CentOS7 编译安装 Nginx (实测 笔记 Centos 7.0 + nginx 1.6.2) 环境： 系统硬件：vmware vsphere (CPU：2*4核，内存2G，双网卡) 系统版本：CentOS-7.0-1406-x86_64-DVD.iso
1.准备
1.1 显示系统版本
1.2 安装基本软件包 [root@centos ~]# yum install vim wget lsof gcc gcc-c++ bzip2 -y [root@centos ~]# yum install net-tools bind-utils -y
[root@centos ~]# ifconfig|grep inet inet 192.168.1.10 netmask 255.255.255.0 broadcast 192.168.1.255
2.1 下载包 [root@centos ~]# wget http://nginx.org/download/nginx-1.6.2.tar.gz [root@centos ~]# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz [root@centos ~]# wget http://zlib.net/zlib-1.2.8.tar.gz [root@centos ~]# wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz [root@centos ~]# wget http://www.canonware.com/download/jemalloc/jemalloc-3.6.0.tar.bz2
2.3 关闭selinux (不关有时会添加不了用户，或者重启后没法开机) 屏蔽以下两行 #SELINUX=enforcing #SELINUXTYPE=targeted 添加以下一行 SELINUXTYPE=disabled 保存，退出
重启后，查询是否关闭（显示Disabled则表示关闭） [root@centos ~]# shutdown -r now [root@centos ~]# getenforce Disabled
2.4 安装Pcre [root@centos ~]# cd /usr/local/src/ [root@centos ~]# tar zvxf pcre-8.36.tar.gz [root@centos ~]# cd pcre-8.36 [root@centos ~]# ./configure [root@centos ~]# make && make install
2.5 安装openssl [root@centos ~]# cd /usr/local/src/ [root@centos ~]# tar zvxf openssl-1.0.1j.tar.gz [root@centos ~]# cd openssl-1.0.1j [root@centos ~]# ./config [root@centos ~]# make && make install
2.6 安装zlib [root@centos ~]# cd /usr/local/src/ [root@centos ~]# tar zvxf zlib-1.2.8.tar.gz [root@centos ~]# cd zlib-1.2.8 [root@centos ~]# ./configure [root@centos ~]# make && make install
2.7 安装jemalloc [root@centos ~]# cd /usr/local/src/ [root@centos ~]# tar xjf jemalloc-3.6.0.tar.bz2 [root@centos ~]# cd jemalloc-3.6.0 [root@centos ~]# ./configure [root@centos ~]# make && make install [root@centos ~]# echo '/usr/local/lib' > /etc/ld.so.conf.d/local.conf [root@centos ~]# ldconfig
2.3 创建www用户和组，创建www虚拟主机使用的目录，以及Nginx使用的日志目录，并且赋予他们适当的权限 [root@centos ~]# groupadd www [root@centos ~]# useradd -g www www -s /sbin/nologin [root@centos ~]# mkdir -p /data/www [root@centos ~]# chmod +w /data/www [root@centos ~]# chown -R www:www /data/www ***如果没法创建用户，需要检查SELinux状态是否关闭
2.8 安装nginx [root@centos ~]# cd /usr/local/src/ [root@centos ~]# tar zvxf nginx-1.6.2.tar.gz [root@centos ~]# cd nginx-1.6.2 [root@centos ~]# ./configure --prefix=/opt/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/usr/local/src/openssl-1.0.1j --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.36 --with-ld-opt="-ljemalloc" [root@centos ~]# make && make install 2.9 修改 nginx.conf [root@centos ~]# vim /opt/nginx/conf/nginx.conf 修改前面几行为： user www www; worker_processes auto;
error_log logs/error.log crit;
events{
[root@centos ~]# vim /data/www/index.html
<html>
[root@centos ~]# cd /opt/nginx [root@centos ~]# ldconfig [root@centos ~]# ./sbin/nginx -c /opt/nginx/conf/nginx.conf -t 如果显示下面信息，即表示配置没问题
nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
[root@centos ~]# ./sbin/nginx -c /opt/nginx/conf/nginx.conf [root@centos ~]# lsof -n | grep jemalloc
ginx 2346 root mem REG 253,1 1824470 51571788 /usr/local/lib/libjemalloc.so.1
[root@centos ~]# iptables -L|grep ACCEPT [root@centos ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent [root@centos ~]# firewall-cmd --reload [root@centos ~]# iptables -L|grep ACCEPT
2.13 浏览器打开 http://192.168.1.10 显示出欢迎内容，则表示成功
[root@centos ~]# vim /usr/lib/systemd/system/nginx.service 增加以下内容
[Unit]
[Service]
[Install] :wq 保存退出
[root@centos ~]# systemctl enable nginx.service [root@centos ~]# systemctl list-unit-files|grep enabled|grep nginx
[root@centos ~]# ./sbin/nginx -s stop [root@centos ~]# systemctl daemon-reload [root@centos ~]# systemctl start nginx.service [root@centos ~]# systemctl status nginx.service -l [root@centos ~]# ps -ef|grep nginx
[root@centos ~]# lsof -n | grep jemalloc |
