centos7安装nginx的三种方式~yum源，源码，Docker

1.yum安装：Centos7源默认没有nginx

2.源码安装：

3.Docker安装：

1.yum安装：Centos7源默认没有nginx

配置yum源：

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

查看nginx源：
```
yum list | grep nginx
```
安装nginx：
```
yum install -y nginx
```
查看是否安装成功：
```
nginx -v
```
查看nginx的安装目录:
```
rpm -qc nginx
```

2.源码安装：

下载tengine包：

wget -c http://tengine.taobao.org/download/tengine-2.3.0.tar.gz      # -c支持断点续传

链接：https://pan.baidu.com/s/1Gko5dOpntrIwzio5i35K-g 
提取码：7bpf

http://tengine.taobao.org/download.html

解压：

tar -zxvf tengine-2.3.0.tar.gz -C /usr/local

修改目录名：
```
cd /usr/local;mv tengine-2.3.0 tengine
```
安装 Nginx 所需的 pcre 库（rewrite 规则）
```
yum install -y pcre-devel
```
安装 openssl 相关包：如果不安装 openssl 相关包，安装Nginx 的过程中会报错
```
yum install -y openssl-devel
```

安装编译环境：

yum install gcc gcc-c++ make -y     # 编译需要编译环境

安装nginx

./configure \
--prefix=/usr/share/nginx \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/run/nginx.pid \
--lock-path=/run/lock/subsys/nginx \
--user=nginx --group=nginx \
--with-debug --with-file-aio \
--with-http_addition_module \
--with-http_auth_request_module \
--with-http_dav_module \
--with-http_degradation_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-pcre --with-pcre-jit \
--with-threads

编译并安装
```
make
make install
```

创建用户：

useradd -r -c "Nginx web server" -d /var/lib/nginx -M -s /sbin/nologin nginx
# -r：建立系统账号
# -c：注释 
# -d：家目录
# -M：不要自动建立用户的登入目录
# -s：指定shell

编写nginx的服务脚本：

cat << eof > /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx - high performance web server
After=network.target remote-fs.target nss-lookup.target
Description=Nginx
Wants=network-online.target

[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/usr/bin/rm -f /run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
ExecStop=/usr/sbin/nginx -s stop
ExecReload=/usr/sbin/nginx -s reload
PrivateTmp=true

[Install]
WanteBy=multi-user.target
eof

重载systemctl：
```
systemctl daemon-reload
```
重启：
```
systemctl restart nginx
```

3.Docker安装：

创建目录：
```
mkdir ~/nginx;cd ~/nginx;mkdir conf
```

复制别的nginx.conf文件，或者在conf目录下创建如下的nginx.conf配置文件文件：

scp root@IP地址:/etc/nginx/nginx.conf ./conf/nginx.conf

cat << eof > conf/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {worker_connections 1024;
}

http {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;tcp_nopush          on;tcp_nodelay         on;keepalive_timeout   65;types_hash_max_size 2048;
include             /etc/nginx/mime.types;default_type        application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.# See http://nginx.org/en/docs/ngx_core_module.html#include# for more information.include /etc/nginx/conf.d/*.conf;
server {listen       80 default_server;listen       [::]:80 default_server;server_name  _;root         /usr/share/nginx/html;
# Load configuration files for the default server block.include /etc/nginx/default.d/*.conf;
location / {}
error_page 404 /404.html;location = /40x.html {}
error_page 500 502 503 504 /50x.html;location = /50x.html {}}

# Settings for a TLS enabled server.
#
#    server {
#        listen       443 ssl http2 default_server;
#        listen       [::]:443 ssl http2 default_server;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        ssl_certificate "/etc/pki/nginx/server.crt";
#        ssl_certificate_key "/etc/pki/nginx/private/server.key";
#        ssl_session_cache shared:SSL:1m;
#        ssl_session_timeout  10m;
#        ssl_ciphers PROFILE=SYSTEM;
#        ssl_prefer_server_ciphers on;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }
eof

创建容器：

docker run -id --name=c_nginx 
-p 80:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx
