centos 部署安装环境及docker容器应用_centos 部署网心云

系统内核要求3.1以上

虚拟机网络配置

vi /etc/sysconfig/network-scripts/ifcfg-ens33 
MM_CONTROLLED=no
ONBOOT=yes

ip addr
apt-get install net-tools
yum安装
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/python-2.7.5-89.el7.x86_64.rpm; 
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm; 
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm;
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm;
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm;

安装Docker
##查看内核：
uname -r 内核必须3.1以上的版本
##移除历史版本
yum remove docker docker-common container-selinux docker-selinux docker-engine

##更新yum
yum update
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast

yum install -y docker-ce
systemctl start docker

####docker 安装工作目录挂载
docker info  # 查看docker位置，默认在/var/lib/docker
systemctl stop docker # 停止docker服务
df -h  # 查看磁盘空间大的位置
mkdir -p /home/docker  # 创建docker文件夹

# 迁移/var/lib/docker目录下的文件到目标位置
sudo rsync -avz /var/lib/docker /home/

#编辑daemon.json
sudo vim /etc/docker/daemon.json

# 在vim添加以下内容，路径是目标docker路径

{
  "graph": "/home/docker/"
}
# 重新加载docker并重启docker 如果发下无法重启 先执行 删除旧的目录命令

rm -rf /var/lib/docker  删除旧的目录命令 
systemctl daemon-reload && systemctl restart docker

安装jdk
docker search jdk8
docker pull kdvolder/jdk8
docker run -di -v /home/java:/home/java --name=jdk1.8 kdvolder/jdk8

docker exec -i -t  jdk1.8 /bin/bash

安装mysql
docker search mysql
docker pull mysql:5.7
sudo docker run -p 3306:3306 --name mysql -v /mydata/mysql/log:/var/log/mysql -v /mydata/mysql/data:/var/lib/mysql -v /mydata/mysql/conf:/etc/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

安装oracle
docker search oracle
docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
docker run -it -d -p 1521:1521 -v /data/oracle:/data/oracle -v /server/dpdump:/opt/oracle/dpdump --name oracle11g registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
docker exec -it oracle_11g /bin/bash

su root
密码：helowin
vi /etc/profile
export ORACLE_HOME=/home/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH
##创建软连接
 ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
 
###登录sqlplus并修改sys、system用户密码
sqlplus /nolog   --登录
conn /as sysdba  --
alter user system identified by system;--修改system用户账号密码；
alter user sys identified by 123456;--修改sys用户账号密码；
create user test identified by test; -- 创建内部管理员账号密码；
grant connect,resource,dba to test; --将dba权限授权给内部管理员账号和密码；
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED; --修改密码规则策略为密码永不过期；（会出现坑，后面讲解）
alter system set processes=1000 scope=spfile; --修改数据库最大连接数据；

alter database mount;
alter database open;

###redis 安装
docker images
docker pull redis:5.0.9
## 创建目录
mkdir -p /home/redis/data /home/redis/conf
touch /home/redis/data /home/redis/conf/redis.conf

#bind 127.0.0.1
protected-mode no
requirepass 123456  
docker run -d --name redis -p 6379:6379 -v /home/redis/conf/redis.conf:/redis.conf -v /home/redis/data:/data redis:5.0.9 redis-server --appendonly yes
-d 后台运行
–name 指定容器名称
-p 端口映射到主机的端口 （-p 主机端口：容器端口）
-v 将主机目录挂载到容器的目录
redis-server --appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置

###nginx安装
mkdir -p /home/nginx/html

mkdir -p /home/nginx/conf

mkdir -p /home/nginx/logs

docker pull nginx

#先启动
docker run -p 9999:80 --name mynginx -d nginx
#拷贝配置文件
docker cp -a mynginx:/etc/nginx/ /home/nginx/conf
#修改配置文件

#再启动
docker run -p 9999:80 --name mynginx -v /home/nginx/www:/www -v /home/nginx/conf/nginx:/etc/nginx -v /home/nginx/logs:/wwwlogs -d nginx
#-p 9999:80：将容器的80端口映射到主机的9999端口
#--name nginx：将容器命名为mynginx
#-v /home/nginx/html:/html：将主机中当前目录下的www挂载到容器的/www
#-v /home/nginx/conf:/etc/nginx：将主机中当前目录下的nginx.conf挂载到容的/etc/nginx/nginx.conf
#-v /home/nginx/logs:/nginxlogs：将主机中当前目录下的logs挂载到容器的/nginxlogs

#编辑防火墙配置文件
systemctl stop firewalld.service systemctl status firewalld.service
