centos7中安装Nginx

1.安装依赖库

yum update -y
yum install -y gcc gcc-c++
yum install pcre
yum install pcre-devel
yum install zlib
yum install zlib-devel
yum install openssl
yum install openssl-devel
yum install gd gd-devel

2.安装nginx

# 下载nginx
cd /usr/local
wget http://nginx.org/download/nginx-1.9.15.tar.gz
# 解压缩
tar -zxvf nginx-1.9.15.tar.gz
cd nginx-1.9.15
# 创建一个nginx组和nginx的用户(如果不指定用户，则后面配置user和group的时候填nobody)
groupadd nginx
useradd nginx -g nginx -s /sbin/nologin -M
# 准备编译
./configure \
--prefix=/usr/local/nginx \
--pid-path=/usr/local/nginx/run \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--with-pcre \
--with-http_image_filter_module
# 编译与安装
make && make install
# 安装完成后默认的地址为/usr/local/nginx,所以删除不需要的
rm -rf nginx-1.9.15
rm -rf nginx-1.9.15.tar.gz
# 切换目录
cd /lib/systemd/system
# 创建nginx的系统服务目录
vim nginx.service
# 添加如下内容
[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx reload
ExecStop=/usr/local/nginx/sbin/nginx quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target
# 开启Nginx
systemctl start nginx
# 开机自启动
systemctl enable nginx

bug

1. ./configure: error: the HTTP image filter module requires the GD library. You can either do not enable the module or install the libraries.
   没有安装gd gd-devel
2. Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
   启动报错，使用systemctl status nginx查看的时候，显示Process: 24899 ExecStart=/usr/local/nginx/sbin/nginx (code=exited, status=1/FAILURE)
   查看端口
   netstat -aptn
   没有发现问题
   查看进程
   ps -ef |grep nginx
   发现nginx已经启动了
   root 24946 11815 0 15:41 pts/1 00:00:00 grep --color=auto nginx
   然后手动关闭
   kill -9 11815
   然而没有用,查看日志
   tail /var/log/messages
   显示错误
   nginx: nginx: [emerg] getpwnam("nginx") failed
   创建一个nginx的用户
   useradd nginx -s /sbin/nologin -M
