linux下安装nginx

1、添加nginx服务进程用户

# groupadd -r nginx
# useradd -r -g nginx nginx

2、下载

记得挑选自己喜欢的版本
http://nginx.org/download
可以在远程主机直接下载

# wget  http://nginx.org/download/nginx-1.9.9.tar.gz

也可以用该地址下载之后自己上传到远程主机

3、解压

# tar -zxvf nginx-1.9.9.tar.gz

4、部署

先进入到解压完成的nginx目录下

# cd nginx-1.9.9/

然后安装，最简单的安装是这样，没有添加第三方模块，不过一般都不够用
/usr/local/nginx是安装路径，可以根据需要自己修改

./configure --prefix=/usr/local/nginx

后面配置的时候会发现需要的好多模块都没有。
索性就把所有模块都安装了吧

# ./configure  --prefix=/usr/local/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=/var/run/nginx.pid  --lock-path=/var/run/nginx.lock  --http-client-body-temp-path=/var/tmp/nginx/client  --http-proxy-temp-path=/var/tmp/nginx/proxy  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi  --http-scgi-temp-path=/var/tmp/nginx/scgi  --user=nginx  --group=nginx  --with-pcre  --with-http_v2_module  --with-http_ssl_module  --with-http_realip_module  --with-http_addition_module  --with-http_sub_module  --with-http_dav_module  --with-http_flv_module  --with-http_mp4_module  --with-http_gunzip_module  --with-http_gzip_static_module  --with-http_random_index_module  --with-http_secure_link_module  --with-http_stub_status_module  --with-http_auth_request_module  --with-mail  --with-mail_ssl_module  --with-file-aio  --with-ipv6  --with-http_v2_module  --with-threads  --with-stream  --with-stream_ssl_module 

如果出现如下错误

checking for C compiler ... not found

需要执行

# yum -y install gcc gcc-c++ autoconf automake make

再次安装
可能会出现下一个错误

./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.

如果出现了，就执行这个

# yum -y install openssl openssl-devel

后面如果是这样就是执行成功了

creating objs/Makefile

  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx modules path: "/usr/local/nginx/modules"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

5、编译

# make

结尾如下

objs/ngx_modules.o \
-ldl -lpthread -lcrypt -lpcre -lz \
-Wl,-E
sed -e "s|%%PREFIX%%|/usr/local/nginx|" \
        -e "s|%%PID_PATH%%|/usr/local/nginx/logs/nginx.pid|" \
        -e "s|%%CONF_PATH%%|/usr/local/nginx/conf/nginx.conf|" \
        -e "s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|" \
        < man/nginx.8 > objs/nginx.8
make[1]: Leaving directory `/usr/local/nginx/nginx-1.9.9'

6、安装

# make install

结尾是这样的话应该就是完成了

test -d '/usr/local/nginx/logs' \
        || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/logs' \
        || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/html' \
        || cp -R html '/usr/local/nginx'
test -d '/usr/local/nginx/logs' \
        || mkdir -p '/usr/local/nginx/logs'
make[1]: Leaving directory `/usr/local/nginx/nginx-1.9.9'

7、启动

参数 -c 指定了配置文件的路径，如果不加的话就是使用默认的配置文件

# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

查看是否启动

# ps -ef | grep nginx

然后在浏览器输入IP 默认端口是80
看到这样的 就是成功了
