[root@localhost ~]# systemctl status httpd

1.rpm包方式

（1）下载扩展源

（2）安装 扩展rpm包，nginx -V查看 配置参数，后面源码 安装 时要 用到

[root@localhost ~]# yum install https://nginx.org/packages/centos/7Server/x86_64/RPMS/nginx-debuginfo-1.22.0-1.el7.ngx.x86_64.rpm
[root@localhost ~]# yum install nginx-1.22.0-1.el7.ngx.x86_64.rpm -y
[root@localhost ~]# systemctl start nginx
[root@localhost ~]# curl localhost
hello
[root@localhost ~]# nginx -v
nginx version: nginx/1.22.0
[root@localhost ~]# nginx -V
nginx version: nginx/1.22.0
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

（3）默认的配置文件 位置和html 存放 位置

默认nginx.conf位置”/etc/nginx/nginx.conf“

默认采用引用“/etc/nginx/conf.d”下的default.conf文件这种方式

默认的html文件存放位置”/usr/share/nginx/html“

[root@localhost ~]# rpm -ql nginx
/etc/logrotate.d/nginx
/etc/nginx
/etc/nginx/conf.d
/etc/nginx/conf.d/default.conf
/etc/nginx/fastcgi_params
/etc/nginx/mime.types
/etc/nginx/modules
/etc/nginx/nginx.conf
/etc/nginx/scgi_params
/etc/nginx/uwsgi_params
/usr/lib/systemd/system/nginx-debug.service
/usr/lib/systemd/system/nginx.service
/usr/lib64/nginx
/usr/lib64/nginx/modules
/usr/libexec/initscripts/legacy-actions/nginx
/usr/libexec/initscripts/legacy-actions/nginx/check-reload
/usr/libexec/initscripts/legacy-actions/nginx/upgrade
/usr/sbin/nginx
/usr/sbin/nginx-debug
/usr/share/doc/nginx-1.22.0
/usr/share/doc/nginx-1.22.0/COPYRIGHT
/usr/share/man/man8/nginx.8.gz
/usr/share/nginx
/usr/share/nginx/html
/usr/share/nginx/html/50x.html
/usr/share/nginx/html/index.html
/var/cache/nginx
/var/log/nginx

2.源码方式

（1）建议提前下好所需要的部分包

[root@localhost nginx-1.22.0]# yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

（2）下载tar.gz包

（3）建议将包解压到/usr/local/src下，执行 configure文件

[root@localhost nginx-1.22.0]# pwd
/usr/local/src/nginx-1.22.0

[root@localhost nginx-1.22.0]# ./configure 
--prefix=/etc/nginx

--with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

[root@localhost nginx-1.22.0]# yum install -y openssl-devel

--with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

（5）一直到这步，configure文件就执行好了

（6）make，make install 编译安装

[root@localhost nginx-1.22.0]# make 
[root@localhost nginx-1.22.0]# make install
[root@localhost nginx-1.22.0]# nginx -V

安装完成

三.nginx部分 目录 结构

1.conf目录

2.html 目录

[root@localhost nginx-1.22.0]# tree html
html
├── 50x.html   # 错误页面替代显示文件，出现错误时调用这个页面
└── index.html   # 默认的首页文件， 在实际环境中，一般用index.html、 index.php或index.jsp来做

四.nginx配置文件 说明

[root@localhost ~]# vim /etc/nginx/nginx.conf #rpm包在这个文件，源码安装的配置文件是/usr/local/src/nginx-1.22.0/conf/nginx.conf 
user  nginx;     #用户
worker_processes  auto;    #主模块命令，指定bnginx要开启的进程数，一般指定一个，如果cpu多多和，则和cpu数量一致即可

error_log  /var/log/nginx/error.log notice;   #主模块命令，全局错误日志，debug（最详细），info，notice，warn，error，crit（最简略）
pid        /var/run/nginx.pid;  #主模块命令，指定进程id的存储文件位置

#events指定设定nginx的工作模式和连接上限
events { 
    #use 模式      （事件模块指令，放在events中指定nginx的工作模式，select-标准工作模式，poll-标准工作模式，kqueue-BDS系统高效工作模式，epoll-Linux平台首选高效工作模式，rtsig，/dev/poll）
    worker_connections  1024;   #事件模块指令，定义每个进程的最大连接数，默认1024，max_client客户端连接数=worker_processes*worker_connections，max_clients=worker_processes*worker_connections/4，当然这些设置也受文件系统打开数量限制，执行名“ulimit -n 65535”后生效
}

#http服务配置
http {
    include       /etc/nginx/mime.types;    #include主模块命令，include配置文件
    default_type  application/octet-stream;  #http核心模块指令，octet-stream默认二进制流

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;   #高效传输模式
    #tcp_nopush     on;

    keepalive_timeout  65;   #超时时间
	server {                    #server 区块
		listen 80;          #端口
	server_name localhost;      #域名
	location / {               #location区块，可以写多个
		root html;           #站点目录，路径不定，按我的源码安装方式那就在/usr/local/src/nginx-1.22.0/html
		index index.html index.htm;     #首页文件
		} 
	error_page 500 502 503 504 /50x.html;        #错误信息配置
	location = /50x.html {         #html文件位置
		root html;          #路径
		}
	}
    #gzip  on;  #是否开启压缩
include /etc/nginx/conf.d/*.conf;
}

五.配置nginx的service 管理

1.切换到service 配置目录

[root@localhost ~]# cd /usr/lib/systemd/system/
[root@localhost system]# whereis nginx
nginx: /usr/sbin/nginx /etc/nginx                #查找出来的路径稍后会用到

2.编辑nginx.serv ice文件

[root@localhost system]# vim nginx.service 
[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t -c /usr/local/src/nginx-1.22.0/conf/nginx.conf
#指定你刚才查到的目录和你的nginx配置文件
ExecStart=/usr/sbin/nginx -c /usr/local/src/nginx-1.22.0/conf/nginx.conf
#同上
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

[root@localhost ~]# systemctl daemon-reload   #重载配置

3.创建nginx用户

[root@localhost nginx-1.22.0]# useradd -M -s /sbin/nologin nginx

4.启动 测试

（1）我的开始报了这两个 问题

nginx: [emerg] getpwnam(“nginx”) failed（第三步没做或没成功就会报没有nginx，重新执行即可）

解决：

[root@localhost conf]# useradd -M -s /sbin/nologin nginx

nginx: [emerg] mk dir() “/var/cache/nginx/client_temp” failed (2: No such file or directory)（没有这个目录）

解决：

[root@localhost nginx-1.22.0]# mkdir /var/cache/nginx/client_temp -pv
mkdir: created directory ‘/var/cache/nginx’
mkdir: created directory ‘/var/cache/nginx/client_temp’

（2）开启/关闭

[root@localhost ~]# systemctl start nginx
[root@localhost ~]# systemctl status nginx

（3）测试 页面

将nginx.conf此处改为绝对路径

[root@localhost nginx-1.22.0]# echo nihao > html/index.html
[root@localhost nginx-1.22.0]# curl localhost
