Nginx负载均服务器安装配置说明

Nginx 负载均服务器安装配置说明

1、部署环境

Linux下Suse 企业版 -64bit

IP列表

Server ip

nginx master 10.20.9.197/24

nginx backup 10.20.9.196/24

vip10.20.9.X

vip 10.20.9.X

Web server 1 10.20.5.203/24

Web server 2 10.20.5.204/24

注意：Suse与CentOs 有很大区别，需要安装组件

[root@nginx-1 ~]#zypper install gcc*

[root@nginx-1 ~]#zypper install openssl-devel

[root@nginx-1 ~]#zypper install popt-devel

以上命令如果弹出提示框全部选择2，然后数据回车键

步骤1：配置ip地址

[root@nginx-1 ~]# setup

Network configuration

Edit Devices

配置Eth0 Eth1 IP地址为列表中IP

步骤2：安装keepalived

[root@nginx-1~]#wget https://www.360docs.net/doc/dc4391643.html,/software/keepalived-1.1.19.tar.gz [root@nginx-1~]#tar zxvf keepalived-1.1.19.tar.gz

[root@nginx-1~]#cd keepalived-1.1.19

[root@nginx-1 keepalived-1.1.19]# ./configure --prefix=/usr/local/keepalived [root@nginx-1 keepalived-1.1.19]#make

[root@nginx-1 keepalived-1.1.19]#make install

[root@nginx-1~]cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

[root@nginx-1~]cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ [root@nginx-1~]cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ [root@nginx-1~]mkdir /etc/keepalived

[root@nginx-1~]cd /etc/keepalived/

步骤3：配置nginx master的keepalived配置文件

[root@nginx-2 keepalived]# vi /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

notification_email {

wangpc@https://www.360docs.net/doc/dc4391643.html,

}

notification_email_from Alexandre.Cassen@firewall.loc

smtp_server 127.0.0.1

smtp_connect_timeout 30

router_id LVS_DEVEL

}

vrrp_instance VI_1 {

state Master

# 该行为配置Nginx Master时的参数，Nginx Backup时需要修改为state Master interface eth0

virtual_router_id 51

priority 90

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

10.20.9.X

10.20.9.X

}

}

步骤4 将functions文件到etc/rc.d/init.d/

[root@nginx-1 ~]# cd/etc/rc.d/init.d/

[root@nginx-1~ ]#chmod 755 /etc/rc.d/init.d

步骤5

将consoletype 考入/sbin 目录下面

步骤6：启动keepalived ！，并查看虚拟IP 是否绑定！

步骤7：nginx 的安装和配置

创建供Nginx 使用的组和帐号：

步骤8：编译安装rewrite 模块支持包

[root@nginx-1 ~]# /etc/rc.d/init.d/keepalived start

Starting keepalived: [ OK ] [root@nginx-1 ~]# ip addr

1: lo: mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host

[root@nginx-1 ~]#/usr/sbin/groupadd www -g 48

[root@nginx-1 ~]#/usr/sbin/useradd -u 48 -g www www

[root@nginx-1~]#wget ftp://https://www.360docs.net/doc/dc4391643.html,/pub/software/programming/pcre/pcre-8.12.tar.gz （下载新版本） [root@nginx-1~]#tar zxvf pcre-8.12.tar.gz

[root@nginx-1~]#cd pcre-8.12/

[root@nginx-1~]#./configure

[root@nginx-1~]#make && make install

步骤9：编译安装Nginx

[root@nginx-1 ~]#wget http://sysoev.ru/nginx/nginx-0.7.64.tar.gz

[root@nginx-1 ~]#tar zxvf nginx-0.7.64.tar.gz

[root@nginx-1 ~]#cd nginx-0.7.64/

[root@nginx-1 ~]#./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_flv_module

[root@nginx-1 ~]#make && make install

步骤10：备份默认nginx.conf配置文件

[root@nginx-1~]#mv /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.bak

步骤11：配置Nginx （Master和Backup一样）

[root@nginx-1 ~]#vi /usr/local/nginx/conf/nginx.conf

[root@nginx-1 ~]#/usr/sbin/useradd -u 48 -g www www

}

}

#站点B负载均衡

server {

listen 80;

测试阶段配置文件，供参考

Nginx Master

keepalived.conf

nginx.conf

Nginx Backup

keepalived.conf

nginx.conf

测试：可以断开Nginx Master 的网卡，网站工作正常，关掉一台Web Server ， 工作正常。
