CentOS7 编译安装 Nginx (实测 笔记 Centos 7.0 + nginx 1.6.2)

时间:2016-04-10 00:26  来源:linux.it.net.cn   作者:IT

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


安装步骤：

1.准备

1.1 显示系统版本
[root@centos ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)


[root@centos ~]# uname -a
Linux tCentos7 3.10.0-123.13.1.el7.x86_64 #1 SMP Tue Dec 9 23:06:09 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

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


1.3 显示IP地址 (centos7需要先安装 net-tools bind-utils包)

[root@centos ~]# ifconfig|grep inet

inet 192.168.1.10 netmask 255.255.255.0 broadcast 192.168.1.255


2.编译安装nginx

2.1 下载包
[root@centos ~]# cd /usr/local/src/

[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


2.2 安装依赖
[root@centos ~]# yum install zlib-devel openssl-devel -y

 

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)
[root@centos ~]#  vim /etc/selinux/config

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;

pid logs/nginx.pid;

events{
　　use epoll;
　　worker_connections 65535;
}


找到，并修改 root 行的内容
location / {
root /data/www;
index index.html index.htm;
}


保存，退出


2.10 建立测试首页

[root@centos ~]# vim /data/www/index.html

<html>
<head><title>nginx index.html</title></head>
<body>
<h1>index.html</h1>
</body>
</html>

保存，退出


2.11 测试和运行

[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
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful


查看jemalloc是否生效，需要先启动nginx

[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
nginx 2347 www mem REG 253,1 1824470 51571788 /usr/local/lib/libjemalloc.so.1
nginx 2348 www mem REG 253,1 1824470 51571788 /usr/local/lib/libjemalloc.so.1
nginx 2349 www mem REG 253,1 1824470 51571788 /usr/local/lib/libjemalloc.so.1
nginx 2350 www mem REG 253,1 1824470 51571788 /usr/local/lib/libjemalloc.so.1


2.12 防火墙添加80端口

[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

 


2.14 作为服务，开机后启动

[root@centos ~]# vim /usr/lib/systemd/system/nginx.service

增加以下内容

[Unit]
Description=The nginx HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/opt/nginx/logs/nginx.pid
ExecStartPre=/opt/nginx/sbin/nginx -c /opt/nginx/conf/nginx.conf -t 
ExecStart=/opt/nginx/sbin/nginx -c /opt/nginx/conf/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

:wq 保存退出

 

[root@centos ~]# systemctl enable nginx.service

[root@centos ~]# systemctl list-unit-files|grep enabled|grep nginx


2.15 启动服务

[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
