编译安装的步骤
configure #检查当前编译环境,生成MakeFile文件,编译的时候指定某些参数,没有找到相关的模块,是执行不过去的(报错)
make #根据MakeFile生成相关模块
make install #将模块拷贝到指定目录
一、Nginx编译安装
1、Nginx编译安装依赖下载
#Centos8
yum -y install make gcc-c++ libtool pcre pcre-devel zlib zlib-devel openssl openssl-devel perl-ExtUtils-Embed
#Centos7
yum -y install make gcc pcre-devel openssl-devel zlib-devel perl-ExtUtils-Embed
#Ubuntu
apt -y install make gcc libpcre3 libpcre3-dev openssl libssl-dev zlib1g-dev
2、创建用户nginx
[root@centos7 ~]# useradd -s /sbin/nologin -r nginx
3、安装Nginx
[root@centos7 ~]# cd /usr/local/src/
[root@centos7 src]# ll
total 10668
-rw-r--r-- 1 root root 1039530 Apr 21 2020 nginx-1.18.0.tar.gz
[root@centos7 src]# tar -xvf nginx-1.18.0.tar.gz
[root@centos7 src]# cd nginx-1.18.0/
#开始编译
./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 \
--with-file-aio
make
make install
编译选项说明:--with-http_ssl_module 开启ssl模块;--with-http_v2_module开启http 2.0版本模块;--with-stream支持tcp/udp;--user=nginx和--group=nginx可以不用指定,后期再进行修改;--with-http_realip_module开启透传IP;--with-http_stub_status_module开启状态页功能,用于监控;--with-http_gzip_static_module开启压缩功能;--with-pcre在Nginx编译需要 PCRE(Perl Compatible Regular Expression),因为Nginx 的Rewrite模块和HTTP 核⼼模块会使⽤到PCRE正则表达式语法;
4、修改PATH
echo "PATH=/apps/nginx/sbin:${PATH}" > /etc/profile.d/nginx.sh
5、Nginx启动文件
[root@centos7 ~]# vim /lib/systemd/system/nginx.service
[Unit]
Description=The nginx HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/apps/nginx/logs/nginx.pid
ExecStartPre=/bin/rm -f /apps/nginx/logs/nginx.pid
ExecStartPre=/apps/nginx/sbin/nginx -t
ExecStart=/apps/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true
[Install]
WantedBy=multi-user.target
6、启动服务
systemctl daemon-reload #加载Nginx启动文件
systemctl enable --now nginx #开启服务器 或者 执行nginx
[root@centos7 ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:80 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 128 [::]:22 [::]:*
LISTEN 0 100 [::1]:25 [::]:*
二、Nginx四个主要目录
[root@centos7 ~]# tree /apps/nginx/
/apps/nginx/

conf:该⽬录中保存了nginx所有的配置⽂件,其中nginx.conf是nginx服务器的最核⼼最主要的配置⽂件,其他的.conf则是⽤来配置nginx相关的功能的,例如fastcgi功能使⽤的是fastcgi.conf和fastcgi_params两个⽂件,配置⽂件⼀般都有个样板配置⽂件,是⽂件名.default结尾,使⽤的使⽤将其复制为并将default去掉即可。
html:该⽬录中保存了nginx服务器的web⽂件,但是可以更改为其他⽬录保存web⽂件,另外还有⼀个50x的web⽂件是默认的错误⻚⾯提示⻚⾯。
logs:该⽬录⽤来保存nginx服务器的访问⽇志、错误⽇志等⽇志,logs⽬录可以放在其他路径,⽐如/var/logs/nginx⾥⾯。
sbin:该⽬录⽤来保存nginx⼆进制启动脚本,可以接受不同的参数以实现不同的功能。
