CentOS7安装Nginx并自启动 CentOS7安装Nginx并配置自动启动的方法步骤

挨踢农民工 人气:0

1、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。

切换到/usr/local目录,下载软件包

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

2、安装nginx

先执行以下命令,安装nginx依赖库,如果缺少依赖库,可能会安装失败,具体可以参考文章后面的错误提示信息。

# 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

# 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,因为nginx会默认安装到/usr/local/nginx目录下),切换到nginx-1.11.5/目录

# cd /usr/local/nginx-1.11.5/

执行# ./configure

# ./configure

该操作会检测当前系统环境,以确保能成功安装nginx,执行该操作后可能会出现以下几种提示:

    checking for OS

     + Linux 3.10.0-123.el7.x86_64 x86_64

    checking for C compiler ... not found

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

    如果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.

    如果出现上面提示,表示缺少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.

    如果出现以上提示,表示缺少zlib库

 如果没有出现./configure: error提示,表示当前环境可以安装nginx,执行make和make install编译nginx

# 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,之前的/usr/local/nginx-1.11.5/可以删除掉了。

如果出现cp: 'conf/koi-win' and '/usr/local/nginx/conf/koi-win' are the same file,可能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他名称后再执行make,make install.

3、配置nginx开机启动

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

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

文件内容如下:

[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

# 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

4、验证是否安装成功

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