centos7 搭建postfix

https://www.cnblogs.com/flytor/p/11461227.html#!comments

由于CentOS7默认安装的是MariaDB，所以要添加MySQL的yum源，有些编译需要的devel包只有epel扩展源有，所以我们需要把epel源也一并添加。因为是通过wget命令从下载地址中下载，但是最小化安装的CentOS7不自带wget命令，还需要先安装这个命令：

yum install -y wget
wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm

https://blog.csdn.net/qq_31708763/article/details/86498571

解决方式一：

innodb_buffer_pool_size = 8M （安装MySQL5.6到小于1G内存服务器上，启动MySQL会失败，报内存分配失败的错误，此时，需要修改my.cnf的内存大小从标准128M设置到8M或者64M）

解决方式二：

增加swap缓存，查看free -m或者free -h

##创建大小为1024M的文件
dd if=/dev/zero of=/swapfile bs=1M count=1024
##将该文件变为swap
mkswap /swapfile
##启用swap文件
swapon /swapfile

1、首先需要安装编译环境及其他所需要的包，免得一会编译过程中老报缺少包的错误，因为需要安装的包有点多，所以这个过程有点慢

yum install nginx vim gcc gcc-c++ openssl openssl-devel db4-devel ntpdate mysql mysql-devel mysql-server bzip2 php-mysql cyrus-sasl-md5 perl-GD perl-DBD-MySQL perl-GD perl-CPAN perl-CGI perl-CGI-Session cyrus-sasl-lib cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel libtool-ltdl-devel telnet mail libicu-devel -y

2.首先卸载系统自带的postfix，并删除postfix用户，重新指定uid、gid创建新用户postfix，postdrop，嫌一条条命令去执行有点麻烦就写成脚本文件去执行：

yum remove postfix -y
userdel postfix
groupdel postdrop
groupadd -g 2525 postfix
useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
groupadd -g 2526 postdrop
useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

3、在make install环节的时候会有个交互式的界面，可以自定义一些目录，我这里只更改了第二项临时文件目录，其他的都选择了默认目录：

wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.0.11.tar.gz
tar -zxvf postfix-3.0.11.tar.gz
cd postfix-3.0.11
make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lrt -lm -L/usr/lib64/sasl2 -lsasl2 -lssl -lcrypto'
make && make install
echo $?

4、更改目录的属主和属组：

chown -R postfix:postdrop /var/spool/postfix
chown -R postfix:postdrop /var/lib/postfix/
chown root /var/spool/postfix
chown -R root /var/spool/postfix/pid

5.修改postfix的配置文件：

# vim /etc/postfix/main.cf

myhostname = mail.xiongyang.top
# //设置主机名
　　mydomain = xiongyang.top

　　myhostname = mail.everyoo.com //设置主机名

inet_interfaces = //all指定postfix系统监听的网络接口
mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain //指定postfix接收邮件时收件人的域名 [使用虚拟域需要禁用]
mynetworks_style = host //指定信任网段类型
mynetworks = 192.168.77.1/24, 127.0.0.0/8 //指定信任的客户端
relay_domains = $mydestination //指定允许中转邮件的域名
alias_maps = hash:/etc/aliases //设置邮件的别名

6.然后需要在/etc/init.d/目录下提供一个脚本来管理postfix的启动与停止：

[root@localhost /var/www/extsuite/extman]# vim /etc/init.d/postfix

#!/bin/bash
#
# postfix Postfix Mail Transfer Agent
#
# chkconfig: 2345 80 30
# description: Postfix is a Mail Transport Agent, which is the program \
# that moves mail from one machine to another.

# Source function library.

# Source networking configuration.

# Check that networking is up.
[ $NETWORKING = "no" ] && exit 3
 
[ -x /usr/sbin/postfix ] || exit 4
[ -d /etc/postfix ] || exit 5
[ -d /var/spool/postfix ] || exit 6
 
RETVAL=0
prog="postfix"
 
start() {
# Start daemons.
echo -n $"Starting postfix: "
/usr/bin/newaliases >/dev/null 2>&1
/usr/sbin/postfix start 2>/dev/null 1>&2 && success || failure $"$prog start"
RETVAL=$?
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/postfix
echo
return $RETVAL
}
 
stop() {
# Stop daemons.
echo -n $"Shutting down postfix: "
/usr/sbin/postfix stop 2>/dev/null 1>&2 && success || failure $"$prog stop"
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/postfix
echo
return $RETVAL
}
 
reload() {
echo -n $"Reloading postfix: "
/usr/sbin/postfix reload 2>/dev/null 1>&2 && success || failure $"$prog reload"
RETVAL=$?
echo
return $RETVAL
}
 
abort() {
/usr/sbin/postfix abort 2>/dev/null 1>&2 && success || failure $"$prog abort"
return $?
}
 
flush() {
/usr/sbin/postfix flush 2>/dev/null 1>&2 && success || failure $"$prog flush"
return $?
}
 
check() {
/usr/sbin/postfix check 2>/dev/null 1>&2 && success || failure $"$prog check"
return $?
}
 
restart() {
stop
start
}
 
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
reload)
reload
;;

abort
;;
flush)

[ -f /var/lock/subsys/postfix ] && restart || :
;;
*)
echo $"Usage: $0 {start|stop|restart|reload|abort|flush|check|status|condrestart}"
exit 1
esac
 
exit $?

为脚本添加执行权限，并将服务添加到开机启动项中：

chmod +x /etc/init.d/postfix
chkconfig --add postfix
chkconfig postfix on
chown postfix.postfix -R /var/lib/postfix/
chown postfix.postfix /var/spool/  -R

3. 安装dovecot

yum安装：

[root@localhost ~]# yum install -y dovecot dovecot-mysql

配置dovecot：

[root@localhost ~]# cd /etc/dovecot/
[root@localhost dovecot]# vim dovecot.conf //直接在配置文件最后添加即可
protocols = imap pop3
!include conf.d/*.conf
listen = *
base_dir = /var/run/dovecot/

[root@localhost dovecot]# cd conf.d/
[root@localhost conf.d]# vim 10-auth.conf
disable_plaintext_auth = no

[root@localhost conf.d]# vim 10-mail.conf
mail_location = maildir:~/Maildir
mail_location = maildir:/var/mailbox/%d/%n/Maildir
mail_privileged_group = mail

[root@localhost conf.d]# vim 10-ssl.conf
ssl = no

[root@localhost conf.d]# vim 10-logging.conf
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot.info
log_timestamp = "%Y-%m-%d %H:%M:%S "

[root@localhost conf.d]# cp auth-sql.conf.ext auth-sql.conf
[root@localhost conf.d]# vim auth-sql.conf
passdb {
driver = sql
 
# Path for SQL configuration file, see example-config/dovecot-sql.conf.ext
args = /etc/dovecot/dovecot-sql.conf.ext
}
 
userdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf.ext
}

编辑dovecot通过mysql认证的配置文件：

[root@localhost conf.d]# vim /etc/dovecot-mysql.conf
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'
user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'

安装courier-authlib

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# wget https://sourceforge.net/projects/courier/files/authlib/0.66.2/courier-authlib-0.66.2.tar.bz2
[root@localhost /usr/local/src]# tar -jxvf courier-authlib-0.66.2.tar.bz2
[root@localhost /usr/local/src]# cd courier-authlib-0.66.2
[root@localhost /usr/local/src/courier-authlib-0.66.2]# ./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --without-authpam --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/lib64/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-mailuser=postfix
[root@localhost /usr/local/src/courier-authlib-0.66.2]# make && makeinstall

编译过程中发生了一个错误：

configure: error: The Courier Unicode Library 1.2 appears not to be installed. You may need to install a separate development subpackage, in addition to the main package

这是因为Courier Unicode Library没有安装，我们下载courier-unicode-1.2并编译安装：

[root@localhost ~]# wget https://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2
[root@localhost ~]# tar jxvf courier-unicode-1.2.tar.bz2
[root@localhost ~]# cd courier-unicode-1.2
[root@localhost courier-unicode-1.2]# ./configure
[root@localhost courier-unicode-1.2]# make && make install

完成Courier Unicode Library的安装后，倒回去再次编译courier-authlib就没问题了

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# cd courier-authlib-0.66.2
[root@localhost /usr/local/src/courier-authlib-0.66.2]# ./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --without-authpam --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/lib64/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-mailuser=postfix
[root@localhost /usr/local/src/courier-authlib-0.66.2]# make && make install

配置courier-authlib：

[root@localhost courier-authlib-0.66.2]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon
[root@localhost courier-authlib-0.66.2]# cp /etc/authdaemonrc.dist /etc/authdaemonrc
[root@localhost courier-authlib-0.66.2]# cp /etc/authmysqlrc.dist /etc/authmysqlrc
[root@localhost courier-authlib-0.66.2]# vim /etc/authdaemonrc //配置文件里的验证方法比较多，我们这里只使用authmysql
authmodulelist="authmysql"
authmodulelistorig="authmysql"
#yang
authmodulelist="authuserdb authpwd authmysql authcustom authpipe"
authmodulelistorig="authuserdb authpwd authmysql authcustom authpipe"
#endyang

[root@localhost courier-authlib-0.66.2]# vim /etc/authmysqlrc //直接添加到配置文件尾部，然后去上面将响应系统默认的注视掉，或者删除即可
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_PORT 3306
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
DEFAULT_DOMAIN test.com
MYSQL_UID_FIELD '2525'
MYSQL_GID_FIELD '2525'
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/var/mailbox/',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)

courier-authlib添加服务启动脚本及其他：

[root@localhost courier-authlib-0.66.2]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
[root@localhost courier-authlib-0.66.2]# chmod +x /etc/init.d/courier-authlib
[root@localhost courier-authlib-0.66.2]# chkconfig --add courier-authlib
[root@localhost courier-authlib-0.66.2]# chkconfig courier-authlib on
[root@localhost courier-authlib-0.66.2]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf
[root@localhost courier-authlib-0.66.1]# ldconfig
[root@localhost courier-authlib-0.66.1]# service courier-authlib start
Starting Courier authentication services: authdaemond

smtp以及虚拟用户相关的设置：

[root@localhost ~]# vim /usr/lib64/sasl2/smtpd.conf //文件不存在，要自己创建
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
[root@localhost ~]# vim /etc/postfix/main.cf
##postfix支持SMTP##
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = ''
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
broken_sasl_auth_clients=yes
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sasl_security_options = noanonymous
##postfix支持虚拟用户##
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf //这里的配置文件需在后面extman里复制过来
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_uid_maps = static:2525
virtual_gid_maps = static:2525
virtual_transport = virtual

安装extmail

下载extmail和extman：（可以从GitHub 下载）

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz （失效 https://github.com/xyoun/extmail/blob/master/extmail-1.2.tar.gz）
[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz （失效 https://github.com/xyoun/extmail/blob/master/extman-1.1.tar.gz）

创建站点目录并解压、重命名extmail包：

[root@localhost /usr/local/src]# mkdir -p /var/www/extsuite
[root@localhost /usr/local/src]# tar -zxvf extmail-1.2.tar.gz -C /var/www/extsuite/
[root@localhost /usr/local/src]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail

更改extmail的配置文件：

[root@localhost ~]# cd /var/www/extsuite/extmail
[root@localhost extmail]# cp webmail.cf.default webmail.cf
[root@localhost extmail]# vim webmail.cf
SYS_SESS_DIR = /tmp/extmail
SYS_UPLOAD_TMPDIR = /tmp/extmail/upload
SYS_USER_LANG = zh_CN
SYS_MIN_PASS_LEN = 8
SYS_MAILDIR_BASE = /var/mailbox
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock
SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password
SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

建立临时文件目录与session目录，并更改权限：

[root@localhost extmail]# mkdir -p /tmp/extmail/upload
[root@localhost extmail]# chown -R postfix.postfix /tmp/extmail/

安装extman

回到extman的下载目录下，解压extman包：

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# tar -zxvf extman-1.1.tar.gz -C /var/www/extsuite/
[root@localhost /usr/local/src]# cd /var/www/extsuite/
[root@localhost /var/www/extsuite]# mv extman-1.1/ extman

拷贝extman的配置文件：

[root@localhost /var/www/extsuite]# cd extman/
[root@localhost /var/www/extsuite/extman]# cp webman.cf.default webman.cf

更改cgi目录的属主属组：

[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

导入数据库：
由于数据库不能识别TYPE=MyISAM，所以这里直接导入会出错，需要先编辑extmail.sql数据库文件，将文件中的TYPE=MyISAM更改为ENGINE=MyISAM，共有五处修改：

[root@localhost /var/www/extsuite/extman]# vim docs/extmail.sql
:% s/TYPE/ENGINE/g      （vim 语法）

我这里导入数据的时候发生了一个错误，提示找不到mysql.sock文件：

[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@localhost /var/www/extsuite/extman]# ls /var/lib/mysql/mysql.sock
ls: 无法访问/var/lib/mysql/mysql.sock: 没有那个文件或目录

解决：然后我去查看了一下/etc/my.cnf文件，发现没问题，socket参数指向的也是 /var/lib/mysql/mysql.sock 这个路径，于是我就重启了mysql服务(systemctl restart mysqld.service)，然后再尝试就没有报找不到mysql.sock文件的错误了，但是报了另一个错误：

[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql
ERROR 1364 (HY000) at line 31: Field 'ssl_cipher' doesn't have a default value
[root@localhost /var/www/extsuite/extman]#

这错误的意思是：字段 'ssl密码' 没有默认值

于是又得去查看一下/etc/my.cnf文件，然后把sql_mode参数给注释掉

# Recommended in standard MySQL setup
# sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

接着重启mysql服务后，继续导入数据，这次就没问题了：

[root@vultr extman]# systemctl restart mysqld.service
[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql
[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/init.sql

导入数据成功后再次修改/etc/my.cnf文件，把刚刚注释的那行给去掉注释，不去掉的话，mysql服务可能会出现不能启动的问题：

# Recommended in standard MySQL setup
  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

数据导入成功后，登录mysql，创建一个mysql数据库用户extmail并授予权限

[root@vultr extman]# mysql -uroot
mysql>  GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail';  //我这里是直接授予全部权限在任意的IP地址上了，实际情况根据需求而定

Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye

复制之前提到的配置文件：

[root@localhost ~]# cd /var/www/extsuite/extman/docs/
[root@localhost /var/www/extsuite/extman/docs]# cp mysql_virtual_* /etc/postfix/

为extman创建临时目录：

[root@localhost /var/www/extsuite/extman/docs]# mkdir /tmp/extman
[root@localhost /var/www/extsuite/extman/docs]# chown -R postfix.postfix /tmp/extman/

启动postfix、dovecot、saslauthd服务，并查看进程是否正常:

7. 测试

测试虚拟用户：

[root@vultr docs]#  /usr/local/courier-authlib/sbin/authtest -s login postmaster@extmail.org extmail
Authentication succeeded. //显示这个表示成功，测试时使用的是postmaster@extmail.org，因为我们导入的数据库init.sql里面自带了这个

     Authenticated: postmaster@extmail.org  (uid 2525, gid 2525)
    Home Directory: /var/mailbox/extmail.org/postmaster     //这里需要注意/var/mailbox这个目录现在我们还没有创建，后面web访问的时候如果没有会报错,所以提前创建。
           Maildir: /var/mailbox/extmail.org/postmaster/Maildir/
             Quota: (none)
Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0
Cleartext Password: extmail
           Options: (none)

[root@vultr docs]# mkdir /var/mailbox
[root@vultr docs]# chown -R postfix.postfix /var/mailbox/

测试smtp发信：

[root@vultr docs]# printf "postmaster@extmail.org" | openssl base64

8. 启动nginx实现web访问

nginx本身并不能解析cgi，extmail自带了解析cgi的程序，但是有些地方需要修改

[root@localhost ~]# vim /var/www/extsuite/extmail/dispatch-init
SU_UID=postfix
SU_GID=postfix

启动dispatch-init：

[root@vultr down]# /var/www/extsuite/extmail/dispatch-init start
Starting extmail FCGI server...
[root@vultr down]# /var/www/extsuite/extman/daemon/cmdserver -v -d
loaded ok

添加nginx虚拟主机

vim /etc/nginx/conf.d/extmail.conf

文件内容如下：

server {
listen 8080;
server_name mail.xiongyang.top;
index index.html index.htm index.php index.cgi;
root /var/www/extsuite/extmail/html/;
location /extmail/cgi/ {
fastcgi_pass 127.0.0.1:8888;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME /var/www/extsuite/extmail/cgi/$fastcgi_script_name;
include fcgi.conf;
}
location /extmail/ {
alias /var/www/extsuite/extmail/html/;
}
location /extman/cgi/ {
fastcgi_pass 127.0.0.1:8888;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME /var/www/extsuite/extman/cgi/$fastcgi_script_name;
include fcgi.conf;
}
location /extman/ {
alias /var/www/extsuite/extman/html/;
}
access_log /var/log/extmail_access.log;
}

创建fcgi.conf文件：

vim /etc/nginx/fcgi.conf

文件内容如下：

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;

安装Unix::Syslog：

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz
[root@localhost /usr/local/src]# tar zxvf Unix-Syslog-1.1.tar.gz
[root@localhost /usr/local/src]# cd Unix-Syslog-1.1
[root@localhost /usr/local/src/Unix-Syslog-1.1]# perl Makefile.PL
[root@localhost /usr/local/src/Unix-Syslog-1.1]# make && make inst

启动nginx，并检查进程和监听端口是否正常：

[root@vultr Unix-Syslog-1.1]# service nginx start
Redirecting to /bin/systemctl start nginx.service
[root@vultr Unix-Syslog-1.1]# ps aux |grep nginx
root     10830  0.0  0.4 105476  2032 ?        Ss   19:47   0:00 nginx: master process /usr/sbin/nginx
