centos7安装与配置nginx1.11,开机启动

一、官网下载安装包

    http://nginx.org/en/download.html,选择适合Linux的版本,这里选择最新的版本,下载到本地后上传到服务器或者centos下直接wget命令下载。html

    切换到/usr/local目录,下载软件包nginx

1
2
# cd /usr/local
# wget http://nginx.org/download/nginx-1.11.5.tar.gz

二、安装nginx

先执行如下命令,安装nginx依赖库,若是缺乏依赖库,可能会安装失败,具体能够参考文章后面的错误提示信息。c++

# yum install gcc-c++
# yum install pcre
# yum install pcre-devel
# yum install zlib 
# yum install zlib-devel
# yum install openssl
# yum install openssl-devel

    解压安装包vim

1
# tar -zxvf nginx-1.11.5.tar.gz

    nginx被解压到了/usr/local/nginx-1.11.5 目录下(不要把压缩包解压到/usr/local/nginx目录下,或者将解压后的目录重命名为nginx,由于nginx会默认安装到/usr/local/nginx目录下),切换到nginx-1.11.5/目录centos

1
# cd /usr/local/nginx-1.11.5/

    执行# ./configurebash

1
# ./configure

    该操做会检测当前系统环境,以确保能成功安装nginx,执行该操做后可能会出现如下几种提示:服务器

    checking for OSui

     + Linux 3.10.0-123.el7.x86_64 x86_64spa

    checking for C compiler ... not foundrest

    ./configure: error: C compiler cc is not found

    若是出现以上错误提示信息,执行yum install gcc-c++安装gcc,

    ./configure: error: the HTTP rewrite module requires the PCRE library.

    You can either disable the module by using --without-http_rewrite_module

    option, or install the PCRE library into the system, or build the PCRE library

    statically from the source with nginx by using --with-pcre=<path> option.

    若是出现上面提示,表示缺乏PCRE库

    ./configure: error: the HTTP gzip module requires the zlib library.

    You can either disable the module by using --without-http_gzip_module

    option, or install the zlib library into the system, or build the zlib library

    statically from the source with nginx by using --with-zlib=<path> option.

    若是出现以上提示,表示缺乏zlib库

 

    若是没有出现./configure: error提示,表示当前环境能够安装nginx,执行make和make install编译nginx

1
2
# make
# make install

    没有出错的话,表示nginx已经成功安装完成,默认安装位置为/usr/local/nginx,以前的/usr/local/nginx-1.11.5/能够删除掉了。

    若是出现cp: 'conf/koi-win' and '/usr/local/nginx/conf/koi-win' are the same file,多是你把安装包解压到了/usr/local/nginx目录,解决办法是将该目录重命名为其余名称后再执行make,make install.

三、配置nginx开机启动

    切换到/lib/systemd/system/目录,建立nginx.service文件vim nginx.service

1
2
# cd /lib/systemd/system/
# vim nginx.service

文件内容以下:

[Unit]
Description=nginx 
After=network.target 
   
[Service] 
Type=forking 
ExecStart= /usr/local/nginx/sbin/nginx
ExecReload= /usr/local/nginx/sbin/nginx  reload
ExecStop= /usr/local/nginx/sbin/nginx  quit
PrivateTmp= true 
   
[Install] 
WantedBy=multi-user.target

    退出并保存文件,执行systemctl enable nginx.service使nginx开机启动

1
# systemctl enable nginx.service

systemctl start nginx.service    启动nginx

systemctl stop nginx.service    结束nginx

systemctl restart nginx.service    重启nginx

四、验证是否安装成功

    输入http://服务器IP/ 若是能看到nginx的界面,就表示安装成功了
