Linux系统下nginx的安装

• centos7
• nginx1.21.4

• id mynginx || useradd -s /sbin/nologin mynginx
  • 此用户用于启动nginx，若不存在此用户，将创建此用户，存在则不执行

• mkdir -p /nginx
  • 将下载的nginx安装包存放到此目录
• cd /nginx

• curl -O http://nginx.org/download/nginx-1.21.4.tar.gz

• tar xf nginx-1.21.4.tar.gz
• cd nginx-1.21.4

• yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gcc-c++ autoconf automake make

• ./configure --user=mynginx --group=mynginx --prefix=/usr/local/mynginx --with-threads --with-http_ssl_module --with-http_realip_module --with-file-aio --with-http_stub_status_module --with-stream

• make -j 2
• make install

• echo “PATH=$PATH:/usr/local/mynginx/sbin” >>/root/.bashrc
• source /root/.bashrc

• /usr/local/mynginx/sbin/nginx
  • 建议使用绝对路径

• service firewalld stop
• systemctl disable firewalld
• sed -i ‘/^SELINUX=/s/enforcing/disabled/’ /etc/sysconfig/selinux

cd nginx-1.21.4
#解决依赖关系
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gcc-c++ autoconf automake make
#生成编译前的配置工作，生成Makefile
./configure --user=mynginx --group=mynginx --prefix=/usr/local/mynginx --with-threads --with-http_ssl_module --with-http_realip_module --with-file-aio --with-http_stub_status_module --with-stream
#编译
make -j 2
#编译安装
make install 
#修改path变量
echo "PATH=$PATH:/usr/local/mynginx/sbin" >>/root/.bashrc
#执行修改了环境变量的脚本
source /root/.bashrc
#启动nginx
/usr/local/mynginx/sbin/nginx
#关闭防火墙
service firewalld stop
