這篇文章主要為大家介紹了永中文檔在線轉(zhuǎn)換預(yù)覽基于nginx配置部署方案的實(shí)現(xiàn)，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

永中文檔在線轉(zhuǎn)換預(yù)覽雙活實(shí)現(xiàn)方案

永中文檔在線轉(zhuǎn)換預(yù)覽服務(wù) 是永中軟件股份有限公司基于十多年核心技術(shù)積累、面向移動(dòng)互聯(lián)領(lǐng)域推出的一款文檔處理軟件。永中采用自主可控核心技術(shù)，具備快速技術(shù)和服務(wù)響應(yīng)能力，把文檔原樣輸出為 HTML，圖片等，即點(diǎn)即得、無(wú)需下載、保護(hù)文檔隱私，快速高效，輕松實(shí)現(xiàn)文檔在線安全閱讀。?

實(shí)現(xiàn)目標(biāo)

通過(guò)nginx實(shí)現(xiàn)業(yè)務(wù)fcsserver負(fù)載均衡，后端可以動(dòng)態(tài)擴(kuò)展應(yīng)用服務(wù)器
nginx通過(guò)keepalived實(shí)現(xiàn)高可用，解決單點(diǎn)故障
通過(guò)keepalived實(shí)現(xiàn)nginx雙活配置，解決nginx主備資源使用率50%問題
通過(guò)dns輪詢解析域名到雙活vip，達(dá)到負(fù)載均衡效果
后期nginx達(dá)到瓶頸應(yīng)考慮lvs+keepalived+nginx架構(gòu)，動(dòng)態(tài)擴(kuò)展nginx服務(wù)器

環(huán)境準(zhǔn)備

服務(wù)器可以連通外網(wǎng)或者有內(nèi)網(wǎng)yum源服務(wù)器，本次實(shí)驗(yàn)服務(wù)器可連通外網(wǎng)
nginx01和nginx02服務(wù)器需要在同一網(wǎng)段的網(wǎng)絡(luò)內(nèi)
保證各服務(wù)器之前網(wǎng)絡(luò)互通
保證服務(wù)器的防火墻和selinux關(guān)閉
必須對(duì)外提供域名訪問，否則只能使用其中一個(gè)vip
內(nèi)網(wǎng)部署DNS服務(wù)器，模擬DNS輪詢解析

1、網(wǎng)絡(luò)架構(gòu)

2、實(shí)驗(yàn)服務(wù)器分布

主機(jī)	ip	操作系統(tǒng)	軟件	端口	vip
nginx01	192.168.56.101	Centos7.6	nginx keepalived	80	192.168.56.200
nginx02	192.168.56.106	Centos7.6	nginx keepalived	80	192.168.56.201
fcs01	192.168.56.101	Centos7.6	tomcat	8080
fcs02	192.168.56.106	Centos7.6	tomcat	8080
共享存儲(chǔ)	192.168.56.108	Centos7.6	nfs
緩存	192.168.56.108	Centos7.6	redis	6379
內(nèi)部DNS	192.168.56.108	Centos7.6	bind	53

3、redis

部署服務(wù)器：192.168.56.108

3.1 配置redis

/etc/redis.conf

# 監(jiān)聽地址
bind 0.0.0.0
# 認(rèn)證密碼
requirepass yozosoft

3.2 啟動(dòng)redis

systemctl enable redis --now && systemctl status redis

4、nfs

4.1 配置nfs

192.168.56.108（服務(wù)端）

# 創(chuàng)建存儲(chǔ)目錄
mkdir -p /opt/yozo/data
# 修改權(quán)限
chown -R nfsnobody.nfsnobody /opt/yozo/data
# 修改配置文件
vim /etc/exports
	/opt/yozo/data 192.168.56.0/24(rw,sync,all_squash)

192.168.56.101/192.168.56.106（客戶端）

# 創(chuàng)建掛載點(diǎn)
mkdir -p /opt/yozo/data
# 掛載nfs共享目錄
mount -t nfs 192.168.56.108:/opt/yozo/data /opt/yozo/data

4.2 啟動(dòng)nfs

systemctl enable rpcbind nfs --now && systemctl status rpcbind nfs

5、fcsserver

部署服務(wù)器：

192.168.56.101（fcsserver01）

192.168.56.106（fcsserver02）

5.1 部署fcs

以tomcat為中間件，本次實(shí)驗(yàn)fcs安裝目錄

/opt/yozo/fcsserver/webapps/fcsserver，/opt/yozo/fcsserver為解壓后的tomcat

部署項(xiàng)目包

mkdir opt/yozo/fcsserver/webapps/fcsserver -p
unzip fcscloud.war -d opt/yozo/fcsserver/webapps/fcsserver

修改fcsserver配置文件

# /opt/yozo/fcsserver/webapps/fcsserver/WEB-INF/classes/config.properties
inputDir=/opt/yozo/data/fcsdata/input	# 必須指定掛載共享存儲(chǔ)目錄的
outputDir=/opt/yozo/data/fcsdata/output
# 如果不提供域名，就只能配置其中一個(gè)vip；如果配置為域名，則緩存后，通過(guò)vip和fcsserver的ip將不能訪問轉(zhuǎn)換的緩存文件
viewDomain=http://www.fcsserver.com/fcsserver/

# /opt/yozo/fcsserver/webapps/fcsserver/WEB-INF/classes/application.yml
cache:                            #采用哪種緩存數(shù)據(jù)方式
    type: redis                     #local,redis,mysql(local模式只適用于單機(jī),集群部署不支持)
  redis:
    enable: true                    #redis開關(guān)(預(yù)覽設(shè)置權(quán)限時(shí)需要使用redis,并發(fā)和異步waitting機(jī)制使用redis,必開)
 redis:
    database: 1 # Redis數(shù)據(jù)庫(kù)索引（默認(rèn)為0）
    timeout: 10000 #設(shè)置客戶端超時(shí)時(shí)間，單位是毫秒，默認(rèn)為2000
    password: yozosoft #密碼
    #單機(jī)版
    host: 192.168.56.108
    port: 6379

# /opt/yozo/fcsserver/webapps/fcsserver/WEB-INF/classes/
<property name="LOG_HOME">../logs</property>

5.2 配置fcs系統(tǒng)服務(wù)

配置fcsserver.service

# cat /usr/lib/systemd/system/fcsserver.service
[Unit]
Description=fcsserver Service.
After=network.target
[Service]
Type=forking
Environment="PATH=/opt/yozo/jdk-8u251-amd64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"
WorkingDirectory=/opt/yozo/fcsserver/bin
ExecStart=/opt/yozo/fcsserver/bin/startup.sh
Restart=always
PrivateTmp=true
# 可以指定相關(guān)用戶啟動(dòng)fcsserver
# User=yozo
# Group=yozo
LimitNOFILE=65536
[Install]
WantedBy=multi-user.target

如果以普通用戶啟動(dòng)，需要將tomcat目錄屬主屬組設(shè)置成相應(yīng)賬戶

# 此次實(shí)驗(yàn)以yozo用戶啟動(dòng)
chown -R yozo. /opt/yozo/fcsserver

5.3 啟動(dòng)fcs

systemctl enable fcsserver --now && systemctl status fcsserver

6、nginx

部署服務(wù)器：

192.168.56.101（nginx01）

192.168.56.106（nginx02）

6.1 配置nginx

/etc/nginx/conf.d/fcsserver.conf配置

server {
    ....
    location ~ /fcsserver {
        add_header Cache-Control private,no-store,max-age=0,no-cache,must-revalidate,post-check=0,pre-check=0;
        proxy_redirect off;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded_Proto "http";
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_request_buffering off;
        proxy_read_timeout 7200;
        proxy_send_timeout 7200;
        proxy_pass http://fcsserver;
    }
   ....
}
upstream fcsserver {
    server 192.168.56.101:8080 fail_timeout=60s;
    server 192.168.56.106:8080 fail_timeout=60s;
    keepalive 256;
}

6.2 啟動(dòng)nginx

systemctl enable nginx --now && systemctl status nginx

7、keepalived

部署服務(wù)器：

192.168.56.101（nginx01）

192.168.56.106（nginx02）

7.1 配置keepalived

7.1.1 nginx01配置

/etc/keepalived/keepalived.conf

! Configuration File for keepalived
global_defs {
   router_id proxy1
}
vrrp_script chk_nginx {
  script "/etc/keepalived/check_nginx.sh"
  interval 2
  weight 20
  fall 3
  rise 2
}
vrrp_instance VI_1 {
    state MASTER
    interface enp0s3
    virtual_router_id 51
    priority 100                           
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.56.200                     
    }
    track_script {
        chk_nginx
    }
}
vrrp_instance VI_2 {
    state BACKUP
    interface enp0s3
    virtual_router_id 52
    priority 90                            
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.56.201                     
    }
    track_script {
        chk_nginx
    }
}

7.1.2 nginx02配置

# 備份keepalived.conf
mv /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.confbak

/etc/keepalived/keepalived.conf

! Configuration File for keepalived
global_defs {
   router_id proxy2
}
vrrp_script chk_nginx {
  script "/etc/keepalived/check_nginx.sh"
  interval 2
  weight 20
  fall 3
  rise 2
}
vrrp_instance VI_1 {
    state BACKUP
    interface enp0s8
    virtual_router_id 51
    priority 90
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.56.200
    }
    track_script {
        chk_nginx
    }
}
vrrp_instance VI_2 {
    state MASTER
    interface enp0s8
    virtual_router_id 52
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.56.201
    }
    track_script {
        chk_nginx
    }
}

雙機(jī)/etc/keepalived/check_nginx.sh

#!/bin/bash
#時(shí)間變量，用于記錄日志
d=`date --date today +%Y%m%d_%H:%M:%S`
#計(jì)算nginx進(jìn)程數(shù)量
n=`ps -C nginx --no-heading|wc -l`
#如果進(jìn)程為0，則啟動(dòng)nginx，并且再次檢測(cè)nginx進(jìn)程數(shù)量，
#如果還為0，說(shuō)明nginx無(wú)法啟動(dòng)，此時(shí)需要關(guān)閉keepalived
if [ $n -eq "0" ]; then
        /etc/init.d/nginx start
        n2=`ps -C nginx --no-heading|wc -l`
        if [ $n2 -eq "0"  ]; then
                echo "$d nginx down,keepalived will stop" >> /var/log/check_ng.log
                systemctl stop keepalived
        fi
fi

7.2 啟動(dòng)keepalived

systemctl enable keepalived --now && systemctl status keepalived

nginx01

nginx02

7.3 模擬故障

7.3.1 nginx01手動(dòng)關(guān)閉nginx

nginx故障后，keepalived會(huì)自動(dòng)啟動(dòng)nginx

7.3.2 nginx01手動(dòng)關(guān)閉keepalived

nginx01的vip將會(huì)綁定到nginx02上面，nginx02將會(huì)出現(xiàn)2個(gè)vip，2個(gè)vip均可以訪問fcsserver

8、DNS服務(wù)器部署

用于模擬公網(wǎng)DNS輪詢解析，實(shí)際使用中是在域名提供商處配置指向映射外網(wǎng)ip

8.1 配置dns

/etc/named.conf

zone "fcsserver.com" IN {
        type master;
        file "fcsserver.com.zone";
};
zone "56.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.56.zone";
};

修改權(quán)限

chown named. /var/named/ -R

8.2 啟動(dòng)dns服務(wù)

systemctl enable named --now && systemctl status named

9、驗(yàn)證

目標(biāo)：本次實(shí)驗(yàn)有2個(gè)vip 192.168.56.200 和 192.168.56.201，需要驗(yàn)證www.fcsserver.com分別解析到2個(gè)vip上，并確認(rèn)每個(gè)vip后端服務(wù)正?？捎?/p>

9.1 客戶端dns配置

測(cè)試期間，禁用其他網(wǎng)卡，只留虛擬機(jī)網(wǎng)卡

添加DNS

9.2 DNS緩存清理

9.3 域名訪問測(cè)試

測(cè)試之前需要確認(rèn)此次DNS解析是否指向所需測(cè)試的VIP，如果不是請(qǐng)刷新DNS緩存

需要測(cè)試www.fcsserver.com --> 192.168.56.200和www.fcsserver.com --> 192.168.56.201

文件轉(zhuǎn)換測(cè)試

轉(zhuǎn)換文件訪問測(cè)試

注：fcsserver的配置文件中viewDomain配置為域名，故轉(zhuǎn)換文件預(yù)覽連接只能通過(guò)www.fcsserver.com可以正常訪問，通過(guò)vip、nginx ip、fcsserver ip均不可以訪問

以上就是永中文檔在線轉(zhuǎn)換預(yù)覽雙活基于nginx的實(shí)現(xiàn)方案的詳細(xì)內(nèi)容，更多關(guān)于nginx永中文檔在線轉(zhuǎn)換預(yù)覽的資料請(qǐng)關(guān)注腳本之家其它相關(guān)文章！
