keepalived nginx安裝配置

軟體版本： pcre8.36 keepalived1.2.19 nginx1.8.0 安裝步驟安裝pcre tar -zxvf pcre-8.36.tar.gz cd pcre-8.36 ./configure --prefix=/usr/local/pcre make && make install 安裝keepalived tar -zxvf keepalived-1.2.19.tar.gz cd keepalived-1.2.19 ./configure --prefix=/usr/local/keepalived make && make install cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ mkdir –pv /etc/keepalived cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ ln -s /usr/local/keepalived/sbin/keepalived /sbin/ chkconfig keepalived on 安裝nginx tar -zxvf nginx-1.8.0.tar.gz cd nginx-1.8.0 ./configure --prefix=/usr/local/nginx --with-pcre=/usr/local/pcre/

make && make install

啟動和停止nginx: 啟動：進入到安裝之後$的sbin目錄，執行./nginx 停止：./nginx –s stop 檢查是否安裝成功：進入到安裝之後$的sbin目錄，執行./nginx -t keepalived 啟動：service keepalived start 停止：service keepalived stop配置配置keepalived 主備keepalived的配置大致相同，不同之處在於state和priority。如下所示： ! configuration file for keepalived #配置報警郵件 global_defs notification_email_from [email protected] smtp_server 192.168.200.1 smtp_connect_timeout 30 router_id lvs_devel }#配置keepalived伺服器例項 vrrp_instance vi_1 virtual_ipaddress

}

配置nginx
nginx的基本配置如下所示：
#user nobody; #使用者名稱
worker_processes auto; #處理程序個數，一般為自動分配
error_log logs/error.log; #錯誤日誌記錄位置
#error_log logs/error.log notice; #notice/info等為記錄錯誤的級別
#error_log logs/error.log info;
pid logs/nginx.pid; #程序記錄檔案
#配置負載均衡，server為nginx伺服器
upstream nginx
#配置處理請求server
server
location / 
#error_page 404 /404.html; #配置錯誤頁面
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html 
}server
location / 
error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html 
}}負載均衡nginx 的 upstream目前支援 4 種方式的分配
輪詢（預設）
每個請求按時間順序逐一分配到不同的後端伺服器，如果後端伺服器down掉，能自動剔除。
weight
定輪詢機率，weight和訪問比率成正比，用於後端伺服器效能不均的情況。
ip_hash
每個請求按訪問ip的hash結果分配，這樣每個訪客固定訪問乙個後端伺服器，可以解決session的問題。
fair（第三方）
按後端伺服器的響應時間來分配請求，響應時間短的優先分配。
在http中upstream配置中，clouder是起的負載均衡伺服器或者反向**的名稱。
upstream clouder
