.0.0/" /usr/local/php/etc/php-fpm.conf && \
cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm && \
chmod +x /etc/init.d/php-fpm
COPY php.ini /usr/local/php/etc

EXPOSE 9000
CMD /etc/init.d/php-fpm start && tail -F /var/log/messages

6、创建docker-compose维护文件

< 53  docker-test - [root]: /apps/compose_lnmp > # cat docker-compose.yml
version: '3'
services:
nginx:
hostname: nginx
build:
context: ./nginx
dockerfile: Dockerfile
ports:
- 80:80
links:
- php:php-cgi
volumes:
- ./wwwroot:/usr/local/nginx/html

php:
hostname: php
build: ./php
links:
- mysql:mysql-db
volumes:
- ./wwwroot:/usr/local/nginx/html

mysql:
hostname: mysql
image: mysql:5.6
ports:
- 3306:3306
volumes:
- ./mysql/conf:/etc/mysql/conf.d
- ./mysql/data:/var/lib/mysql
#command: --character-set-server=utf8
environment:
MYSQL_ROOT_
1c7c
PASSWORD: 123456
MYSQL_DATABASE: wordpress
MYSQL_USER: user
MYSQL_PASSWORD: user123

7、创建web挂载目录，整体目录结构如下

< 56  docker-test - [root]: /apps/compose_lnmp > # tree .
.
|-- docker-compose.yml
|-- mysql
|   |-- conf
|   |   `-- my.cnf
|   `-- data
|-- nginx
|   |-- Dockerfile
|   |-- nginx-1.14.2.tar.gz
|   `-- nginx.conf
|-- php
|   |-- Dockfile
|   |-- php-5.6.31.tar.gz
|   `-- php.ini
`-- wwwroot

6 directories, 8 files

8、执行build构建镜像

< 81  docker-test - [root]: /apps/compose_lnmp > # docker-compose  build

9、出现success表示构建成功

make[1]: Leaving directory `/tmp/nginx-1.14.2'

10、启动服务测试

< 82  docker-test - [root]: /apps/compose_lnmp > # docker-compose  up -d
