centos7.6从零开始编译nginx+mysql+php（二） 安装Nginx

[root@localhost ~]# mkdir /software
[root@localhost ~]# cd /software/

# 如果运行报错：-bash: wget: 未找到命令
# 那么说明你还没有安装wget命令，需要运行yum install wget先安装这个命令
[root@localhost software]# wget http://nginx.org/download/nginx-1.14.2.tar.gz

# 关闭系统防火墙 此文章是内网测试所用所以直接关闭防火墙也无所谓。
# 外网环境或者正式环境请根据对应的需求开放指定端口
[root@localhost software]# systemctl stop firewalld.service 
[root@localhost software]# systemctl disable firewalld.service 

# 关闭SElinux
[root@localhost software]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[root@localhost software]# setenforce 0

# 创建www账户 用来启动nginx
[root@localhost software]# useradd www -s /sbin/nologin
# 安装运行Nginx所依赖的包
[root@localhost software]# yum -y install pcre pcre-devel zlib zlib-devel gcc-c++ gcc openssl*

# 解压Nginx源码包
[root@localhost software]# tar zxvf nginx-1.14.0.tar.gz

# 进入解压后的目录，对Nginx进行配置
[root@localhost software]# cd nginx-1.14.0/
[root@localhost nginx-1.14.0]# ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_realip_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module  --with-pcre

# 编译和安装
[root@localhost nginx-1.14.0]# make && make install

# 启动Nginx
[root@localhost nginx-1.14.0]# /usr/local/nginx/sbin/nginx

# 关闭Nginx进程
# 如果报错 -bash: killall: 未找到命令，请运行 yum install psmisc 安装kill、killall命令。
[root@localhost nginx-1.14.0]# killall nginx

# 把nginx命令作为软连接
[root@localhost nginx-1.14.0]# ln -s /usr/local/nginx/sbin/nginx /sbin/nginx

# 编写nginx启动脚本
[root@localhost nginx-1.14.0]# cat >> /usr/lib/systemd/system/nginx.service << EOF
