docker consul+compose部署_综合

docker部署

1.安装依赖包

yum install -y yum-utils device-mapper-persistent-data lvm2

2.设置阿里云镜像源

cd /etc/yum.repos.d/
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3.安装docker-ce 社区版

yum install -y docker-ce

4.环境配置

systemctl stop firewalld
systemctl disable firewalldsetenforce 0vim /etc/selinux/config
SELINUX=disabled

5.设置开机自启并启动（此处为了让docker在/etc/docker/下生成daemon.json文件）

systemctl start docker
systemctl enable docker

6.修改配置文件：==》 registry-mirrors 为加速器

tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": ["https://jqqwsp8f.mirror.aliyuncs.com"]
}
EOF

7.修改完成后需要重启

systemctl daemon-reload
systemctl restart docker

8.网络优化，此处开启ipv4的转发功能

echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
sysctl -p
systemctl restart network
systemctl restart docker

consul部署

1.创建consul文件夹

mkdir /root/consul

2.拷贝

cp consul_0.9.2_linux_amd64.zip /root/consul
cd /root/consul

3.解压

上传consul软件包
unzip consul_0.9.2_linux_amd64.zip
4.将文件移动到/usr/bin
mv consul /usr/bin

5.执行命令，设置consul的server

consul agent \
-data-dir=/var/lib/consul-data \
-bind=192.168.218.214 \
-server \
-bootstrap \
-ui \
-client=0.0.0.0 \
-node=consul-server01 &> /var/log/consul.log &

6.验证集群信息

consul members  
或者
consul info | grep leader##通过httpd api 获取集群信息
curl 127.0.0.1:8500/v1/status/peers   //查看集群server成员
curl 127.0.0.1:8500/v1/status/leader //集群 Raf leader
curl 127.0.0.1:8500/v1/catalog/services //注册的所有服务
curl 127.0.0.1:8500/v1/catalog/nginx  //查看 nginx 服务信息

验证结果

consul服务器上部署nginx

1.安装依赖包

yum -y install gcc gCc-c++ pcre-devel zlib-devel make

2.创建用户组

useradd -M -s /sbin/nologin nginx

3.解压opt/中的nginx.tar

tar xzvf nginx -1.15.9.tar.gz

4.进入文件，并加载模块初始化

cd nginx-1.15.9/
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module

5.编译并安装

make && make install

6.路径优化

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
ls -l /usr/local/sbin/nginx

7.设置nginx的systemctl 的管理

vim /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile =/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

8.配置 nginx


vim /usr/local/nginx/conf/nginx.confhttp {
    include       mime.types;include  vhost/*.conf; //添加虚拟主机目录（consul动态生成的配置文件就会放在这里）default_type application/octet-stream;##创建虚拟主机目录 mkdir /usr/local/nginx/conf/vhost ##创建日志文件目录 mkdir /var/log/nginx

9.赋权

chmod +x /usr/lib/systemd/system/nginx.service
10.启动
systemctl start nginx
11.验证
netstat -antp | grep 80

web端部署docker-compose

1.//下载compose（上传docker_compose）

curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

2.拷贝到/usr/local/bin

cp -p docker-compose /usr/local/bin/
chmod +x /usr/local/bin/docker-compose

3.创建compose_nginx

mkdir /root/compose_nginx

4.修改配置文件

vim /root/compose_nginx/docker-compose.ymlversion: '3'
services:nginx:hostname: nginxbuild:context: ./nginxdockerfile: Dockerfileports:- 1216:80- 1217:443networks:- clustervolumes:- ./wwwroot:/usr/local/nginx/html
networks:cluster:

5.进入compose_nginx目录

cd /root/compose_nginx/
mkdir nginx
vim Dockerfile
FROM centos:7 as build 
ADD nginx-1.15.9.tar.gz /mnt 
WORKDIR /mnt/nginx-1.15.9
RUN yum install -y gcc pcre pcre-devel devel zlib-devel make &> /dev/null && \yum clean all &&\sed -i 's/CFLAGS="$CFLAGS -g"/#CFLAGS="$CFLAGS -g"/g' auto/cc/gcc && \./configure --prefix=/usr/local/nginx &> /dev/null && \make &>/dev/null && \make install &>/dev/null && \rm -rf /mnt/nginx-1.15.9 FROM centos:7 
EXPOSE 80
VOLUME ["/usr/local/nginx/html"]
COPY --from=build /usr/local/nginx /usr/local/nginx
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

6.创建镜像并启动

docker-compose -f docker-compose.yml up -d

设置容器服务自动加入consul

1.执行registrator命令

docker run -d \
--name=registrator \
--net=host \
-v /var/run/docker.sock:/tmp/docker.sock \
--restart=always \
gliderlabs/registrator:latest \
-ip=192.168.218.215 \
consul://192.168.218.214:8500

2.测试服务发现功能是否正常

docker run -itd -p:83:80 --name test-01 -h test01 nginx

3.验证 http 和 nginx 服务是否注册到 consul

浏览器输入 http://192.168.218.214:8500，“单击 NODES”，然后单击 “consurl-server01”，会出现 1 个服务.

在consul服务端配置并启动template

上传 consul-template_0.19.3_linux_amd64.zip 包到/root 目录下

cp consul-template_0.19.3_linux_amd64.zip /root/

3.解压包

unzip consul-template_0.19.3_linux_amd64.zip

4.将解压的文件夹移动到/usr/bin/

mv consul-template /usr/bin/

5.设置template nginx模板

upstream http_backend {
    {
    {
    range service "nginx"}}server {
    {
    .Address}}:{
    {
    .Port}};		#??此处引用的变量会指向后端的地址和端口（动态变化）{
    {
    end}}
}server {
    listen 83;server_name localhost 192.168.218.214;		#反向代理的IP地址access_log /var/log/nginx/kgc.cn-access.log;index index.html index.php;location / {
    proxy_set_header HOST $host;proxy_set_header X-Real-IP $remote_addr;		#后端真实IPproxy_set_header Client-IP $remote_addr;	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;	#转发地址proxy_pass http://http_backend;}
}

6.执行consul-template命令，主要是将模板数据进行复制同时将参数不全，重新加载nginx

nohup consul-template -consul-addr 192.168.218.214:8500 \
-template "/root/consul/nginx.ctmpl:/usr/local/nginx/conf/vhost/shiki.conf:/usr/local/nginx/sbin/nginx -s reload" \
--log-level=info &

7.查看验证

cat /usr/local/nginx/conf/vhost/shiki.conf
