1. 官网下载nginx安装包
2. 解压安装包
3. ./configure
./configure 默认安装路径为/usr/local/nginx，如果要自定义安装路径，增加 --prefix=自定义路径
4. 若编译没有报错，则运行 make && make install
5. 配置nginx为系统服务
1. 在/etc/init.d/目录下创建nginx文件，写入如下代码：
#!/bin/sh##nginx - this script starts and stops the nginx daemin## chkconfig: - 85 15# description: Nginx is an HTTP(S) server, HTTP(S) reverse \# proxy and IMAP/POP3 proxy server# processname: nginx# config: /usr/local/nginx/conf/nginx.conf# pidfile: /usr/local/nginx/logs/nginx.pid# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ "$NETWORKING" = "no" ] && exit 0nginx="/usr/local/nginx/sbin/nginx"prog=$(basename $nginx)NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"lockfile=/var/lock/subsys/nginxstart() {[ -x $nginx ] || exit 5[ -f $NGINX_CONF_FILE ] || exit 6echo -n $"Starting $prog: "daemon $nginx -c $NGINX_CONF_FILEretval=$?echo[ $retval -eq 0 ] && touch $lockfilereturn $retval}stop() {echo -n $"Stopping $prog: "killproc $prog -QUITretval=$?echo[ $retval -eq 0 ] && rm -f $lockfilereturn $retval}restart() {configtest || return $?stopstart}reload() {configtest || return $?echo -n $"Reloading $prog: "killproc $nginx -HUPRETVAL=$?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" instart)rh_status_q && exit 0$1;;stop)rh_status_q || exit 0$1;;restart|configtest)$1;;reload)rh_status_q || exit 7$1;;force-reload)force_reload;;status)rh_status;;condrestart|try-restart)rh_status_q || exit 0;;*)echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"exit 2esac 如果是默认安装，则直接将代码复制进去即可，如果自定义了安装路径，需要修改
nginx跟NGINX_CONF_FILE这两个参数为实际路径。
2. chmod a+x /etc/init.d/nginx
6. 设置nginx为有效命令:
ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
