负载均衡服务器Nginx安装教程

【keepalived安装】

下载keepalived到/usr/local/src
tar -xzvf keepalived-1.2.19.tar.gz
cd /usr/local/src/keepalived-1.2.19

配置

./configure –prefix=/usr/local/keepalived

编译

make && make install

复制建立服务启动脚本，以便使用service命令控制之：

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
chmod +x /etc/init.d/keepalived
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

启动keepalived

service keepalived start|stop

【nginx安装】

nginx安装之前要先安装pcre、openssl、zlib
注意：./configure –prefix=/usr/local/keepalived
configure:error:!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files.
解决方法：安装openssl，同时pcre也一起安装一下，gcc、zlib没有安装也可以安装一下
yum -y install pcre pcre-devel openssl openssl-devel zlib* gcc

解压

下载nginx到/usr/local/src
tar -xzvf nginx-1.11.4.tar.gz
cd nginx-1.11.4

执行配置文件

./configure

编译

make && make install

启动

cd /usr/local/nginx/sbin
./nginx

重启

cd /usr/local/nginx/sbin
./nginx -s reload

检验配置文件是否正确

检验：
ps -ef|grep nginx
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
或者
cd /usr/local/nginx/sbin
./nginx -t
