nginx安装命令-CentOS 6

一、准备工作

(Sheng注：我这里使用filezilla上传文件到服务器，当然你也可以直接在线安装)

1.安装环境
 yum install gcc-c++ -y
 yum install -y pcre pcre-devel
 yum install -y zlib zlib-devel
 yum install -y openssl openssl-dev
 // 创建文件夹
 去var目录下创建temp，temp下创建nginx作为临时目录
进入文件夹：cd /var 创建文件夹：mkdir temp进入文件夹：cd temp创建文件夹：mkdir nginx
 // 进入上传的目录，解压缩
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0 // 进入文件夹
// 运行解压后的文件下的configure进行配置参数，粘贴如下配置（prefix=后面就是真实安装软件的位置）
./configure \
--prefix=/usr/local/nginx \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi
上边将临时文件目录指定为/var/temp/nginx，需要在/var 下创建 temp 及 nginx 目录

二、安装

2.编译安装
make
make install
至此nginx已经安装在了/usr/local目录下
3.启动nginx
cd /usr/local/nginx // 进入安装好的nginx目录
cd sbin // 进入可以运行文件目录
./nginx // 启动nginx，默认是80端口，所以需要去把80端口打开(其实默认会打开的)
 vim /etc/sysconfig/iptables // 进入配置文件开启80端口
 service iptables restart // 修改配置文件后重启服务
 4.停止
 cd /usr/local/nginx/sbin 
./nginx -s quit // 停止nginx
5.重启nginx
./nginx -s quit // 先停止再重启
./nginx
// 加载配置文件（修改了nginx.conf后用下面命令）
./nginx -s reload

三、开机自启动脚本

vi /etc/init.d/nginx // 该init.d文件夹下键nginx，放入下面的shell脚本

shell脚本：

(Sheng注：如果报错请仔细查看报错的行，可能是回车换行没粘贴上)

    start

    reload

    status $prog
    RETVAL=$?
    ;;

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

chmod a+x /etc/init.d/nginx  //(a+x ==> all user can execute 所有用户可执行)

/etc/init.d/nginx status // 查看状态
/etc/init.d/nginx start // 启动
/etc/init.d/nginx restart // 重启

加入开机自启动

vi /etc/rc.local
// 配置文件中加入一行，保存并退出，下次重启会生效 
/etc/init.d/nginx start
