生产上的样例安装部署步骤(公网的代理服务器)nginx转发+keepalived高可用

公网Nginx+keepalived高可用

一、 方案规划

Ip 192.168.1.128 192.168.1.138 192.168.1.136 Vip 主机名 bejmuse17 bejmuse23 默认主从 MASTER BACKUP

二、 准备材料

keepalived-1.2.18.tar.gz nginx-1.10.2.tar.gz

nginx-goodies-nginx-sticky-module-ng-08a395c66e42.zip

三、 安装 1、

依赖包的安装:

编译nginx所需的依赖包(用root用户,生产环境有yum源)

#yum install gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl openssl-devel

(生产环境,执行语句提示安装包已经安装)

2、 上传安装文件

将keepalived-1.2.18.tar.gz、nginx-1.10.2.tar.gz nginx-goodies-nginx-sticky-module-ng-08a395c66e42.zip 上传到

/home/user/yy/

3、 Nginx编译安装

(1) 解压并安装Nginx的sticky插件 cd /home/user/yy/

unzip nginx-goodies-nginx-sticky-module-ng-08a395c66e42.zip (2)解压并安装编译Nginx

#cd /home/user/yy/

#tar -zxvf nginx-1.10.2.tar.gz #cd nginx-1.10.2

#./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-

http_gzip_static_module --add-module=/home/user/yy/nginx-goodies-nginx-sticky-module-ng-08a395c66e42/ --with-stream #make && make install

(3)系统防火墙进行关闭

#service iptables stop

(4)检测是否安装成功

/usr/local/nginx/sbin/nginx -t 安装成功会显示 success

(5)启动Nginx

启动命令:

# /usr/local/nginx/sbin/nginx 重启命令:

# /usr/local/nginx/sbin/nginx -s reload

(6)设置Nginx开机启动

# vi /etc/rc.local 加入:

/usr/local/nginx/sbin/nginx

4、 Keepalived编译安装

#cd /home/user/yy/

#tar -zxvf keepalived-1.2.18.tar.gz #cd keepalived-1.2.18

#./configure --prefix=/usr/local/keepalived #make && make install

5、

将keepalived设置成系统服务(因为没有使用keepalived的默认路径安装(默认是/usr/local),安装完成之后,需要做一些工作)

#mkdir /etc/keepalived

#cp /usr/local/keepalived/etc/keepalived/keepalived.conf #/etc/keepalived/

#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ #cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ #ln -s /usr/local/sbin/keepalived /usr/sbin/ #ln -s /usr/local/keepalived/sbin/keepalived /sbin/ #chkconfig keepalived on

6、

高可用的配置(所有配置文件在修改前请自行备份)

备份:

#cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak 编辑:

#vi /etc/keepalived/keepalived.conf

(1)master
