一、安装Nginx准备:
1、yum -y install pcre* #将所有的pcre安装包安装上,需连网
2、下载nginx安装包
下载地址:http://nginx.org/en/download.html
二、安装:
1、解压nginx-xxx.tar.gz包
命令:tar -xvf nginx-xxx.tar.gz
2、进入解压包
命令:cd nginx-xxx
3、进行安装
命令:./configure --prefix=/usr/local/nginx-1.9 --with-http_stub_status_module
加入--with-http_stub_status_module是为了后面负载做准备
4、修改配置
命令:vim /usr/local/nginx/conf/nginx.conf,修改servername这里的服务器名称,先修改为自己的IP地址
5、启动
命令:/usr/local/nginx/sbin/nginx
6、将防火墙关闭
关闭命令: service iptables stop
永久关闭防火墙:chkconfig iptables off
7、验证结果
在浏览器上输入 http://sername 回车,看是否存在welconme nginx页面,是,表示安装成功
三、配置服务
nginx如果每次用脚本启动,比较麻烦,喜欢使用脚本,所以,特意添加nginx添加到service中的脚本,vim /etc/rc.d/init.d/nginx
该配置代码由官网提供,地址:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15

# proxy and IMAP/POP3 proxy server

prog=$(basename $nginx)

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
if [ -z "`grep $user /etc/passwd`" ]; then
useradd -M -s /bin/nologin $user

if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0

rh_status_q || exit 0

echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
二。将shell脚本放入到 /etc/rc.d/init.d/中,并执行下列命令
1:chmod +x /etc/rc.d/init.d/nginx (设置可执行权限)
2:chkconfig --add nginx (添加系统服务)
