默认基于centos系统进行安装
很多内容和写的另外一篇博客nginx+keepalived+pgsql+mysql+redis+tomcat离线部署过程有部分重合
因为一些在线安装, 无非是
rpm/tar.gz压缩包: 与离线差不多有一些服务器会自带java8

下载: 官网下载tar.gz压缩包, apache-tomcat-8.5.81.tar.gz为例
上传: 将压缩包上传到服务器的一个目录上
解压: tar -zxvf apache-tomcat-8.5.81.tar.gz
重命名: mv apache-tomcat-8.5.81.tar.gz tomcat
移动到安装目录(位置随意): mv tomcat /usr/local/tomcat
创建tomcat.service, vi /etc/systemd/system/tomcat.service, 并输入(注意java路径和tomcat路径):

也需要先提前安装5.1中的内容
下载: https://nginx.org/en/download.html, 中的Stable version, 以nginx-1.24.0.tar.gz为例
上传服务器
解压: tar -zxvf nginx-1.24.0.tar.gz
切换目录: cd nginx-1.24.0
配置: ./configure
配置(选, 如果需要https, 安装ssl证书的话): ./configure --with-http_ssl_module
编译: make
安装: make install, 默认安装目录/usr/local/nginx, 也可想redis一样指定安装目录
修改配置文件(简单配置)
http下与server同级的地方upstream myservers {
# 可多个
# 输入ip端口和权重
server 127.0.0.1:8080 weight=1;
}
server节点下location中修改server {
listen 80;
server_name: localhost;
location / {
proxy_pass http://myservers;
proxy_redirect default;
#root html;
#index index.html index.htm;
}
}
注册nginx.service, vim /etc/systemd/system/nginx.service

重载: systemctl daemon-reload
开机自启: systemctl enable nginx
启动: systemctl start nginx
重载配置(修改配置后需要): systemctl reload nginx
测试能否实现转发, 访问机器上的80端口, 看能否转发到8080端口上
复制到/opt下
解压: tar -zxvf keepalived-2.2.7.tar.gz
进入目录: cd keepalived-2.2.7/
配置: ./configure --prefix=/usr/local/keepalived, 指定安装目录
编译: make
安装: make install
进入安装目录: cd /usr/local/keepalived/
会自动生成:
drwxr-xr-x. 2 root root 21 May 5 03:19 bin
drwxr-xr-x. 4 root root 41 May 5 03:19 etc
drwxr-xr-x. 2 root root 24 May 5 03:19 sbin
drwxr-xr-x. 5 root root 40 May 5 03:19 share
新建配置文件(同目录下有配置文件的demo可参考): vim ./etc/keepalived/keepalived.conf
备用服务器上的state 填入BACK_UP, 优先级小一点. 其他一样
! Configuration File for keepalived
# 定义虚拟路由, 必须叫VI_1
vrrp_instance VI_1 {
state MASTER #设置为主服务器, 备份服务器设置为BACKUP
interface eth0 #监控的网络接口(ifconfig或者ip addr指令找出网卡)
priority 100 #(优先级, 主机大一点, 备份机小一点)
virtual_router_id 99 #同一个vrrp_instance下routerId必须是一致的
authentication {
auth_type PASS #vrrp认证方式主备必须一致
auth_pass 12345 #密码
}
virtual_ipaddress {
127.0.0.88 #虚拟ip, 主从一致, 可配置多个
}
}
修改service
使用离线方式安装keepalived后会自动生成keepalived.service文件位置在: /usr/lib/systemd/system/keepalived.service
注: 一般系统的或者安装程序自动生成的service文件会在/usr/lib/systemd/system下
用户自己配置的service一般会放在/etc/systemd/system/下, 两个目录下都可以用systemctl命令操作到.
默认的keepalived.service文件

防火墙放行vrrp通信: firewall-cmd --add-rich-rule='rule protocol value="vrrp" accept' --permanent
防火墙重载: firewall-cmd --reload
检查通信是否正常: tcpdump -i eth0-nn host 224.0.0.18, 只有一个等级高为正常

docker run: 运行一个容器, 如果没有镜像(docker images查看)会自动下载最新的并运行-d: 后台运行-p 8081:8081: 端口影响, 将主机的8081映射到容器的8081上, 前面是主机的--name: 指明容器的名称, 不填默认随机单词-v host_path:container_path: 将主机路径挂接到容器内路径, 这样日志和数据会保存在主机上, 不会随着容器删除而删除--restart=always: 重启策略, always是当意外停止或者正常停止时候(包括重启机器或者docker)会自动运行该容器docker ps -a, 其中-a是显示所有容器(包括停止的, 不加的话是显示正在运行的)status中看到nexus看到是Restarting, 证明没有启动成功, 在重启中. 通过查找日志docker logs nexus的最上面会发现mkdir: cannot create directory '../sonatype-work/nexus3/log': Permission denied, 说是权限不足, 创建sonatype-work目录时候被拒绝了, 因为sonatype-work是运行数据目录, 包括日志和数据等, 所以可以判断是-v挂接的主机路径权限问题, 通过chown -R 200 /usr/local/nexus/nexus-data/给目录赋予用户id为200的即可, 因为nexus docker镜像使用的用户id是200, 因为在官网https://hub.docker.com/r/sonatype/nexus3/有提到A persistent directory, /nexus-data, is used for configuration, logs, and storage. This directory needs to be writable by the Nexus process, which runs as UID 200., 设置完再次通过docker start nexus运行ip:80801admin, 密码在-v前面的主机目录内的admin.password, 使用cat/vim查看, 直接复制出来登录上然后按照提醒重置密码.本软件的安装是基于Kylin Linux Advanced Server V10 (Lance), 系统镜像: 麒麟官网镜像下载中的海光版, 点进去是x86_64后缀.
