之前在wordpress上有写过一篇安装的步骤：源码编译安装nginx。

但是今天找到了一个更简单的方法，简单几步就能装好：

• 解决依赖关系和添加用户

# 安装依赖项
## centos
yum install prce pcre-devel openssl openssl-devel -y
## ubuntu
apt-get install openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev
 
# 添加用户
useradd www -s /sbin/nologin -M

• 下载安装

wget http://mirrors.163.com/nginx/debian/pool/nginx/n/nginx/nginx_1.12.2.orig.tar.gz
tar -zxvf nginx_1.12.2.orig.tar.gz
cd nginx-1.12.2
./configure --user=www --group=www --prefix=/usr/local/nginx-1.12.2 --with-http_stub_status_module --with-http_ssl_module
make && make install
ln -s /usr/local/nginx-1.12.2/ /usr/local/nginx

• 添加配置文件和服务

添加配置文件目录：

mkdir /etc/nginx
cp /usr/local/nginx/conf/* /etc/nginx

然后复制以下内容到/etc/init.d/nginx ：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/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 0

nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -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:.*--user=" | sed ''s/[^*]*--user=\([^ ]*\).*/\1/g'' -`
   if [ -n "$user" ]; then
      if [ -z "`grep $user /etc/passwd`" ]; then
         useradd -M -s /bin/nologin $user
      fi
      options=`$nginx -V 2>&1 | grep ''configure arguments:''`
      for opt in $options; do
          if [ `echo $opt | grep ''.*-temp-path''` ]; then
              value=`echo $opt | cut -d "=" -f 2`
              if [ ! -d "$value" ]; then
                  # echo "creating" $value
                  mkdir -p $value && chown -R $user $value
              fi
          fi
       done
    fi
}

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
        $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 2
esac

• 启动服务

service nginx start
