 gcc \
 gcc-c++ \
 make \
 openssl-devel \

useradd -s /sbin/nologin -M nginx --建立一個不能登陸服務器，而且沒有家目錄的用戶 css

tar vxf nginx-?.tar.gz ---解壓nginx軟件包html

cd nginx-1.13.9 --切換到解壓目錄裏java

Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用

二、源碼編譯keepalivednginx

yum -y install \         //安裝插件
> popt-devel \
> kernel-devel \
> openssl-devel
tar xvf keepalived-1.4.2.tar.gz   --解壓keepalived壓縮包
 cd keepalived-1.4.2            --切換到解壓目錄
 ./configure --prefix=/           --配置
 make && make install        --編譯與安裝

cp keepalived/etc/init.d/keepalived /etc/init.d/c++

//如下編輯keepalived配置文件
cd /etc/keepalived/
vi keepalived.confweb

! Configuration File for keepalived
global_defs {
        route_id NGINX-01
   }
vrrp_script nginx {
        script "/opt/nginx.sh"
        interval 2
        weight -10
}
vrrp_instance VI_1 {
    state MASTER
    interface ens32
    virtual_router_id 51
    priority 150
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    track_script {
        nginx
        }
    virtual_ipaddress {
        192.168.80.100
    }
}
//注意，主備的優先級配置的相差50

建立腳本文件
判斷keepalived進程是否存在，在就啓動nginx不在就關閉
vi /opt/nginx.sh

#!/bin/bash 
#Filename:nginx.sh
A=$(ps -ef | grep keepalived | grep -v grep | wc -l)
if [ $A -gt 0 ]; then
        /etc/init.d/nginx start
else
        /etc/init.d/nginx stop
fi

chmod +x /opt/nginx.sh --給腳本文件加執行權限

service keepalived start --啓動keepalived，會連nginx一塊啓動

ip addr show dev ens32 --查看漂移地址是否生成
Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用

---------------測試驗證------------
[root@lvs01 keepalived]# systemctl stop keepalived    //關閉keepalived服務
[root@lvs01 keepalived]# killall -9 nginx              //關閉nignx服務
[root@lvs01 keepalived]# netstat -anpt | grep 80       //80端口已中止運行

[root@lvs01 keepalived]# systemctl start keepalived     //開啓keepalived服務
[root@lvs01 keepalived]# netstat -anpt | grep 80       //nginx隨keepalived啓動

---------------------配置從服務器--------------------------------
一、源碼編譯安裝nginx
從服務器源碼安裝nginx，和主服務器同樣，根據主服務器操做在作一遍
須要修改的地方
Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用

二、源碼安裝keepalived
操做和主服務器相同,在寫到nginx.sh腳本文件時不一樣，其它的操做如出一轍。

#!/bin/bash
#Filename:nginx.sh
A=$(ip addr | grep 192.168.80.188/32 | grep -v grep | wc -l)
if [ $A -gt 0 ]; then
        /etc/init.d/nginx start
else
        /etc/init.d/nginx stop
fi

chmod +x /opt/nginx.sh --給腳本執行權限

service keepalived start --啓動 keepalived

----------測試驗證----------
一：查看從服務器狀態
[root@lvs02 ~]# ip addr show dev ens33 //查看漂移地址
Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
//因爲主服務器在運行，漂移地址並未同步過來

//當主服務器在運行的時候，從服務器虛擬地址並未生成，nginx服務並未隨keepalived啓動
二：模擬主服務故障

  1. 主服務器
    Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用

killall 命令須要安裝 : yum install psmisc -y
//80端口已不運行
[root@lvs01 ~]# ip addr show dev ens32
Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
//漂移地址消失，不工做

  1. 從服務器
    [root@lvs02 ~]# ip addr show dev ens32 //查看漂移地址
    Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
    //漂移地址自動生成
    [root@lvs02 ~]# netstat -anpt | grep 80
    Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用

  2. 主服務器 
    [root@lvs01 ~]# service keepalived start
[root@lvs01 ~]# ip addr show dev ens33

[root@lvs01 ~]# netstat -anpt | grep 80

//主服務器已恢復工做

  1. 從服務器
    [root@lvs02 ~]# ip addr show dev ens33

//漂移地址自動移除
[root@lvs02 ~]# netstat -anpt | grep 80
```\

//nginx自動中止服務
//雙機熱備驗證成功

192.168.80.103
提示:操做與192.168.80.102基本同樣
須要修改的地方就是把 SERVER AA 改爲 SERVER BB j 就能夠了

#192.168.80.102

第三部分 部署服務器池—搭建Tomcat
//如下在兩臺tomcat服務器上操做
第一步：部署第一個節點服務器TM01（192.168.80.102）
----------部署java環境，jdk---------

[root@tom01 ~]# tar xvf jdk-8u144-linux-x64.tar.gz //解壓jdk
[root@tom01 ~]# cp -r jdk1.8.0_144/ /usr/local/java //建立java源目錄
[root@tom01 ~]# vi /etc/profile
最後添加如下內容：
export JAVA_HOME=/usr/local/java
export JRE_HOME=/usr/local/java/jre
export PATH=$PATH:/usr/local/java/bin
export CLASSPATH=./:/usr/local/java/lib:/usr/local/java/jre/lib
保存退出
[root@tom01 ~]# source /etc/profile //當即生效
[root@tom01 ~]# java –version //查看版本

java環境部署完成

----------部署tomcat----------
[root@tom01 ~]# tar xvf apache-tomcat-8.5.23.tar.gz //解壓apache-tomcat
[root@tom01 ~]# cp -r apache-tomcat-8.5.23 /usr/local/tomcat8 //建立tomcat源目錄
//作個軟連接，使tomcat開啓與關閉更加方便
[root@tom01 ~]# ln -s /usr/local/tomcat8/bin/startup.sh /usr/bin/tomcatup
[root@tom01 ~]# ln -s /usr/local/tomcat8/bin/shutdown.sh /usr/bin/tomcatdown
[root@tom01 ~]# tomcatup //開啓tomcat

[root@tom01 ~]# netstat -anpt | grep 8080

Win7下訪問默認主頁：http://192.168.80.102:8080
Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
//tomcat部署成功

  1. 服務器池中有兩臺tomcat服務器，爲了便於識別，主頁上添加點標記
    [root@tom01 ~]# vi /usr/local/tomcat8/webapps/ROOT/index.jsp
    添加一行內容：
    Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
    保存退出
    [root@tom01 ~]# tomcatdown
    [root@tom01 ~]# tomcatup //重啓
    //再次訪問默認主頁http://192.168.80.102:8080
    Centos 7 Nginx+Keepalived+Tomcat 源碼安裝與運用
