nginx 安装

nginx官方提供了一个支持yum包安装的方法，祥见：http://nginx.org/en/linux_packages.html#mainline

下载一个系统对应的rpm包，用rmp  -ivh **********.rpm 进行安装，然后在yum -y install nginx就可以安装了

这是最简单的安装方法，可以用find / -name nginx查看下安装路径，默认conf文件在/etc/nginx/下

下面还有一种安装方法，是自定义的，相对要麻烦点

1安装gcc

yum -y install gcc-c++

2.安装PCRE库

cd /usr/local/

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz

tar -zxvf pcre-8.21.tar.gz

cd pcre-8.21

./configure

make

make install

在有的操作系统上面,安装pcre后,安装的位置为/usr/local/lib/*pcre*

在redhat 64位机器之上有这样的情况.

在redhat 64位机器上, nginx可能读取的pcre文件为/lib64/libpcre.so.1文件.

所以在改用下面的软连接:

     ln -s /usr/local/lib/libpcre.so.1 /lib64/

 

3.安装zlib库

cd /usr/local/ 

wget http://zlib.net/zlib-1.2.8.tar.gz

tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8

./configure

make

make install

 

4.安装ssl

 

cd /usr/local/

wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz

tar -zxvf openssl-1.0.1c.tar.gz

./config

make

make install

5.安装nginx

 

cd /usr/local/

wget http://nginx.org/download/nginx-1.2.8.tar.gz

tar -zxvf nginx-1.2.8.tar.gz

cd nginx-1.2.8  

./configure --prefix=/usr/local/nginx 

make

make install

6启动

/usr/local/nginx/sbin/nginx

7查看是否启动

netstat -ano|grep 80 有结果输入说明启动成功

8 自启动：

编辑：vi /etc/init.d/nginx

   echo "nginx already running...."
   exit 1

   echo -n $"Starting $prog: "

        echo -n $"Stopping $prog: "
        killproc $nginxd

    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo

case "$1" in

        start
        ;;

        stop
        ;;

        reload
        ;;

        stop
        start
        ;;

        status $prog
        RETVAL=$?
        ;;

        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

同样的修改了nginx的配置文件nginx.conf，也可以使用上面的命令重新加载新的配置文件并运行，可以将此命令加入到rc.local文件中，这样开机的时候nginx就默认启动了

vi /etc/rc.local

加入一行  /etc/init.d/nginx start    保存并退出，下次重启会生效。
