Linux下nginx安装教程

 

一、准备工作

Nginx安装版本：nginx-1.8.1.tar.gz

Linux环境：

 

 

 二、安装nginx

1、把nginx-1.8.1.tar.gz放到/usr/locad/下

2、解压安装包:tar -xvf nginx-1.8.1.tar.gz

3、修改安装包名称:mv nginx-1.8.1 nginx

4、进入nginx目录:cd nginx

5、配置./configure

6、编译安装make && make install

 

三、验证是否成功启动

1、在/usr/local/nginx/sbin目录执行./nginx -r reload启动nginx

2、在浏览器中输入http://ip:80出现如下界面，表示启动成功

 

  

四、安装过程遇见问题

1、问题1，执行./configure报错

 

./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.

 

  

解决办法：

执行：yum -y install pcre-devel命令即可

 

  

2、问题2，./nginx -s reload重启时报错

 nginx: [alert] could not open error log file: open() "/usr/local/nginx/logs/error.log" failed (2: No such file or directory)

解决方法：

提示没有这个文件，是因为在nginx目录下没有logs文件夹，创建一个在启动即可

cd /usr/local/nginx

mkdir logs

cd sbin

./nginx -s reload

 

3、问题3，目录为同一级

make[1]: Leaving directory `/usr/local/nginx'

make -f objs/Makefile install

make[1]: Entering directory `/usr/local/nginx'

test -d '/usr/local/nginx' || mkdir -p '/usr/local/nginx'

test -d '/usr/local/nginx/sbin' || mkdir -p '/usr/local/nginx/sbin'

test ! -f '/usr/local/nginx/sbin/nginx' || mv '/usr/local/nginx/sbin/nginx' '/usr/local/nginx/sbin/nginx.old'

cp objs/nginx '/usr/local/nginx/sbin/nginx'

test -d '/usr/local/nginx/conf' || mkdir -p '/usr/local/nginx/conf'

cp conf/koi-win '/usr/local/nginx/conf'

cp: "conf/koi-win" 与"/usr/local/nginx/conf/koi-win" 为同一文件

make[1]: *** [install] 错误 1

make[1]: Leaving directory `/usr/local/nginx'

make: *** [install] 错误 2

 

这是因为编译安装过一次，再次编译安装是，sbin等文件夹已经存在所以会包这个错误，可以删除该文件夹再次安装，或者忽略该错误

 

  

4、问题4，解决 nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

使用/usr/local/nginx/sbin/nginx -s reload 重新读取配置文件出错

 

[root@localhost nginx]/usr/local/nginx/sbin/nginx -s reload

提示 nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

 

[root@localhost nginx]# cd logs

[root@localhost logs]# ls

access.log error.log nginx-access.log nginx_error.log

果然没有/usr/local/nginx/logs/nginx.pid 文件

 

解决方法：用指定文件加载nginx配置文件

[root@localhost nginx]/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
