Nginx安装

[root@localhost src]# tar xf nginx-1.14.2.tar.gz 
[root@localhost src]# ls
nginx-1.14.2  nginx-1.14.2.tar.gz
[root@localhost nginx-1.14.2]# yum -y install gcc gcc-c++ autoconf automake make

#-----------./configure --help查看编译安装时nginx支持的参数
[root@localhost src]# cd nginx-1.14.2
[root@localhost nginx-1.14.2]# ls
auto     CHANGES.ru  configure  html     man     src
CHANGES  conf        contrib    LICENSE  README
[root@localhost nginx-1.14.2]# ./configure --help


[root@localhost nginx-1.14.2]# ./configure --prefix=/apps/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_ssl_module \
> --with-http_v2_module \
> --with-http_realip_module \
> --with-http_stub_status_module \
> --with-http_gzip_static_module \
> --with-pcre \
> --with-stream \
> --with-stream_ssl_module \
> --with-stream_realip_modul
(./configure --prefix=/apps/nginx --user=nginx--group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module)

/*
#-------------在安装过程中可能会出现一些错误例如：
./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option

./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.
此时不要着急需要执行如下命令，然后在对configure目录进行编译

#创建nginx用户以及nginx用户组并且nginx用户和nginx用户组需要具有/apps/nginx/的权限
[root@localhost apps]# useradd nginx -s /sbin/nologin -u 2000
/*
    建议搭建环境时，特别是搭建nginx集群的时候建议所有机器的nginx用户以及nginx用户组的id都是相同且权限相同，以避免因用户权限而导致有些文件不能读取；例如上传文件时，当经过某一台nginx的服务器时，其所属权限为当前nginx的权限；如果其他服务器上的nginx与当前服务器的nginx用户权限不同就会导致如不能查看该文件，或者执行，读或者写的权限，造成应用出现一些非必现的bug

[root@localhost nginx-1.14.2]# /apps/nginx/sbin/nginx -v
nginx version: nginx/1.14.2

#-----------查看nginx的版本以及nginx编译安装时所添加的参数
[root@localhost nginx-1.14.2]# /apps/nginx/sbin/nginx -V

#-----------------nginx -t查看当前nginx配置是否正确，在每次修改nginx之后建议都要进行nginx -t以保证在热启动nginx之前，nginx的配置是正确的
[root@localhost ~]# /apps/nginx/sbin/nginx -t        
nginx: the configuration file /apps/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx/conf/nginx.conf test is successful
#-----------------(将nginx的配置修改错误使用nginx -t显示如下)直接告诉我们错误发生在地18行
[root@localhost ~]# vi /apps/nginx/conf/nginx.conf
[root@localhost ~]# /apps/nginx/sbin/nginx -t
nginx: [emerg] directive "http" has no opening "{" in /apps/nginx/conf/nginx.conf:18
nginx: configuration file /apps/nginx/conf/nginx.conf test failed

#----------------nginx的停止
[root@localhost ~]# ps -ef|grep nginx
root       8442      1  0 22:49 ?        00:00:00 nginx: master process nginx
nginx      8443   8442  0 22:49 ?        00:00:00 nginx: worker process

[root@localhost ~]# ps -ef|grep nginx
root       8448   8411  0 22:49 pts/0    00:00:00 grep --color=auto nginx

#----------------nginx的热启动(只会重启woker进程)
[root@localhost ~]# nginx -s reload
[root@localhost ~]# ps -ef |grep nginx
root       1162      1  0 00:00 ?        00:00:00 nginx: master process /apps/nginx/sbin/nginx -c /apps/nginx/conf/nginx.conf
nginx      1221   1162  0 00:18 ?        00:00:00 nginx: worker process
root       1223   1044  0 00:18 pts/0    00:00:00 grep --color=auto nginx
[root@localhost ~]# nginx -s reload
