前言
本篇博客为使用dockerfile搭建lnmp并部署workpress
1. 安装docker
#关闭防火墙 systemctl disable --now firewalld setenforce 0 #安装docker并启动 yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo yum install -y docker-ce systemctl enable --now docker #修改网络转发功能（如果不修改，可能造成容器连不上外网，没办法下载环境） vim /etc/sysctl.conf net.ipv4.ip_forward=1 sysctl -p #注：若是后面在线源下载还是报错，则考虑清除/重新加载在线源，或者更新在线源 #从官网获取centos:7的镜像源 docker pull centos:7
2. 创建nginx容器
mkdir -p /data/nginx cd /data/nginx #获取nginx-1.12.0.tar.gz wordpress-4.9.4-zh_CN.tar.gz源码包 #编写Dockerfile配置文件（尽可能把命令放在一行，减少镜像层数，缩小镜像内存） vim Dockerfile FROM centos:7 MAINTAINER this is nginx image <lnmp> RUN yum install -y pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin nginx ADD nginx-1.12.0.tar.gz /usr/local/src/ WORKDIR /usr/local/src/nginx-1.12.0 RUN ./configure \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_stub_status_module;make -j 2 && make install ENV PATH /usr/local/nginx/sbin:$PATH ADD nginx.conf /usr/local/nginx/conf/ ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html RUN chmod 777 -R /usr/local/nginx/html/ EXPOSE 80 VOLUME [ "/usr/local/nginx/html/" ] CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ] #创建nginx配置文件 vim nginx.conf worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; charset utf-8; location / { root html; index index.html index.php; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { root html; fastcgi_pass 172.13.0.30:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; include fastcgi_params; } } } #创建nginx镜像（注意最后有个点，不可省略） docker build -t nginx:lnmp . docker images #通过镜像为nginx创建docker1容器，并制定网段为172.13.0.0/16 docker network create --subnet=172.13.0.0/16 --opt "com.docker.network.bridge.name"="docker1" lnmp #查看现有的容器网络模式 docker network ls #启动nginx容器并且为容器指定IP地址 docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net lnmp --ip 172.13.0.10 nginx:lnmp #验证nginx容器是否搭建成功 curl 192.168.109.133:80
3. 创建mysql容器
#创建mysql容器 mkdir -p /data/mysql #下载mysql源码包，wget，直接拖入都可 #编写Dockerfile配置文件 vim Dockerfile FROM centos:7 MAINTAINER this is mysql image <lnmp> RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make;useradd -M -s /sbin/nologin mysql ADD mysql-boost-5.7.20.tar.gz /usr/local/src/ WORKDIR /usr/local/src/mysql-5.7.20/ RUN cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ -DSYSCONFDIR=/etc \ -DSYSTEMD_PID_DIR=/usr/local/mysql \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_EXTRA_CHARSETS=all \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DWITH_BOOST=boost \ -DWITH_SYSTEMD=1;make -j 2;make install ADD my.cnf /etc/my.cnf EXPOSE 3306 RUN chown -R mysql:mysql /usr/local/mysql/;chown mysql:mysql /etc/my.cnf WORKDIR /usr/local/mysql/bin/ RUN ./mysqld \ --initialize-insecure \ --user=mysql \ --basedir=/usr/local/mysql \ --datadir=/usr/local/mysql/data;cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/;systemctl enable mysqld ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH VOLUME [ "/usr/local/mysql" ] CMD ["/usr/sbin/init"] #编写mysql配置文件 vim my.cnf [client] port = 3306 socket=/usr/local/mysql/mysql.sock [mysqld] user = mysql basedir=/usr/local/mysql datadir=/usr/local/mysql/data port = 3306 character-set-server=utf8 pid-file = /usr/local/mysql/mysqld.pid socket=/usr/local/mysql/mysql.sock bind-address = 0.0.0.0 skip-name-resolve max_connections=2048 default-storage-engine=INNODB max_allowed_packet=16M server-id = 1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES #生成mysql镜像文件并启动镜像容器（需要在对应目录中完成） docker build -t mysql:lnmp . docker run --name=mysql -d --privileged --device-write-bps /dev/sda:10M -v /usr/local/mysql --net lnmp --ip 172.13.0.20 mysql:lnmp
4. 搭建php容器

进入mysql容器进行授权
mysql -u root -p create database wordpress; grant all privileges on wordpress.* to 'wordpress'@'%' identified by 'abc123'; grant all privileges on *.* to 'root'@'%' identified by 'abc123'; flush privileges;
